FAQ
What do you need from me to start working on my project?
I will need access to your repository (GitHub/GitLab) or the relevant codebase files, a brief description of the feature or bug, and any environment variables or API keys necessary to run and test the application locally.
Can you work with existing styles and databases?
Yes! I specialize in React, Tailwind CSS, and relational databases like PostgreSQL. I will make sure any new code or database queries adapt perfectly to your existing architecture and design system.
Do you offer support if something breaks after deployment?
Absolutely. I make sure everything works locally and on your staging environment. If any bugs or unexpected behavior appear directly related to the feature I implemented, I will resolve them promptly.
