Über diesen Service

Got a bug that's driving you crazy? I'll find the root cause and fix it, fast.


Senior software engineer with 23+ years of experience. I fix React, Next.js, Node.js and JavaScript/TypeScript issues, including:

- React state not updating and re-render bugs

- Next.js hydration mismatch, build and deploy errors

- API 500s and broken fetch/axios calls

- TypeScript type and build errors

- Prisma and database migration issues

- Tailwind and CSS layout bugs

- Performance and memory problems


What you get: a real root-cause fix (not a band-aid), clean explained changes, and direct communication.


How it works: send me your repo link, the exact error message, and minimal steps to reproduce. I diagnose and fix.


Please message me before ordering so I can confirm scope and timeline.

Senior software engineer with 23+ years building enterprise apps, REST APIs, and AI-powered solutions. I specialize in C#/.NET 8, ASP.NET Core, Go, and React/Next.js with TypeScript, plus secure API design and SQL Server optimization. I've built AI speech-to-text pipelines, real-time systems with SignalR, and full-text search platforms, and I ship modern full-stack apps with Stripe, PostgreSQL, and LLM integrations (Claude, OpenAI). Clean, scalable, secure code, on time and on budget. Let's build something great together.
