À propos de ce service

Is your web app throwing console errors, failing build pipelines, or running slow? A single broken function or unhandled promise can ruin user experience and cost you customers.

As a FullStack Engineer with 5+ years of experience, I specialise in rapid troubleshooting, root-cause analysis, and clean refactoring across the JavaScript & TypeScript ecosystems.

What I Fix & Optimise:

  • Frontend: React re-rendering bugs, state management glitches (Redux/Zustand), CSS/Tailwind layouts, and Next.js hydration errors.
  • Backend & APIs: Express/NestJS crash errors, unhandled async exceptions, broken REST/GraphQL endpoints, and CORS issues.
  • Database & Speed: Slow PostgreSQL/MongoDB queries, memory leaks, and server performance bottlenecks.
  • Builds & Dependencies: Node module conflicts, TypeScript errors, Webpack/Vite configs, and broken CI/CD builds.

Why Choose Me?

  • Clean Solutions: I fix the root cause, not just the symptom, so bugs don't return.
  • Safe Delivery: Branching techniques to ensure zero disruption to live users.
  • Clear Updates: Detailed breakdowns of what caused the issue and how it was fixed.

Send me a message with your error details, or place an order to get it fixed today!
