Data Engineer and Database Developer focused on scalable data warehouses and high-performance ETL/ELT pipelines.

What I'm looking for

I’m looking to build scalable data warehouses and high-performance analytics—designing modern data models, reliable ETL/ELT pipelines, and optimizing queries so teams can make data-driven decisions.

I’m a Database Developer and Data Engineer with a distinct path from banking into technology. My earlier leadership experience as a Branch Manager sharpened my stakeholder management, problem-solving, and ability to turn business needs into practical technical solutions.

Today, I specialize in designing, implementing, and optimizing enterprise Data Warehouses. I’m deeply focused on modern data modeling—especially Data Vault 2.0 (Hubs, Links, Satellites, PIT/Bridge tables)—and also use dimensional modeling (Star/Snowflake schemas), normalization, and schema optimization.

In my current work, I design and optimize complex database structures and queries for high-performance analytics, and I build and maintain robust ETL/ELT pipelines using Apache Airflow and Loginom. I enjoy troubleshooting bottlenecks to keep both classical and Data Vault DWH architectures stable, while keeping data integration and quality validation dependable.
