Four things, done properly

We take the whole path — architecture, build, deploy, and the on-call rotation after. No hand-off to a team that has never seen the code.

Backend & APIs

Services that stay predictable when traffic is not. Schema-first data models, hard boundaries, and refactors that pay for themselves.

Refactored an enterprise platform down to 50 ms responses.

  • Express
  • FastAPI

  • Redis
