About this gig
Are you facing bugs, errors, or unexpected issues in your application? Whether it's a frontend, backend, API, database, or deployment problem, I'm here to help.
I'm a Full-Stack Developer experienced in debugging and fixing issues across different technologies. I'll identify the root cause, explain the problem if needed, and provide a clean, reliable fix without affecting existing functionality.
I can help with:
- Frontend bugs (React, Next.js, HTML, CSS, JavaScript, TypeScript)

- API issues (REST APIs, authentication, third-party integrations, CORS)
- Database problems (MongoDB, MySQL, PostgreSQL, SQLite, Firebase)
- Deployment and server errors
- Performance, logic, runtime, and debugging issues
Why work with me?
- Root cause analysis instead of temporary fixes
- Clean, maintainable code
- Clear communication and regular updates

FAQ
What do you need to start working on the bug?
I will need a brief description of the issue, screenshots or error logs from the browser console/terminal, and access to your source code (via a GitHub repository or a zip file).
Can you fix bugs in a live/production environment?
To ensure absolute safety, I prefer working on a local clone or development environment first. Once the fix is verified and tested, we can securely deploy it to your live production server.
Do you offer express 24-hour delivery for all packages?
Yes! For Basic and Standard bugs, I target a strict 24-hour delivery as highlighted on my gig banner. For highly complex or multi-layered premium issues, we can mutually discuss the exact timeline.
What if the bug returns after the order is delivered?
I offer post-delivery support to ensure the specific issue I fixed stays resolved. If it's an edge case related to my fix, I will happily look into it and resolve it for you.
