What I'm looking for

I'm looking to build and scale meaningful full-stack SaaS and AI products, owning work from product design through production while mentoring engineers and solving complex, data-heavy problems.

I've built production SaaS, APIs, and data-heavy platforms for 15+ years, from Breezy's founding build to Carvana systems handling 1.5M+ requests per hour. At Breezy, I built core financial modules that supported growth from $0 to $250K+ ARR, alongside payments, lending, QuickBooks integrations, mobile workflows, and AI recommendations.

At BrightHire, I ship privacy-sensitive AI hiring products including the Slack Hiring Agent and Voice AI Interviewer capabilities supporting 3,000+ AI interviews per month. I work across TypeScript, React, Node, data modeling, retrieval workflows, and AI evaluation, while mentoring engineers and setting the quality bar for production releases.
