I build backend services for a production multi-tenant SaaS platform. Services are decomposed by business domain, own their data, and communicate asynchronously through a message broker, behind a single API gateway that resolves authentication and authorization centrally.

Most of my work sits between services: boundaries and message contracts, tenant isolation enforced at the data-access layer, idempotent consumers, and the asynchronous flows that keep independently deployed services consistent under load. I build the interfaces on top of them too, and I care about clean boundaries, measurable performance, and systems that stay legible as they grow.
