Company-wide API gateway

Part API Gateway

A company-wide API gateway written in pure Node.js — authorization, access control, rate limiting, caching and compression — with a middleware layer that accepts custom logic anywhere in the request pipeline.

Context

What the system had to do

Part Software Group’s products needed a single entry point that handled authorization, access control, rate limiting, caching and compression consistently, without forcing every team through a rigid pipeline.

What I built

Decisions and delivery

Designed and implemented the gateway in pure Node.js, without a web framework, to keep the request path lean and fully under control.
Built an extensible middleware layer that lets custom logic be injected at any point of the request pipeline.
Used PostgreSQL and Redis for persistence and caching.

Outcomes

What it delivered

—
