Lead backend engineer for financial and housing services. I design and build event-driven microservices on FastAPI, PostgreSQL (async SQLAlchemy, Alembic) and Kafka: integrations with external APIs (banks, registries), request/poll/retry queues, outbox pattern and idempotent processing, query batching and performance optimization, and a clean layered architecture (service / repository / use case) that the whole team builds on.

    It was a simple project but he worked on it right away and no issues. Very straightforward and I appreciate the prompt response and completion of the project. Seems to know what he's doing. Based on this work I'd be interested in working together again but not sure anything more will be needed.
