Summary
👤
Senior🎓
Top SchoolDavid W is a pragmatic, autodidactic software engineer with 12 years of experience building scalable APIs and infrastructure, currently driving payments engineering at Whatnot. He excels in Python, Elixir, TypeScript, and Rust, and has led systems-level work—from MySQL→Cassandra migrations and sharding to redesigning high-throughput tracking services—often authoring abstractions that simplify storage and query patterns. A declarative and functional-programming enthusiast with a domain-driven design mindset, he gravitates toward distributed systems, protocols, and CRDTs. Comfortable in Unixy toolchains and CLIs, he contributes open-source tooling and SDK fixes across ecosystems rather than focusing on a single flagship project. Outside engineering he’s a community-oriented volunteer who unwinds on the pickleball court and over strategy board games.
