Services - API Design & Development

We design and build production-grade REST APIs with clear documentation, predictable behavior, and developer experience that doesn't require a phone call to understand.

Overview

A poorly designed API is a tax on every team that touches it. Inconsistent responses, undocumented edge cases, authentication that works until it doesn't — these things compound. Every new feature costs more than it should because the foundation wasn't built with the long view in mind.

We design APIs the way we'd want to consume them. Clear endpoint structure, typed request and response shapes, predictable error semantics, and documentation that tells you what you actually need to know.

What we build

  • REST API Design & Architecture
  • Authentication & Authorization (JWT / Bearer)
  • CRUD & Lifecycle Endpoints
  • Webhook Systems
  • Rate Limiting & Security
  • Interactive API Documentation

How we approach it

We start with the contract — what the API needs to expose, what it needs to protect, and how consumers will interact with it. Architecture decisions get made before code gets written, not discovered halfway through.

We build on Node.js and Express, deployed to Google Cloud, with Firebase for data persistence where it fits. Every API we deliver includes full documentation and, where appropriate, an interactive playground so your team or clients can explore it without writing a line of code.

What to expect

  • Contract-first design
  • Full endpoint documentation
  • Auth, error handling & edge cases covered
  • Interactive playground available
