Summary
👤
Senior🎓
Top SchoolWilliam Freet is a pragmatic Software Engineer III with nine years of experience building payment systems, Golang microservices, and high-throughput backends from design through delivery. At Docker he led 3DSecure payment support and a Stripe migration that unlocked substantial new revenue, and previously built a Java-based payment processor at BillGO that cut costs by 60% while handling millions in daily transactions. He combines a strong backend stack (Go, Java, PostgreSQL) with practical engineering leadership—introducing end-to-end testing, feature-flagged rollouts, and performance-driven API and DB improvements that noticeably accelerate developer and support workflows. Comfortable in both startup and enterprise environments, he has shipped low-latency streaming features, SMS auth flows, and tooling that halves post-release defects. Outside work he channels strategic thinking into chess and disciplined practice at the piano, which hints at a methodical, iterative approach to problem solving.
