Rockstar🎓
Top SchoolJames Sheehan is a senior frontend engineer based in Austin with eight years of experience building production-grade React and TypeScript systems for high-traffic e-commerce, Web3 protocols, and hardware-plus-wellness startups. He’s shipped zero-to-one frontends for multiple blockchains (Solana, Aptos, Movement) and designed TypeScript SDKs and cross-chain tooling that translate complex token and reserve models into usable interfaces. As a founding engineer he owned end-to-end frontend, analytics, CRM and growth systems—building multi-stage funnels, offline attribution, and tiered affiliate programs that tied behavior to revenue. Comfortable across full-stack product development, he brings a strong focus on performance, observability, and audit-ready CI/TDD practices. Notably, he combines hands-on UI architecture with analytics-driven growth engineering, making product decisions backed by session replay and lifecycle reporting.
