FAQ
Do you use TypeScript or JavaScript?
I use TypeScript by default with strict-mode enabled for maximum type safety. If you prefer plain JavaScript, just let me know — I'm flexible.
Can you work from a Figma or design file?
Absolutely! I can translate Figma, Adobe XD, or any other design mockup into a pixel-perfect, responsive React component.
What if I need changes after delivery?
Revisions are included in every package: 2 for Starter, 3 for Business, and unlimited for Enterprise. I'll make sure you're 100% satisfied.
Do you write unit tests for the code?
Yes! Unit tests with Jest and React Testing Library are included in the Enterprise package. For Starter and Business, testing can be added as a paid extra if needed.
