At Konfront, I build production ETL pipelines and cloud data platforms that integrate SAP, Odoo, REST APIs, Excel, and database tables, processing more than 1.5 million records daily. I reduced ETL runtime from eight hours to 1.5 hours through incremental processing and PySpark partition optimization.
I've designed five PostgreSQL and Databricks data warehouses using Bronze/Silver/Gold architecture, supporting financial, sales, retention, churn, predictive analytics, and roughly 25 analytical reports for AI/ML and business teams.
I also lead engineers across projects, automate Airflow workflows on AWS MWAA, manage EC2 infrastructure, and build FastAPI, AWS Lambda, and MCP services that connect APIs, databases, and AI tools.
