Microservices-Ready API Platform

Context / problem

As client applications multiplied, the backend needed clearer ownership boundaries and safer evolution. The goal was pragmatic decomposition: services where it earned its keep, not microservices for aesthetics.

What I built

• Versioned REST endpoints with stable error semantics
• Clear module boundaries and shared kernel discipline
• Integration testing hooks for contract-sensitive endpoints
• Operational patterns for rolling releases and safe rollbacks

Tech stack

Architecture

Core domains stay cohesive; cross-cutting concerns are handled with explicit interfaces. Async work crosses boundaries via queues/events where synchronous coupling would create scaling ceilings or cascading failures.

Impact

Faster iteration with fewer surprise regressions; teams could ship client features without constantly negotiating hidden shared state.
