Data Scientist driving product analytics, experiments, and ML insights.
ArmeniaWhat I'm looking for
I’m a Data Scientist focused on product analytics, A/B testing, statistical modeling, and machine learning. I translate user and product data into actionable decisions that teams can trust and move on.
I’ve designed and evaluated experiments using Welch t-tests, chi-square tests, and randomization balance checks. I also analyze funnels and user engagement across web and mobile, using statistical rigor to measure engagement, conversion, and variant impact.
On the engineering side, I build reproducible analytics pipelines in Databricks with PySpark, SQL, Delta Lake, Parquet, and AWS S3. I deliver results through Looker dashboards, so insights are easy to understand and operationalize.
Before data science, I worked as a programmer—building and maintaining SQL Server databases and developing desktop and web applications. That background helps me collaborate well across teams, define requirements clearly, and ship analytics that are both accurate and maintainable.
