(02) — About my work

What I do

I build services in Go and Java and work with Python and SQL for analysis. Alongside my own projects, I contribute fixes and reproducible bug reports to open source: a merged calendar fix for VetLog and a terminal-behavior investigation for OpenAI Codex.

Before this I was a Product Delivery Associate at athenahealth, building Power BI reporting on Salesforce case data, investigating data issues with Snowflake SQL, and writing a small Python tool that replaced a manual Excel verification step.

Software engineering. Services, APIs and integration boundaries in Go and Java.
Data analysis. Cleaning, definitions and validation in Python and SQL.
Workflow integration. Connecting systems, with a person reviewing the risky step.
