Summary
👤
Senior🎓
Top SchoolSimon Korzun is an engineering manager with 15+ years of experience building teams and resilient systems that power consumer and marketplace products at scale. He has led platform and ML engineering teams that supported 200M+ MAU and delivered features tied to over $400M GMV, while driving measurable reliability and security gains (e.g., cutting account takeovers by 97% and reducing P1/P2 incidents ~35%). Simon combines hands-on architecture (feature-flagging infrastructure, REST/GraphQL APIs, and TypeScript/React front-ends) with operational rigor—introducing health-checking, embedding pipeline tests, and cost-saving infra optimizations. He’s shipped high-impact product work from interactive game maps that added 10M monthly pageviews to marketplace migrations that improved Core Web Vitals and deploy cadence. A founder-turned-manager, he validated and scaled an enterprise experimentation platform with microsecond p99 evaluation latency before sunsetting it based on go-to-market realities. Based in New York and raised in Vermont, he blends pragmatic engineering, product sensitivity, and a maker’s attention to craft.
