Yaroslav Z.

I help software companies build effective engineering teams, make sound architectural decisions, and deliver business-critical products reliably. I bring 20+ years of software engineering experience and 10+ years leading distributed, cross-functional teams. I combine engineering management and technical leadership with hands-on development experience: building web applications with Angular and backend services with NestJS, using TypeScript across the stack. At Upwork, I led a distributed 10-person engineering team across backend, frontend, and QA, responsible for high-scale payout and reporting systems on a platform with $3B+ in annual transaction volume. I owned engineering delivery, reliability, and availability, and worked closely with product managers and designers on priorities and execution. I have 20,000+ hours on Upwork with consistent 5-star feedback across long-term engagements, including extensive work on Upwork's own platform since the oDesk era.
