About this gig
I have debugged and fixed production issues across 20+ real SaaS platforms, from Next.js hydration errors to NestJS API failures to PostgreSQL query bottlenecks. Send me your bug, and I'll fix it fast.
What I can fix:
- Next.js: hydration errors, SSR/SSG issues, API route failures, build errors
- NestJS: dependency injection issues, middleware problems, WebSocket bugs
- React: state management issues, hook problems, rendering bugs
- Node.js / Express: API failures, authentication issues, memory leaks
- Database: slow queries, Prisma ORM issues, MongoDB/PostgreSQL bugs
- Deployment: Vercel build failures, Docker config issues, environment errors
- TypeScript: type errors, interface mismatches, generic type issues
How it works:
- You share the bug details or repo access
- I analyze the issue and confirm it's within scope
- I fix it, test it, and explain the solution
- You receive clean, working code with comments
Tech stack I work in:
Next.js · NestJS · React · Node.js · TypeScript · PostgreSQL · MongoDB · Prisma · Redis · Docker

I extract structured data from any website on the internet: static pages, JavaScript-heavy apps, Cloudflare-protected targets, and build the AI-powered product that runs on top of it. In 4+ years, I've shipped 40+ production projects: autonomous scraping pipelines covering 1,800+ websites, multi-tenant AI voice SaaS, full-stack marketplaces, React Native mobile apps, and LangChain AI automation systems. Most freelancers offer one side. I deliver both: data extraction and the full product built around it. Message me before ordering. I'll give you an honest timeline before you spend a dollar.

FAQ
How do I share my bug with you?
Send me the error message or screenshot and describe what went wrong. Repo access helps, but isn't required; screenshots and code snippets work too. I'll review it before you order.
What if you can't fix my bug?
I always review the issue before you pay. If it's out of scope or I can't fix it, I'll tell you upfront and suggest next steps. I won't take your money for something I can't deliver.
Can you fix NestJS backend bugs?
Yes. I've built and fixed NestJS backends across 10+ production SaaS apps, dependency injection, guards, interceptors, WebSocket failures, and Bull queue errors. It's my daily stack.
Do you fix deployment and build errors too?
Yes, Vercel build failures, Docker issues, GitHub Actions errors, PM2 crashes, and Nginx problems. If it's breaking your deployment pipeline, I can fix it.
Will I understand what was fixed?
Always. Every fix includes code comments explaining the bug and what changed. I also send a short written summary so you know exactly what happened and how to prevent it.
