What I'm looking for

I’m looking for a data engineering role where I can build reliable ETL pipelines and analytics platforms, strengthen data quality and governance, and deliver clear dashboards using Python, SQL, and cloud services.

I’m a Data Engineer with 6+ years of experience building scalable data pipelines and analytics platforms across consulting, BPO, and public sector environments. I design end-to-end data architectures and ETL pipelines—covering ingestion, transformation, deployment, and reporting workflows—while partnering with stakeholders to replace manual processes with automated dashboards and centralized pipelines.

In my current role as a Data Engineering Consultant, I improve reporting performance by optimizing SQL queries and database schemas and I onboard teams to new data models and reporting systems. Previously, I built and maintained high-volume ETL pipelines, mentored analysts on SQL and data quality validation, and increased data reliability and reporting speed by ~30% through governance standards and validation frameworks.
