- i build and maintain production backend services and API integrations, including authentication, credential lifecycles and transaction synchronization. much of the work is making sure an interrupted sync can pick up safely: durable checkpoints, idempotency, bounded retries and recovery when a provider fails.
- i work on PostgreSQL models and transactional workflows, with migrations, integrity constraints and regression tests around critical paths. for asynchronous workers, that means leases, queue deduplication, concurrency controls and enough structured observability to understand a failure.
- i also work on CI/CD: GitHub Actions and Docker for tests, type checks and builds, followed by staging and deployment workflows on AWS.
