Monitoramento de Desempenho de Aplicações Jobs

I'm looking for an expert to optimize the performance of my web application. Key focus areas include: - Application performance enhancement - Resolving specific performance issues (to be discussed) Ideal skills and experience: - Proven track record in web app performance optimization - Expertise in identifying and resolving slow loading times, high memory usage, and crashes - Strong knowledge of web technologies and optimization tools - Ability to analyze and improve application performance metrics Please provide relevant experience and approach in your bids.

I’m looking for a specialist who can carry out end-to-end performance testing directly against our live production site. The goal is to reveal how the application behaves under real-world load, identify breakpoints under extreme stress, and confirm that it scales smoothly when traffic grows. Here is what I need from you: • Design and execute load, stress and scalability tests that reflect our current usage patterns as well as projected peaks. • Leverage industry-standard tooling—JMeter, Gatling, k6, or a comparable solution you’re comfortable with—and document every configuration so results can be reproduced later. • Monitor key metrics in real time (response times, error rates, CPU / memory / I/O, database throughput) and capture them in easily...

I’m adding a dedicated Bill of Lading module to my React Native application and I want every shipment’s status to be visible the moment it changes. The core of the job is wiring the app to the provider’s API so that users on both iOS and Android can: • see real-time status updates the second they are posted • receive in-app and push notifications for each status change • review a full historical timeline for every Bill of Lading You’ll design the data flow, connect the REST/WebSocket endpoints, build the UI screens, and make sure the new code plays nicely with the existing Redux store and TypeScript setup. Proper error handling, offline caching, and unit tests are expected so I can ship to TestFlight and Google Play without surprises. **Relevan...

I need a lightweight Windows-only .exe that lets me draw directly on the screen while any application is running. The main interface can be a slim sidebar with the classic whiteboard controls—pen (with adjustable size and colour), highlighter, eraser, hand/pan tool, plus undo and redo. Two extra features round it out: • An Import button so I can pull external files straight onto the canvas. I’m open to whichever formats are easiest to implement first; images and PDFs would cover most of my use cases, and we can expand later if it’s straightforward. • A built-in “Open Browser” command. I just need a full browser window to appear inside the app; I haven’t fixed on Chrome, Edge, or Firefox, so use whichever engine integrates cleanly and kee...

I already have a working desktop budget-management application and now I’m ready to extend its capabilities. My priority is to add new features rather than fix bugs or work on performance tuning, so I need someone who enjoys feature development and can plug into an existing codebase quickly. The current build is stable and fully documented; you will receive the repository and a brief walkthrough of its architecture at the start of the engagement. From there, we’ll outline the features in detail together—think smarter reporting views, additional expense categories, maybe a quick-export to CSV/PDF—then agree on a milestone plan so you can deliver iterative updates and I can test on my side. Deliverables (per milestone) • Updated source with the agreed fea...

I’m looking to build a desktop-only application whose core mission is simple: help me mengelola Microsoft files and related assets through a streamlined document-management workflow. Think of a lightweight, Windows-friendly tool that can import Word, Excel, PowerPoint, and PDF files, let me tag and categorise them, search quickly, preview in-app, and keep basic version history so I never lose track of edits. Here’s what matters most to me: • A clean, intuitive interface that feels native on Windows. • Fast indexing and search to surface any document in seconds. • Folder and tag management so I can group files by project or client. • Basic permission control or password lock for sensitive documents. • Export/backup options to standard formats or cloud f...

I built the entire application on Base44 and it works, but the code has grown a little wild. I now want a thorough refactor that sharpens performance and, above all, shaves every unnecessary millisecond off response time. There are no crashes or memory spikes at the moment; this is a proactive tune-up so the app stays snappy as traffic grows. You’ll be free to reorganize modules, streamline functions, remove duplication, and apply best-practice patterns that make future maintenance painless—all while respecting Base44’s conventions. I’d also like any heavy assets minified or lazy-loaded where sensible, database queries reviewed for efficiency, and a concise report that highlights which changes delivered the greatest speed gains. Deliverables • Clean, well-s...

I need a lightweight manual dialer that runs smoothly on Windows and faithfully records every call I make. The core requirement is simple: I enter a number, hit dial, and the application logs key details—number dialed, start & end time, and call outcome—into a clear, exportable file (CSV or similar). While contact management or speed-dial shortcuts might be nice down the road, for this first release I only want reliable call-logging baked in. Feel free to build in a modular way so extra features can be bolted on later without a full rewrite. Deliverable: a Windows-ready installer (or portable EXE) plus clean, well-commented source code and a quick read-me that shows me how to configure, run, and access the log. I’ll test by placing 10 sample calls; if all appear...
