About Me

Electronics Engineer turned Data Engineer — bridging hardware logic with cloud-scale data architecture.

My path started in electronics and project site engineering, where I developed a rigorous systems-thinking mindset. Today, I design and build robust ETL pipelines, cloud data platforms, and analytics infrastructure that scale from prototype to production.

I specialize in the modern data stack — orchestrating complex workflows on AWS, transforming data at scale with Databricks and Spark, and building warehousing solutions on Snowflake. I believe good data engineering is invisible: it just works, every time.
