Backend Services & APIs

Your app is only as good as the services behind it. We build the engine room — APIs, data, authentication and infrastructure — so your product stays fast as it grows.

What We Build

The Services That Make Your App Work Efficiently

Whether we built your front end or someone else did, we design backends that are secure, observable and ready to scale — from a single API to a full microservices estate.

  • Data & storage designSQL and NoSQL schemas, caching, search and reporting
  • Authentication & securityOAuth, SSO, role-based access and encryption done properly
  • IntegrationsPayment gateways, ERPs, CRMs and any third-party API

Why Deazitech

Backends With Payment-Switch Pedigree

High-Stakes Experience

We build systems that move money over ISO 8583 — uptime, idempotency and audit trails are second nature, not afterthoughts.

Faster to Production

AI-assisted development and test generation get your API surface built and verified in a fraction of the traditional time.

Built to Be Operated

Logging, metrics, alerts and documentation ship with the code — so the system is maintainable long after launch, by us or by your team.
