What I'm looking for

I'm looking for remote data, AI quality, or analytics work where I can validate complex datasets, investigate anomalies, build reliable reporting, and support evidence-based decisions.

I've audited e-commerce, industrial, and commercial datasets to uncover methodology errors, validate results, and turn complex records into reliable decisions. In one distribution audit, I proved reported 26% growth was actually 6.1%.

At Academica, I processed and reconciled 100,000+ e-commerce rows, identified two customer segments driving 60% of revenue, and built SQL datasets and Power BI/Tableau dashboards for performance analysis.

At Kyzylorda Combined Heat and Power Plant, I analyze machinery time series, flag pre-failure anomalies, and maintain evidence-based technical logs. My work combines SQL, Python, Excel, statistics, data privacy, and rigorous quality validation.
