What I'm looking for

I'm looking to build reliable, scalable full-stack products in workflow-heavy domains, where I can own architecture, improve production quality, mentor engineers, and partner with product, design, and DevOps.

At Cast & Crew, I build production payroll workflow features with TypeScript, React, Node.js, REST APIs, and PostgreSQL, improving workflow defect rates by 18% and median response time by 22%.

I've also delivered healthcare order orchestration at Parachute Health, cross-border checkout capabilities at Global-e, and internal commerce tools at Nike. Across these workflow-heavy products, I strengthen testing, CI/CD, observability, SQL performance, and maintainable service architecture while mentoring engineers and partnering closely with product, design, and DevOps.
