What I do?

Architecture and APIs

Service boundaries, explicit contracts, and failures that do not fail quietly.

Data modeling and processing

Entities with stable identity, queries an analyst can audit, idempotent pipelines.

Automation and internal tools

Repeatable work becomes a job with a contract, not a spreadsheet one person understands.

Reproducible environments

Docker, tests, and a README that brings the system up without theatre.

Documentation and decisions

Short ADRs: what was chosen, what was refused, what it costs.

Open to selected opportunities

I work where business rules meet storage and API contracts. Python and SQL are the medium; the product is a system another engineer can operate.
