Rockstar🎓
Top SchoolZach Gollwitzer is a Senior Software Engineer with nine years of experience building high-performance full-stack systems and leading open-source projects from Cincinnati, Ohio. He led Maybe Finance’s rewrite to Ruby on Rails and maintained its 50k-star OSS repo, scaling the app to thousands of users while keeping P95 latency under 500ms through precomputed materializations, cache warming, and modular React components. Zach blends backend data engineering (event-sourced ledgers, CDC-driven ELT pipelines, Postgres/ClickHouse) with frontend polish (Next.js/React, Tailwind), and has experience shipping security- and compliance-sensitive systems (SEC registration, SOC 2). He’s comfortable across cloud ops (AWS/GCP, Docker, CI/CD) and modern ML/AI APIs, and his open-source contributions span both UI/UX fixes and robust testing of finance workflows. A former D1 student-athlete with a finance background, he brings quantitative rigor and competitive focus to product and performance problems.
