About

I’m Paul — an engineering leader and hands-on architect based in Boulder, CO, with 18+ years building secure mobile, backend, and crypto systems.

Today I’m Director of Engineering at Casa, leading a 12-person team and driving AI-first development workflows across engineering and product. Before that I spent six years there as a Staff Engineer, architecting Android key-management systems and on-chain Ethereum multi-signature designs for Casa’s non-custodial Bitcoin and Ethereum security products. Earlier I spent seven years at Mobiquity as a Principal Android Developer, including leading the team behind the first mobile app approved by the FDA as a medical device.

These days I mostly work in Kotlin, TypeScript, and Solidity on top of AWS, and write here about blockchain engineering, applied cryptography, and AI-assisted development.
