Founder & Lead Developer at Oxigenic

I'm an iOS developer and founder based in New York with over a decade of experience building apps for the consumer market. I started Oxigenic to do what I love full-time — designing, developing, and shipping products that are genuinely useful and polished enough to stand out.

I've worked across the full stack — from native Swift and SwiftUI to backend infrastructure and REST APIs — in industries ranging from healthcare to public safety. Whether I'm taking on a client project or building my own apps, I care about the details: performance, design, and user experience.
