I'm currently building PostgreSQL data models, GraphQL APIs, and Angular dashboards at PerfAnalysis Consulting, enabling cross-filtering, standings, and detailed multi-dimensional performance analysis.

I've applied machine learning and data engineering across Philip Morris International, Vermeg Solutions, E.P.S.M.C Data Analytics, and Wevioo. My work includes analyzing 602M battery-performance observations, forecasting transaction and sales trends, automating trade-data extraction, and delivering Power BI dashboards that support product, financial, and HR decisions.
