I need an experienced .NET and React developer who can give my product a full-time focus—eight hours a day for the next month—while working side-by-side with my lead engineer during Indian Standard Time. The codebase is already in production; our goal over the coming weeks is to tidy up rough edges, harden performance, and keep new issues from sneaking in as we roll out incremental updates. Tech stack you’ll touch daily: ASP.NET Core APIs, a React front end that leans on hooks and functional components, JSON-heavy data exchange, and Azure resources provisioned with Bicep. You’ll be handling pull requests, writing clean commits, and jumping on quick Teams or Slack calls whenever a change needs clarification. Expect a straightforward workflow—branch, code, PR, review—so we can keep momentum without surprises. Also need to work on Virtual machine I’ll measure success by how smoothly the system runs at the end of the month: fewer bugs, faster response times, and code that my team can extend confidently. If your background shows solid, hands-on experience with .NET, React, and cloud-based deployments, please share that when you apply; it’s the single most important factor in my selection. Both independent freelancers and development firms are welcome—as long as you can dedicate one developer exclusively for the full engagement. Looking forward to working together.

Hello! This is exactly the kind of focused, engineering-led engagement I work best in. A month of full-time ownership alongside your lead engineer, improving stability, performance, and delivery quality on a live .NET + React system, is a very clear and achievable objective. How I’d contribute day to day Backend (.NET / Azure) • ASP.NET Core API clean-up and performance hardening • JSON payload optimisation and validation • Bug fixes with test coverage where gaps exist • Azure VM and resource-level improvements (Bicep-aligned) Frontend (React) • Hook-based component refactors where needed • State and rendering performance improvements • UI bug fixes without regressions Workflow & Collaboration • IST-aligned working hours, 8 hours/day • Branch → PR → review discipline with clean commits • Fast clarification via Teams/Slack when needed • Close coordination with your lead engineer Environment • Comfortable working directly on Virtual Machines • Production-safe changes with rollback awareness By the end of the month, you’ll see: • Fewer production issues • Faster, more predictable performance • Cleaner code your team can extend confidently I’ve worked in long-running production systems where reliability and incremental delivery matter more than flashy rewrites, and I’m happy to dedicate one developer exclusively for the full engagement. Let’s connect and review the current priorities so we can lock the first week’s plan immediately. Best regards, Jasmin

I can help you. Since you are using Bicep for provisioning but still relying on Virtual Machines, there is a likely gap in how configuration drift is handled during incremental updates. I will focus on ensuring your Bicep templates and VM state remain synchronized to prevent environment-specific bugs. For the "JSON-heavy" exchange, I’ll audit your ASP.NET Core serialization and React state logic; data-heavy apps often suffer from large payload overhead and unnecessary front-end re-renders that lead to the "rough edges" you mentioned. I will prioritize hardening your API’s error-handling middleware to ensure that unexpected JSON structures don't crash the client-side hooks. My approach centers on stabilizing the bridge between your Azure infrastructure and the functional React components to ensure performance holds under production load.
