I build systems for environments where complexity is real.

An agent can change code without being able to publish or deploy it. Authority is split before anything runs.

One owner leases the work and every attempt is recorded, so retries and interruptions can be explained afterwards.

Retries, dead-letter queues and idempotent consumers are part of the first design, not a fix after an incident.

In healthcare, the backend owns identity and hands the browser credentials that expire.

Expensive work runs through a queue with explicit CPU and GPU limits, so the product stays responsive under load.

A change is finished when its checks pass, not when it compiles. Unit and end-to-end tests run in CI before work reaches review.
