Summary
Zac Barnes is a Staff Software Engineer with 11 years of experience building scalable, production-grade systems across startups and large enterprises like Vinli, Toyota Connected, PepsiCo, and Ramp. He’s a pragmatic full-stack developer who moved from mortgage underwriting into software after an intensive Dev Bootcamp, and he excels at turning greenfield projects into reliable services and APIs. Zac has hands-on experience with microservice architectures that handled tens of billions of data points and 100M+ daily API calls, and he’s led hiring and team formation efforts including establishing a European engineering presence in London. Known as a craftsman who values elegant, useful code, he combines technical rigor with mentorship—onboarding and training new engineers while driving measurable business impact. Unusually for a senior engineer, his career began in mortgage operations, which contributes to his disciplined, metrics-driven approach to delivery.
