Today, I'm refactoring healthcare as co-founder and CTO of Flexpa. We can link identified claims data from anyone.

Previously, I was a solo-founder in Y Combinator's Winter 2020 batch. Before that I was CTO @ Universe, acquired by Live Nation in 2015 where I managed a product team of 30.

I also advise a small number of ambitious companies.

TypeScript is my greenfield language of choice. Ruby (Rails) was the first language I loved. Elixir and Rust are my weekend project languages. When necessary, I can build in Python and Go too.

On the frontend, I usually work with React, Next.js, and TailwindCSS. My preferred design tool is Figma.

As far as protocols and query languages go, I launched a GraphQL API at Universe in 2017 (way before it became mainstream - no I wouldn't do it again). I have special depth with OAuth - having launched Ticketmaster's production fan OAuth service.

I'm unreasonably effective at data modelling. PostgreSQL and SQLite (totally underrated) are my go-tos database-wise.

Recently, my work in healthcare has led to special knowledge of protocols like FHIR.

Before anyone had heard about dog-themed meme coins and bored apes, I was building on Ethereum, Solidity, and web3.js at ETHGlobal (Waterloo, Denver, and San Francisco).

• Bitcoin Core contributor, my first commits appeared in the release notes for 25.0, and I am the maintainer of finney - a TypeScript toolkit for Bitcoin.
• Featured alongside Naveen Selvadurai (founder, Foursquare), The Verge wrote about my quantified-self tracking application
• Four years ago, before you had heard of NFTs, I won OpenZepplin's ETHDenver bounty extending their industry ERC721 contract to create DecentPost - the first decentralized logistics app
