Message

At Digitain, I validate data warehouse tables and BI reports, tracing discrepancies back to their source. I built repeatable Python checks for BI reports and set up an OpenAI Codex workspace to automate daily QA workflows.

At StockAgents, I built Python ETL pipelines for financial data and developed machine learning models to predict stock moves on earnings-announcement day. Earlier, I supported semiconductor customers at National Instruments with LabVIEW and TestStand applications, and developed features for a logistics platform as an intern at Less Platform.
