FAQ
What do you need from me to get started?
I typically need access to your source code repository (GitHub, GitLab, or Bitbucket). If the issue is related to a live server, I may need SSH access or environment variables (.env) to reproduce and fix the bug.
Can you fix deployment issues on Nginx, Docker, or Gunicorn?
Yes! I have extensive experience deploying Django and Next.js applications. I can troubleshoot 502 Bad Gateway errors, configure Gunicorn/Uvicorn, set up Docker containers, and ensure your Nginx reverse proxy is working correctly.
Do you work on existing or legacy codebases?
Absolutely. A large part of my service involves reviewing existing code written by other developers. I can audit the code, fix logic errors, and refactor it to meet modern standards without breaking current functionality.
My website is slow. How much can you improve the speed?
I focus on tangible results. For Next.js, I optimize images, fonts, and hydration processes. For Django, I optimize database queries (N+1 problems) and implement caching (Redis). I aim to significantly improve your Google PageSpeed Insights score.
Do you offer long-term maintenance after the gig is over?
Yes, I offer monthly maintenance packages. This includes regular library updates, security patches, and monitoring to ensure your app stays online and secure. Please message me for a custom maintenance quote.
How soon will I see the results after you finish?
Instantly. As soon as I deploy the fix, your bug will be resolved. For speed optimizations, you will see higher PageSpeed scores and faster load times immediately after the update goes live.
