Diarken Nurtayev

I'm a Data Engineer with 4+ years of experience, based in Astana, Kazakhstan, looking for remote opportunities with teams in Europe or the US. Most of my serious work happened at Teleperformance, where I built and maintained data pipelines for Trust & Safety on a major global streaming platform. Over 2 years I processed 40,000+ moderation cases without dropping below a 100% quality score. I also led the migration of our processing stack from Pandas to Polars to PySpark — which cut memory usage by 60% and made our pipelines roughly 3x faster. Airflow handled orchestration throughout. Before that, logistics data at KzCargo, and currently data engineering and reporting automation at a construction company in Kazakhstan. My stack: Python, PySpark, SQL, PostgreSQL, Airflow, Docker. I'm actively working with AWS and dbt right now. I care a lot about data quality — not just getting data somewhere, but getting it there correctly and reliably. I tend to automate anything that gets done more than twice. Fluent in English. Available immediately.
