Do you build backends for mobile apps?

Yes. We design JSON APIs and authentication flows consumed by iOS, Android, or cross-platform clients.

Which database do you recommend for new products?

PostgreSQL is our default for relational data: strong consistency, JSON support, and mature hosting on Supabase, Neon, or managed cloud providers.

Can you migrate off WordPress or Firebase?

Yes. We plan data export, schema mapping, redirect strategy, and phased cutover to minimize downtime.

How do you secure backend APIs?

We apply input validation, parameterized queries, HTTPS-only cookies, hashed credentials, least-privilege database roles, and security headers on every deployment.
