I'm Oca, a Jr. System Analyst Engineer for T-Mobile, Ultra Mobile and Mint Mobile, based in Brooklyn, NY, and growing into Data Engineering.
Outside of work I build end-to-end products: a serverless ETL on AWS and Snowflake, a market-data platform that refreshes itself every day, and a full-stack ride app for New York.
My path started in IT support and operations leadership. Today I bring that operational discipline to data pipelines, system analysis and software.
