About Me

Software engineer working across frontend, backend, and data infrastructure. Day-to-day I build BI platforms and e-commerce data systems using React, Go, Python, and dbt on Snowflake / BigQuery / Redshift.

I typically work on multiple client projects at the same time, sometimes solo, sometimes as part of a team.

Open to remote work and international collaboration.
