Summary
👤
Senior🎓
Top SchoolJohn Roach is a Lead Data and Machine Learning engineer based in New York with a Master's in Statistics and nearly a decade of experience building high-performance data pipelines, cloud ETL/ELT, and ML-driven analytics for finance and media. He has repeatedly optimized cost and performance at scale—most notably cutting Paramount’s core audience table footprint by ~90% and architecting low-latency streaming systems that processed tens of billions of transactions per day. Comfortable across the stack, he blends backend API and integration work (Plaid, Alpaca) with Spark/Databricks, Snowflake/Redshift, and production ML tooling in PyTorch/Keras. A former founder and CTO, he brings product-minded engineering to data problems and a knack for pragmatic security and governance improvements such as RSA-based credential hardening. Beyond ops and systems, he’s built bespoke web-scraping and async ingestion frameworks that power large-scale analyses, reflecting a rare mix of statistical rigor and hands-on systems design.
