About Me

I'm a Senior Analytics Engineer at Optum with nearly 4 years of experience designing and building production data systems. I specialize in creating modular, scalable pipelines and self-service frameworks that empower analyst teams.

My work spans framework development for API-to-warehouse ingestion, orchestration with Airflow and dbt, and deploying dashboards that serve 100+ monthly users. I also build and publish open-source tools — including a PyPI package for Adobe Analytics — and contribute to projects like Preswald.

Outside of work, I've completed 100+ freelance Python projects on Fiverr, ranging from web scraping bots to full web applications.
