- Implement a clean, tested fix
- Document what went wrong and why
LANGUAGES & FRAMEWORKS
Python, JavaScript, TypeScript, React, Node.js, FastAPI, Django, Express, SQL, PostgreSQL, MongoDB
WHAT YOU GET
- Working fix applied directly to your code
- Root cause explanation so you understand the issue
- Prevention tips to avoid similar bugs
- Commented code so every change is clear
MY PROCESS
1. Analyze your code and reproduce the issue
2. Trace the bug to its exact root cause
3. Implement a clean fix following best practices
4. Test and document everything
I combine deep debugging experience with advanced analysis tools to find issues faster than traditional approaches. From simple logic errors to complex async race conditions, database query bugs, or API integration failures.

FAQ
What details should I provide when placing an order?
The more context, the faster the fix. Please share: (1) description of the bug and expected vs actual behavior, (2) steps to reproduce, (3) relevant code or repo access, (4) any error messages or logs. If you're not sure what's causing it, that's fine — I'll investigate.
What languages and frameworks do you work with?
Python, JavaScript/TypeScript, React, Node.js, FastAPI, Django, Express, PostgreSQL, MySQL, MongoDB, Docker. If your stack isn't listed, message me first — I likely still can help.
What if the bug is more complex than expected?
I'll diagnose it first and let you know. If it requires more work than the selected package, I'll explain what's needed and propose an adjusted scope before proceeding. No surprise charges.
Do you just patch the symptom or fix the root cause?
Root cause, always. A quick patch often creates new bugs down the line. I trace the issue to its source, fix it properly, and explain why it happened so you can prevent similar issues.
Will you test the fix before delivering?
Yes. Every fix is verified before delivery. For Premium packages, I also check for regressions — making sure the fix doesn't break anything else.
