Full-stack engineer — TypeScript, AWS, AI-assisted development
Summary
I'm a full-stack engineer with seven years building high-throughput distributed systems and cloud infrastructure — from email delivery at a 99.99% SLA to enterprise pricing and payments. I work daily with AI-assisted development (Cursor, Claude Code, MCP), lean toward the backend, and like living at the seam between engineering and product.
Highlights
- Built and operated Node.js services delivering 3.3B+ emails/day at peaks of 250M/hour on a 99.99% SLA at SparkPost.
- Shipped an end-to-end data pipeline and a production payments experience (Zuora + Stripe) at Pie Insurance.
- Owned customer-facing features across React + Django on a complex SQL data model at Quorum, used by Walmart, Google, and the US Air Force.
- Daily AI-assisted developer — authored custom workflows and drove AI-tooling adoption across the team.
