API & Backend Development
APIs, databases, auth, and the plumbing that keeps a product alive at 3am. We design schemas that survive growth, write endpoints that fail loudly instead of silently, and document everything so your next developer isn't lost.
Whether it's the backend for your mobile app, a REST API for partners, or moving off a spreadsheet into a real database — we build production-grade infrastructure without enterprise-grade invoices.
What's included
- REST API design and implementation
- PostgreSQL / Supabase schema design and migrations
- Authentication: OTP, OAuth, role-based access
- Real-time data: subscriptions, webhooks, queues
- Rate limiting, validation, and error handling
- API documentation your team can actually use
Common questions
Can you build the backend for an existing app?
Yes. We regularly build or replace backends behind existing mobile and web frontends — matching your current API contract or designing a cleaner one with a migration path.
Which stack do you use for backends?
PostgreSQL for data, Supabase or Node.js for the API layer, depending on scale and budget. Boring, proven technology that hosts cheaply and hires easily.
Do you handle authentication and security?
Auth (OTP, social login, sessions, roles), input validation, rate limiting, and least-privilege database access are part of every backend we ship — not optional extras.
