What I'm looking for

I’m looking for a Data/Analytics role where I can build SQL + Power BI dashboards, automate reporting, and apply product metrics and A/B testing to deliver clear, data-driven decisions across teams.

I’m a Data Analyst who turns raw operational data into structured reports and dashboards that help teams make faster, better-informed decisions. I’m proficient in SQL (CTEs, window functions), Power BI, and Snowflake, and I’ve consistently replaced manual reporting processes with repeatable analytics.

In my recent work, I extracted and structured client asset and expenditure data from MySQL databases to support operational reporting. I built recurring Power BI and Excel reports to track spend dynamics and asset inventory, and I wrote SQL to extract, clean, and refine data for both scheduled and ad hoc reporting.

I also bring strong product-analytics fundamentals—monitoring product metrics (GGR, NGR, LTV, PRR, PAR), unit economics, and hypothesis testing using A/B testing. I’ve supported KPI monitoring through interactive dashboards and contributed to ETL planning with the Data Engineering team.

Earlier roles strengthened my analytical and cross-functional mindset: gathering and analyzing business data, defining requirements with stakeholders, and improving solution efficiency. I’ve worked with Python (pandas, numpy, matplotlib), built Power BI dashboards for insights, and performed SQL-based data quality and UAT testing to ensure reliable outcomes.
