At Smartech (A Hexion Company), I designed ingestion pipelines that move MongoDB data into an Apache Iceberg lakehouse and deliver query-ready datasets across the organization.
I build distributed ETL/ELT pipelines with Python, SQL, and Apache Spark, and use Trino and DuckDB for analytical queries. I also orchestrate production workflows in Prefect, including cleaning, transformation, scheduling, retries, and monitoring.
At Final, I prepared large-scale datasets for machine learning and automated dataset collection and management with Python, Bash, and C# scripts. I also designed data models and built React dashboards for financial data.
At Bar Ilan University, I developed a Node.js web application serving thousands of concurrent users and optimized MongoDB data access with Mongoose and Redis caching.
