Senior🎓
Top SchoolShaun Wang is a Senior Software Engineer with a decade of experience building large-scale full-stack and backend systems, now based in Phoenix. He has driven production features across consumer and logistics platforms at Instacart and Gopuff, and previously owned a high-revenue B2B e-commerce platform and delivery innovations that directly improved customer retention. Shaun is an active open-source contributor to the Substrate/Polkadot ecosystem—working on Polkadot, Cumulus, Acala and core Substrate components—specializing in XCM messaging, parachain interactions, runtime logic, and low-level storage semantics. His background blends pragmatic product delivery (event tracking, notification systems, same-day delivery flows) with deep protocol-level engineering, enabling him to move fluidly between business-facing features and blockchain runtime internals. Known for meticulous, detail-oriented code and cross-domain ownership, he often surfaces subtle fixes (e.g., encoding, trait derivations, and storage mutation helpers) that improve stability at scale.
