What I'm looking for

I am looking for a role building scalable, production-grade data pipelines with opportunities to automate workflows, improve observability, and collaborate cross-functionally in a growth-oriented team.

I am a data engineer with hands-on experience designing, developing, and maintaining scalable ETL/ELT pipelines using Python, Apache Airflow, and Spark to process large datasets efficiently.

I have implemented containerized data applications with Docker, built monitoring dashboards in Grafana, and written complex SQL queries across Hive, Oracle, PostgreSQL, and other systems to ensure reliable data delivery.

I previously migrated databases, automated billing and data processes using PL/SQL and Python, and worked closely with cross-functional teams including Development, Infrastructure, Quality Control, and Operations to deliver robust data and configuration services.

I hold advanced technical training in information security and IT systems engineering, and I seek to bring data-driven engineering, automation, and observability best practices to production-scale data platforms.
