Custom Web & Mobile Application – Automatic Construction & Renovation Price Calculator

@infowider11

Hello, How are you? I can build a fully custom, scalable web + mobile application for automated construction pricing, with complex business rules, dynamic multi-step forms, and multilingual offer generation (RO/EN from day one). I recommend React (Web) + Flutter or React Native (Android/iOS) with a Node.js/NestJS backend and PostgreSQL, ensuring shared logic, clean APIs, and long-term scalability across countries. The pricing engine will be rule-based and configurable from an admin panel (coefficients, formulas, descriptions, localisation), allowing non-technical updates without code changes. Deliverables include PDF price offers, REST APIs, role-based admin tools, and a modular architecture ready for SaaS expansion. Let’s chat.. Thanks

Hi There, 1.I am looking for an experienced Full-Stack Developer to build a custom we... ==> We got the idea about the custom-built application with complex pricing logic for construction projects. We have done similar types of projects in the past. I recall working on a system for a different industry where users could select service components, and it would not only calculate the price but also suggest optimal package deals in real-time to maximize value. We understand the need for dynamic multi-step forms that change based on user answers. We will build a strong admin panel so you can easily manage prices, rules, and work descriptions for different languages. For the mobile apps, we suggest using Flutter because it allows us to build for both Android and iOS from one codebase, which is efficient. ## Queries : 1. How should the system handle a users selection of services that might be technically conflicting or require a special review before a price can be generated? ## Initial Project Structure : - Login/Signup - Project Type Selection - Dynamic Questionnaire - Offer Summary - Saved Projects - Admin Dashboard - Manage Prices & Rules - Profile Settings We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

Having read your project description thoroughly, it's apparent that my expertise in mobile and web development marries seamlessly with the required skills for this project. With an excellent grasp in MySQL and React Native and familiarity in Violet framework among others, I am confident to build your desired application. On the multilingual aspect, I have the i18n knowledge to guarantee seamless functioning in Romanian and English as you require. My career has seen me successfully create intricate and dynamic forms as well as implementing databases designs- all elements important in achieving your goal. My appreciation of the importance of scalable architecture is a great asset for our potential long-term collaboration. The fact that I am already acquainted with the nuances of pricing algorithms will definitely save us time as we tackle this complex task. Lastly, but importantly, I share your vision of a long-term professional partnership rather than a one-time delivery. As such, committing to maintaining the platform; tweaking features to adapt to other countries like Italy, Spain, Germany, France; and continuously improving it is not an issue. I can assure you the quality of my work will remain unwavering throughout our engagement since I am on a mission to redefine software services on freelancer platforms -starting with your project!

Hi, this is Elias from Miami. I’ve checked the project description and I understand you need a custom web + mobile app (Web, iOS, Android) that generates construction/renovation price offers using dynamic multi-step forms, conditional fields, and solid pricing rules (city, floors, surfaces, complexity, selected works). This is a real configurator, not a template site, so the logic + admin controls matter most. I’ve built similar rule-based calculators and SaaS dashboards where admins manage pricing tables, coefficients, and descriptions, and users get instant offers with clean PDFs. I’m also good with multilingual generation (RO/EN) so every offer + work description comes out correctly in the selected language. Suggested stack (clean and scalable): React (web) + React Native (iOS/Android) or Flutter, Node.js/NestJS or Laravel API, PostgreSQL, i18n, and PDF offer generation. Q1: For pricing rules, do you want a “formula builder” style (rules engine) in admin, or is it fine to manage structured tables (base price + coefficients per city/type/work)? Q2: Should offers be saved as a versioned quote (so later price changes don’t affect old offers), and do you need a public share link for clients? Q3: For the dynamic forms, will you provide the full field list + conditions per project type, or should I help you model that into a configurable schema in the admin? Regards, Elias

Hello, I’ve read your description carefully, and this is exactly the kind of custom, logic-heavy platform I specialize in. This is clearly not a CMS or template job—it’s a full-fledged pricing engine wrapped in a web and mobile application, and that’s where my experience fits very well. I’m a full-stack developer with 8+ years of experience building custom SaaS platforms, configurators, calculators, and business-rule–driven applications for web and mobile. I’ve worked extensively on systems where pricing depends on multiple variables such as location, surface area, complexity, coefficients, and conditional selections, and where outputs must be generated dynamically in multiple languages. For this project, I would architect a clean, scalable system where the pricing logic lives centrally in the backend, exposed via secure REST APIs. This ensures the same logic is reused across Web, Android, and iOS without duplication or inconsistencies. On the frontend, I’d implement multi-step dynamic forms with conditional fields that react instantly to user choices, keeping the experience intuitive even though the logic underneath is complex. Looking forward to discussing the technical details, timeline, and next steps.

@agilifytechllc

Hi Claudiu G., I will transform your complex construction pricing logic into a high-performance, cross-platform engine that delivers instant, multi-language quotes with surgical precision. The Architectural Strategy: The "Engine & Shell" Approach To meet the requirement for Web, Android, and iOS while maintaining a complex pricing algorithm, I propose a shared-logic architecture that ensures "write once, calculate everywhere" reliability. --> I will build a headless pricing engine using Node.js (TypeScript) or Python. --> I will utilize React (Web) and React Native (Mobile) to share up to 80% of the codebase. --> A PostgreSQL database will store the relational hierarchy of construction works. --> Integration of a server-side PDF engine (Puppeteer or PDFKit) to generate professional. Are your coefficients additive (fixed price per sqm) or multiplicative (complexity scores that increase the total by a percentage), and do we need to handle "Formula Overrides" for specific premium materials? For the Mobile apps, do users need the ability to generate quotes while on-site without an internet connection, or will the app always rely on the live REST API for the latest prices? When an admin updates prices in the panel, should it affect active quotes in progress, or do we need to "version" the prices so older quotes remain valid for a specific period? Regards, Atta
