About this gig
Are you a vibe coder who built something with ChatGPT, Cursor, Copilot, or Claude but now it's broken and you're not sure why?
You're not alone. AI tools are incredible for generating code fast, but they don't always get it right. That's where I come in.
I'm a senior backend engineer with 7+ years of experience in Node.js, Java, and Spring Boot. I specialise in debugging and fixing exactly the kind of code that AI tools produce subtle logic errors, async issues, broken APIs, and runtime crashes that are hard to spot if you're not deeply technical.
I can fix:
What I need from you:
What you'll get:
Whether you're a founder, a designer, or just someone learning to code with AI I'll get your project unstuck fast. Let's ship it!

FAQ
Do you fix bugs in both Node.js and Java?
Yes! I work with both Node.js (Express, NestJS, Fastify) and Java (Spring Boot, plain Java). Just share your code and describe the issue.
What information do you need to start fixing my bug?
Please share your code (GitHub link or zip file), a clear description of the bug, any error messages or logs, and the steps to reproduce it. The more detail, the faster I can fix it.
Will I receive the fixed code or just an explanation?
You will receive the fully fixed, working code along with a clear explanation of what was causing the bug and exactly what I changed to resolve it.
Can you help if the bug is in an existing large codebase?
Absolutely. I regularly work with existing production codebases. Share the relevant files or repo access and describe the issue. I will navigate the code and isolate the bug efficiently.
