Frequently asked questions

What's your stack for web apps?

Next.js and TypeScript on the frontend, with Node.js, Convex, or Supabase on the backend depending on the project's data and auth needs.

Can you work with our existing design or codebase?

Yes. I can build from Figma designs or an existing design system, and can join an existing codebase rather than starting from scratch.

Do you handle hosting and deployment?

Yes. I set up deployment, environment configuration, and monitoring on platforms like Vercel so the app is production-ready at launch.

Need a web app built?

Send your requirements and I will provide a scoped execution plan.
