What I'm looking for

I’m seeking roles where I can build cloud-native data pipelines, apply Python and analytics skills, collaborate across global teams, and grow in data engineering and business analytics.

I’m a results-driven and adaptable data engineer with extensive experience designing and automating ETL/ELT pipelines for global reporting in banking, healthcare, and enterprise environments.

I’ve led migrations from on-premise to cloud-native architectures, rebuilt automation logic, and optimized complex SQL and PL/SQL systems to improve performance and reliability. My work has been recognized as a benchmark within organizations for quality and impact.

I communicate clearly with technical and non-technical stakeholders, foster positive team dynamics, and continually expand my skills in Python, dbt, Airflow, and cloud technologies to deliver practical, value-adding solutions.
