I will fix bugs in your nodejs express or golang backend API
Avish Shiroya
About this gig
Is your backend crashing? APIs throwing 500 errors? Database queries timing out?
Stop digging through Stack Overflow. I am a professional backend engineer specializing in Node.js, Express, and Golang, and I will get your server back online and running efficiently.
What I fix:
- API routing and middleware errors
- PostgreSQL / MongoDB connection issues & query optimization
- Authentication & JWT token bugs
- CORS errors and security vulnerabilities
- Deployment and environment variable configurations
Why hire me? I don't just put a band-aid on bad code. I find the root cause, fix it cleanly, and explain what went wrong so it doesn't happen again.
Message me before ordering so I can review your server logs or codebase first!
