API & Backend Development with Node.js, Express & Supabase

A well-built backend is invisible to end users — it's fast, reliable, and handles edge cases without crashing. A poorly built one becomes the source of every bug report, every data inconsistency, and every performance complaint. Solviba builds backend systems and APIs that your frontend and third-party integrations can depend on.

RESTful API Design & Development

We build APIs with Node.js and Express following REST conventions — clean resource naming, consistent response structures, proper HTTP status codes, and versioning from day one. Every endpoint is documented and tested with Postman before it's called in production.

• Authentication with JWT, session tokens, or OAuth flows

• Role-based access control at the middleware and data layers

• Input validation, sanitization, and structured error responses

• Rate limiting and request throttling for public-facing APIs

Supabase & PostgreSQL Integration

For most applications, Supabase is our default backend platform — it gives us a managed PostgreSQL database, built-in authentication, real-time subscriptions, and file storage in one place. We design schemas that are normalized, indexed, and structured for the query patterns your application actually runs — not just the happy path.

Custom Backend Logic with Node.js & Redis

When your business logic goes beyond what a BaaS can handle out of the box, we build custom Node.js services. We use Redis for caching, session storage, and rate limiting. Background jobs, scheduled tasks, and webhook processing are handled through queue systems that don't block your main request cycle.

Third-Party API Integration & Webhooks

We integrate with payment providers, communication APIs, AI services, and external data sources — building reliable client wrappers with error handling, retry logic, and proper secret management. Webhook systems are built to be idempotent and auditable, so external events are processed exactly once and logged.
