I debug and fix bugs in Python and JavaScript applications. Whether your backend is throwing 500 errors, your React frontend has rendering issues, or your API integration is broken, I find the root cause and deliver a clean, tested fix.
What I fix:
Python Backend:
- Django: ORM bugs, migration errors, auth issues, REST framework serializers, Celery task failures
- FastAPI: async/await problems, Pydantic validation, dependency injection, CORS
- Flask: routing errors, blueprint issues, database connections, Jinja2 templates
JavaScript Frontend and Backend:
- React: rendering bugs, state management, infinite re-renders, hook issues
- Next.js: SSR/SSG errors, API routes, hydration mismatches, build failures
- Node.js: crashes, memory leaks, async errors, Express middleware
Additional services:
- Web scraping and data extraction (BeautifulSoup, Playwright, Selenium)
- Task automation (file processing, report generation, data pipelines)
- REST API development and integration (Stripe, Twilio, SendGrid)
- Database optimization (PostgreSQL, MySQL, MongoDB, Redis)
How I work:
1. You describe the bug or share the error message
2. I investigate, confirm the scope, and give you a time estimate
3. I deliver a working fix with a clear explanation
I respond within 1 hour and deliver most bug fixes within 24 hours. Message me with your error details for a free assessment.
