Mary is a Software Engineer at Afresh with 7 years of experience. She previously worked at Applied Predictive Technologies (APT), a Mastercard company, building cloud-based retail analytics software. At Afresh, she focuses on streamlining ETL pipelines, improving data processing through a patented retail entity resolution approach, and bringing new tools into the stack — including streaming, Lakebase, generative AI, and agentic workflows. An Ironman triathlete and endurance athlete outside of work, she brings the same slow-and-steady persistence to complex migrations and the same race-day readiness to shipping new technology.
