What I'm looking for

I’m looking for a data engineering role where I can build reliable ETL/ELT pipelines, optimize SQL performance, and turn data into clear reports that help both technical and business teams move faster.

I build automated ETL/ELT pipelines that help teams resolve real operational issues faster. At Traxion Tech, I used Python and SQL to create an ETL/ELT workflow that enabled an 11-person operations team to catch up on unposted transactions, and I cut query execution time by 66% (from 15 minutes down to 5 minutes) by finding bottlenecks and rewriting complex SQL.

I also manage large-scale databases and translate data into decisions. I’ve supported MS SQL Server databases holding billions of records through daily health checks, backup monitoring, and investigation of data anomalies, and I supported operations and developers by extracting data and building custom SSRS reports. Earlier, as a Database Management Intern at DES Financing Corporation, I transformed raw data into actionable insights using Excel visualizations and reports—work I’m continuing to grow through hands-on projects using Python, pandas, Docker/Docker Compose, and PostgreSQL.

Bridging the gap between raw data and business teams as a Junior Database Engineer. It involves handling ad hoc requests and building ETL pipelines to route data smoothly. System health stays optimal through routine maintenance and tuning SQL queries for speed. When data issues pop up, querying and investigations ensure all reporting stays perfectly accurate
