Systems that move data

I work on data infrastructure — ingestion pipelines, ELT connectors, and the internal platforms built around them. Mostly Python and TypeScript, on FastAPI and Django, against Postgres.

Most of what I know about distributed systems came from watching them fail in ways the documentation did not cover: a binlog that rotated mid-read, a schema that gained a column overnight, a CDC cursor that advanced past rows it never delivered. The interesting part of ingestion is never the happy path.

So I build for the unhappy one. Systems that fail loudly, interfaces that are honest about what they do not know, and code the next person can read at 2am.

Outside work: lifting, cars, and an ongoing and probably unreasonable interest in mechanical watches.
