I have a working 3D-printed prototype for a compact cosmetics travel palette and I’m looking for a fresh, professional industrial design perspective. I don’t need a ground-up redesign. I’m looking for a concise, expert review that helps improve the product’s overall look, usability, ergonomics and perceived quality before I move into a small pilot batch. The product needs to remain suitable for desktop 3D printing and simple home assembly. Picture a traveller opening this case on a cramped hotel vanity or airplane tray: the design should feel intuitive, secure, compact and visually appealing without adding unnecessary manufacturing complexity. The selected designer will review the current CAD file, photos of the first print, and notes on the known issues. ...

...is not off-the-shelf catalog picking, but original furniture concepts that feel unified yet fit the specific size, function, and lighting of each space. You’ll receive floor plans, photos, and the measurements I’ve already taken. From there, I expect full-room concept boards, 3D renders, and build-ready drawings that specify materials, finishes, and hardware I can source locally. Attention to ergonomics and durability is important; sleek lines and unobtrusive storage solutions are a plus. When you respond, please include examples of past work that prove you’ve handled whole-home or multi-room projects in a modern style—the portfolio matters more to me than a long proposal. If you excel at visualisation tools such as SketchUp, 3ds Max, or similar, let me ...

QueryPilot AI – Multi-User RAG Chatbot QueryPilot AI is a production-style Retrieval-Augmented Generation (RAG) application that lets users chat with their uploaded documents through a modern React frontend and a FastAPI backend. It combines semantic retrieval, vector search, chat history, and LLM-powered answering to provide context-aware responses from document knowledge. Overview This project is built as a multi-user document Q&A system where users can upload files, manage documents, and ask questions in a chat interface. The backend handles retrieval, chat sessions, and response generation, while the frontend provides a clean React-based UI for chatting, uploading, listing, and deleting documents. Tech Stack Frontend: React, Vite Backend: FastAPI LLM Orchestra...

...podded devices ont he market, similar to autometer gauges in sizing. The build involves six separate modules: a Waveshare 4.3-inch LCD, a 2.8-inch Waveshare LCD, and three 1.75-inch Waveshare pods. Every board’s buttons and memory-card slots must remain reachable once the pieces are printed and installed. Device clocking is already fixed in the save file; you may reposition components for better ergonomics or cable routing, but do not alter their set orientation. Because the final parts will be 3D-printed, please design with FDM tolerances in mind—reasonable wall thickness, clearance for fasteners, and minimal unsupported overhangs. The current .FCStd file in the repo shows baseline placement, so you can build directly on that. Deliverables • Updated FreeCAD...

I need assistance optimizing my online store's user experience. The focus areas include navigation, the checkout process, and mobile responsiveness. Key elements for improvement are menu structure, search bar functionality, and internal linking. Ideal freelancers should have experience in UX design, e-commerce platforms, and mobile optimization. Please share your relevant expertise and approach to enhancing these elements.

I’m building a mobile experience that lets a user pick a picture from their gallery and instantly discover who’s in it and how they feel. Think of Sherlock-style intelligence focused on faces and emotions, but built natively for Android first, with a clean, modern interface that will later scale to iOS. Here is the flow I need implemented end-to-end. A user opens the app, chooses a photo stored on the device, the image is uploaded securely to the cloud, an AI model analyses faces, detects their emotions, and returns the findings in seconds. Results should appear in an elegant card-based UI that feels at home on recent Material guidelines. All design work, backend APIs, AI model integration, security (encryption in transit and at rest), and Play-Store-ready build...

I have an existing site that works, but its look and feel are dated and the navigation is clunky. My top priority is to elevate the user experience—every decision should make it easier and faster for visitors to reach the content or products they came for. Visually, I’m drawn to current, clean design trends: generous white space, crisp typography, subtle animation where it adds value, and imagery that feels fresh rather than stock-y. Consistent branding is important, yet I’m open to creative approaches that keep the site recognizable while giving it a polished, contemporary edge. Key objectives • Streamline page layout and menu structure so users intuitively know where to click next. • Deliver fully responsive templates that look great from mobile...

...concept, I’ll rely on you for the hard, production-level details. That means accurate dimensions, material call-outs, seam construction, filling requirements, safety notes, color references, and clear labeling—everything a manufacturer can pick up and quote without further clarification. CAD drawings, exploded views, and high-resolution renders should accompany the tech pack so we can validate ergonomics and appearance before sampling. Deliverables • Finalised design files (Ai, CAD or similar) for both the bed and toy • Complete spec sheets / tech packs ready for factory hand-off • Print-ready graphics or embroidery files if the design calls for them • A brief hand-over document explaining measurements and material choices If you have e...

...CAD/SketchUp/Revit source files for all approved areas Material, finish, and hardware schedules with model specifications One revision cycle per space to incorporate feedback Annotated walkthrough or brief video explanation for each design package Acceptance Criteria All drawings must be to scale and fully coordinated with plumbing, electrical, and structural constraints where applicable. Clearances, ergonomics, and installation feasibility must be verified. The design should demonstrate a consistent modern aesthetic, efficient storage planning, and well-resolved functional layouts, supported by clear design reasoning. If you are available to manage multiple detailed design packages and can provide feedback revisions within a few days, please share your availability so we can a...

I need a clean, web-based dashboard that focuses exclusively on user analytics, with special attention to engagement metrics. The goal is to let me open one screen and instantly understand how users interact with my product over time. Key requirements • Metrics: Any engagement-related figures I feed in (e.g., sessions per user, session duration, retention day-N) must be visualised. • Visuals: Line charts are the primary format so trends can be spotted at a glance. • Interactivity: Filters for date ranges and user segments will help me drill down quickly. • Tech stack: I’m flexible—Tableau, Power BI, Looker Studio, Plotly/Dash, or a lightweight React + D3 setup all work for me, as long as the final result is responsive and easy t...

Project Software testing using AI tools for the user interface. We require testing on the user side, which encompasses all modules: registration, posting deals, posting requests, request notifications, responding to offers, and testing filters for each category and subcategory. We need detailed bug reporting, preferably with screenshots or videos if necessary. However, a screenshot accompanied by text and a text file explaining the bug is essential. Please provide a demonstration of a bug on the user side and submit a bid based on the number of bugs you will report. A bug is not limited to textual errors; it can include any functional issue that is not operating correctly: incorrect expected results, broken links, email or data mismatches, incorrect results displaye...

I have just provisioned a fresh Linux-based VPS that runs Apache and I need my existing website—files, database, and all configuration—moved over seamlessly. Your task is to replicate the current production environment on the new server, point the domain once everything checks out, and make sure the site is fully functional after the switch. Here is what I expect to receive at the end of the engagement: • All site files copied to the VPS with correct ownership and permissions • Database exported, imported, and linked to the application • Apache virtual host configured, SSL certificates (if any) reinstated, and relevant PHP modules enabled • Any hard-coded paths or connection strings updated • A brief hand-off note outlining what you change...

...someone to fully test the user side of from a computer and a mobile phone. is a college search and comparison website. I need a careful person to use the website like a real user and report anything that does not work correctly. This is not a complex technical task, but it requires patience, attention to detail, and real human testing. Important: This must be real human testing. Please do not use AI to generate a generic website review. I need you to personally open , click through the website, create a user account, test the filters one by one, test from PC and mobile, and report real issues with screenshots. I do not want an AI-written report. I want real manual testing from a real person using the website like a normal user. Website to test: CampusP...

I have an existing prototype in Figma that you can preview here: I’m looking for a complete overhaul—nothing less—of the current user dashboard.

I need a complete, scenario-driven end-user manual for my financial platform that guides an intermediate user through every core workflow. Each step must include annotated, high-resolution screenshots so a reader can follow the exact sequence without confusion. Because the audience already understands basic fintech concepts, the writing should skip elementary explanations and instead focus on the platform’s specific screens, options, tips, and potential pitfalls an intermediate user might meet. Tone must stay friendly, concise, and action-oriented. I’m flexible on final format—PDF, Word, or an online page all work—so long as the file is easy to update later. Feel free to suggest the structure you prefer. Deliverables • A fully format...

...now need them brought to life as photorealistic interior visualizations. The goal is to help the client and medical staff clearly picture the finished space before build-out begins, so accuracy to the CAD plans is essential. Scope • Transform my existing DWG files into a clean 3D model. • Apply authentic materials, furnishings and medical-grade fixtures that respect healthcare regulations and ergonomics. • Produce high-resolution still renders of all key zones—reception, consultation rooms, treatment areas, corridors and any ancillary spaces shown in the plans. • Optional (quote separately if you wish): short fly-through animation or 360° panoramic views for interactive presentation. Tools Feel free to work in 3ds Max, SketchUp + V-Ray, Blender + C...

I need a developer to add a dedicated statistics page to my existing application that focuses exclusively on user engagement metrics. The data is already available through our backend endpoints; your job is to fetch it on the client, process it if needed, and present it clearly. Core scope • Build a new page or route in our current code-base that queries the user-engagement API I will provide. • Display key engagement numbers—think active users, session length, retention, etc.—in clean, responsive components. • Integrate at least one interactive chart (I’m open to line, bar, pie, or any library you prefer such as recharts, , or nivo) so the data is easy to digest. • Keep the page consistent with our existing Tailwind styling an...

...notes into precise geometry that will hold up in real-world manufacturing. The scope includes building complete assemblies with proper tolerances, optimizing each part for strength and printability, and supplying all native Fusion 360 files alongside the usual export formats—STL, STEP, and OBJ—so I can move straight to 3D printing or CNC machining. I may ask for iterative tweaks as we refine ergonomics or aesthetics, so please factor in timely revisions and clear communication throughout the development phase. If you have a portfolio of Fusion 360 work that shows complex surface modelling, functional mechanisms, or past product prototypes, let’s talk and schedule our first design session. Responsibilities Create accurate 3D models and assemblies using Autodes...

I have an Android app concept ready to move from wireframes to working code, and the first milestone is a solid, secure user-authentication flow. The job is to create a native Android application where new users can sign up, existing users log in, and forgotten passwords are recovered. Social sign-in (Google, Facebook, email/password) would be an added bonus if you’re comfortable wiring it up with Firebase Authentication, AWS Cognito, or another reliable backend. The design assets and basic screen sequence are finished; what’s missing is production-quality code that follows current Android guidelines, runs smoothly from Android 8 upward, and is easy to maintain. Kotlin or Java are both acceptable—just keep the project cleanly structured (MVVM preferred) and well d...

I need a single, fully responsive user-login screen coded from scratch with clean HTML5 and CSS3. The form will ask only for username / email and password, then post to a placeholder action I can swap later. Aside from my logo and colour palette—which I’ll send once we start—you are free to shape the visual style so it feels modern, lightweight, and accessible. Key points • Fluid layout that reads well from 320 px mobile up to large desktop, using percentage widths and media queries. • Semantic tags, labelled inputs, and ARIA attributes so screen-readers announce everything correctly. • Organized stylesheet (custom properties or SCSS compiled to CSS is fine) with comments showing the breakpoints you chose. • Built-in client-side validat...

...existing site so visitors no longer struggle to find the information they need. Improving the overall user experience is the single priority; the aesthetic look and new feature requests can wait until the menu structure feels effortless on both desktop and mobile. Right now, the navigation is bloated and scattered, and users report that locating key pages takes too many clicks. I want a cleaner, well-labeled hierarchy that surfaces our most-visited content quickly, trims or combines redundant menu items, and performs smoothly across all screen sizes. Fast load times must be preserved while we restructure. Deliverables • Brief UX audit summarising current pain points backed by analytics or quick user tests • Proposed information architecture: revised sitemap, ...

What will win you the job • Clear examples of past accessibility projects. • Familiarity with modern frameworks (React, Angular, Vue, or similar) or CMSs. • A realistic timeline that fits within my internal release schedule. ...

I’m rolling out a referral push for and need 100 live, well-placed posts across Facebook groups, WordPress forums, and other technical communities. Every post will carry a unique referral code I assign so I can trace new sign-ups back to your work. The core metric is user registrations—traffic and awareness are helpful, but the bonus kicks in only when your code drives real accounts. Here’s what I expect: • 100 promotional-style posts that fit naturally within each community’s rules and tone. • A simple tracker (spreadsheet or shared doc) with the post URL or screenshot, date, and the referral code used. • Ongoing updates so I can match registrations against your list and release performance bonuses promptly. When you apply, send m...

I need a straightforward website for my brand, Fahrijsbabakam, whose core feature is a secure user-login system. No store, blog, or extra modules for now—just a clean public landing page and a private area that appears once someone signs in. Here’s what I expect: • Responsive front end styled with my brand colors and logo placeholder. • Registration, email verification, password reset, and standard security practices. • Simple dashboard page visible only to authenticated users. • Lightweight admin panel where I can view, edit, or delete user accounts. • Complete source code, clear setup instructions, and a brief handover call.

My app already handles sign-in with username and password and stores everything in a relational database (MySQL/PostgreSQL). I have three tables: • users • doctors What I need now is the logic that, immediately after a successful login, returns only the doctors connected to that specific user. The same rule must apply to every page, API endpoint, or query that surfaces doctor data, so a user never sees records that aren’t theirs. 1. Adjust the current queries or create a middleware/service layer that filters by user_id from the session/token. 2. Provide clear comments or brief documentation so I can extend the filter when I add new roles. 3. Deliver tested code (SQL statements, ORM scope, or framework middleware—whichever fits) that plu...

...pot should dictate motor speed; the instant the button is released the output must drop to the same state as an e-stop, guaranteeing zero drive. The housing has to be fully 3D printable on a typical FDM printer (200 × 200 × 200 mm envelope, PLA or PET-G). Ergonomics matter—I’m picturing something that can be gripped like a bicycle throttle with the thumb naturally resting on the kill switch—but feel free to propose alternatives if they remain compact and printable without supports in awkward internal cavities. I’m an advanced Arduino user, so focus on solid electronics and mechanical design rather than step-by-step tutorials. I still expect well-commented code and clearly labeled schematics so I can integrate the unit straight into m...

...PHP-based dashboards dedicated to user management. Each screen should stay true to a modern, minimalistic aesthetic while still offering intermediate-level insight—simple graphs for at-a-glance trends and clear activity logs that let an admin quickly understand who did what and when. The core idea is speed and simplicity: clean PHP templates, concise HTML/CSS, and a small JavaScript chart library (, ApexCharts or similar) to power the visualizations. I do not need a full framework or anything heavy; vanilla PHP with Bootstrap-level styling is ideal as long as the pages remain lean and responsive on desktop and mobile. Deliverables • Dashboard 1: overview panel showing user counts, role distribution and a compact activity feed. • Dashboard 2: detailed ...
