Summary
👤
Senior🎓
Top SchoolDenis Khvorostin is an experienced ETL developer and data engineer with over a decade building pipelines, warehouses and analytics solutions across finance, media and cultural institutions. He blends deep SQL and Python skills (PostgreSQL/Greenplum, MariaDB) with pragmatic PHP/DBA experience for maintaining and modernizing legacy systems and high-volume data flows. A former university lecturer and linguist (PhD-level background) he brings a researcher's rigor to data cleaning, taxonomy design and domain-driven development, evidenced by long-term projects like a technological grant–backed study of modern Russian adjectives. Comfortable moving from raw PDFs and scanned binaries into structured warehouses to supporting risk-assessment analytics, he’s as adept at writing ETL as at negotiating business requirements into formalized data models.
