What I'm looking for

I seek roles where I can design and maintain scalable cloud data platforms, build reliable ETL pipelines, collaborate with analytics teams, and continue growing my data engineering expertise.

I am a Data Engineer who began as a developer and found my niche designing, building, and maintaining data lakes and data warehouses on cloud platforms. I transform raw data into reliable, actionable assets using tools like Snowflake, Databricks, BigQuery, Python, and modern ETL frameworks, and I take pride in ensuring data quality and accessibility for business decisions.

My experience spans insurance, mobility, education, and public sector projects, where I built robust pipelines, read replicas, and integrated multiple data sources for analytics. I continuously seek to deepen my technical craft while delivering scalable solutions that enable teams to analyze millions of events and drive insight-driven outcomes.
