Backend & API development

Backend & API development services

We design and build the server side that products depend on: REST APIs, authentication, databases, payments, background jobs and real-time features - with Node.js, Express and NestJS in TypeScript.

Our backends power our own POS platform processing live restaurant orders every day, so reliability isn't a slide in a pitch deck - it's how we already operate.

What we deliver

What's included in our backend & api development

REST APIs & microservices

Well-documented, versioned APIs with validation, rate limiting and role-based access control.

Authentication & licensing

JWT/session auth, SSO, API keys and license issuance - the same patterns behind POSflow's own licensing system.

Data & integrations

PostgreSQL schema design, migrations, and integrations with payments, accounting, delivery and messaging platforms.

Real-time & background work

WebSockets for live updates (like kitchen displays), plus queues and scheduled jobs for heavy processing.

FAQ

Frequently asked questions

Node.js with TypeScript - NestJS for structured, larger systems and Express for lean services - with PostgreSQL as the primary database and Redis for caching and queues.

Yes. We regularly build or extend APIs for existing web and mobile frontends, including documenting them (OpenAPI) so your team can work against them confidently.

Input validation, parameterised queries, hashed credentials, rate limiting, least-privilege access and secrets kept out of the codebase - plus authenticated, auditable admin surfaces.

Yes - schema design, indexing for real query patterns, and versioned migrations so the database evolves safely with the product.

We build stateless services behind a load-balancer-friendly design, with caching and queues where they matter - so scaling is a deployment decision, not a rewrite.
