Summary

Rockstar🎓
Top SchoolJacob E is a Principal Engineer and Air Force veteran with nine years building reliable, developer-first platforms using TypeScript, React, Cloudflare Workers, and Go. He specializes in platform reliability, observability, and developer experience, having driven 99.9% uptime, cut critical errors by 72%, and taken test coverage from 0% to 100% for a 100K+ MAU e-commerce platform. At Cloudflare he helped ship Wrangler 2 and the Workers SDK, delivering dramatic local dev speedups (10x startup, 60x reload) and broader DX improvements that lowered deployment friction. A core OSS contributor (Create T3 App and Workers toolchain) and mentor active in Vets Who Code, he treats mentorship as community stewardship rather than a title. His background in military operations and wilderness skills shows up in disciplined runbooks, thorough migrations, and an obsession with predictable failure modes. Based in the PNW, he pairs hands-on engineering and tooling with a knack for turning observability into actionable truth.
