What I'm looking for

I'm looking to build and scale practical products where I can own architecture, ship MVPs, solve production problems at root cause, and connect engineering decisions to product growth and business outcomes.

At Air Radar LLC, I owned technical strategy, architecture, and engineering operations for AirRadar Pro, a real-time market intelligence platform spanning APIs, data pipelines, and AI-powered insights.

I migrated production from AWS Amplify to a self-hosted Docker deployment behind Cloudflare, cutting monthly infrastructure spend to near zero. I also resolved DDoS, email deliverability, and security incidents at root cause while improving caching and Core Web Vitals across high-traffic surfaces.

I've built and led lean distributed teams, hiring a Tech Lead, designers, writers, and video producers without outside funding. Alongside my CTO work, I built an MVP for Oyen Homes, an AI-powered real estate search platform serving major US markets.

My engineering work is informed by eight years in digital marketing and growth, including paid acquisition, technical SEO, analytics, funnels, and campaigns generating six-figure monthly B2B revenue and more than $500,000 in event revenue.
