[01]Manifesto
I'm a full-stack developer with a decade of hands-on production work — including aerospace (Blue Origin) and financial services (Zions, Discover). Not pitches, not roadmaps — the actual thing, in front of users, surviving Monday morning.
React, Redux, TypeScript, Node.js, REST + GraphQL, Postgres, AWS. I write code that's easy to delete and hard to break. Available for contract or full-time — hands on the keyboard, shipping features that work.

[02]Capabilities
What I'm good at (honestly).
Four lanes. Across the stack, end to end. No hand-offs.

Back of house
Node.js + Express middle-tier APIs (REST and GraphQL) integrating with Postgres, Mongo, Oracle, Cassandra. Schema design, query performance, the boring parts that keep things up.
