Backend and REST API development

We design and build the server side of your product: REST APIs, database schemas, authentication, payments and the connections to the third-party services you rely on.

Our backend lead works across Laravel, NestJS, FastAPI and Spring Boot, with PostgreSQL, Redis and Kafka underneath, so we choose the framework that fits your project and your team instead of forcing one.

  • Laravel
  • NestJS
  • FastAPI
  • Spring Boot
Scope

What's included.

In scope

  • REST API design and implementation, with documentation
  • Database design, mainly on PostgreSQL
  • Authentication and user roles
  • Payment and third-party service integrations
  • Caching and background queues with Redis and Kafka
  • Microservice architectures when a product needs independent services
  • One API serving your website, mobile app and desktop app

A good fit for

  • Startups that need an API for a new web or mobile app
  • Businesses connecting systems that do not talk to each other yet
  • Teams whose existing backend needs new features or better performance

FAQ

Common questions.

Which backend framework should my project use?

It depends on your product and your team. Laravel suits many business applications, NestJS fits teams already working in TypeScript, FastAPI works well for Python and data-heavy services, and Spring Boot for Java environments. We recommend one after hearing your requirements.

Do you document the API?

Yes. API documentation is part of every handover, together with setup guides and deployment runbooks, so any engineer can take over.

Can you work on a backend someone else built?

Yes. We review the existing codebase first, then add features, fix bugs or improve performance within it.
