Oleg Vaskevich is an engineering manager and former tech lead with 13 years of experience building scalable product platforms and AI-driven knowledge systems, currently leading Cross-Product Services at Superhuman to unify Coda, Grammarly, Mail, and Go into a single bundled experience. He joined Coda in stealth and spent nearly nine years scaling its infrastructure, monetization (Stripe-powered billing), Packs ecosystem, and the internal RAG system "Coda Brain" that now underpins Superhuman Go. Early internships at Twitter, Google, and Shape Security, plus a KPCB fellowship, shaped his background in security, SRE, and platform engineering—he’s been shipping code since age 12. A pragmatic leader who blends high-scale technical rigor with user-focused product thinking, he also contributes to open-source TypeScript type definitions in DefinitelyTyped.
