Backend/systems/data engineer. Some notable projects include: - OLAP service for US census data (Rust + Clickhouse) - SQL query metadata extractor and pipeline (Rust + Python) - Bioinformatics pipeline (Python -> Rust)

Most comfortable working in Rust or better-C languages (Zig, etc), where efficient usage of resources is a priority.

Especially strong at the greenfield/prototype stage on small teams. Also happy tracking down stubborn bugs in complex systems.

I've worked remote for many years, both sync and async, with colleagues across many timezones.
