About

I'm a senior Rails engineer with nine years of full-stack experience modernizing complex legacy systems and shipping payments infrastructure at scale. At PayPal/Braintree I worked on the FX Optimizer and Pay with Venmo. At Apple I streamlined internal Marcom tools used across the company. I'm an early adopter of agentic AI engineering — using Claude Code and GitHub Copilot to run autonomous multi-step development workflows in production. Looking for a senior IC role at a company that takes AI-assisted engineering seriously.
