Building products from idea to launch
I build and ship AI-powered apps and SaaS products from idea to launch. 4× first-place hackathon winner in the past year, most recently with Just Add at RevenueCat's Shipaton 2026. Currently building in public.
// about
I'm a product engineer with close to a decade of experience taking software from idea to App Store. These days I split my time between freelance work, helping teams design, build and ship their products end to end, and building apps of my own. If you need someone to own a product from first commit to launch, let's talk.
Hackathons are how I test ideas fast. In the past year I took first place four times: Storewave and Kraterion in the Walrus and Sui ecosystems, and Preplo and Just Add at RevenueCat's Shipyard and Shipaton. Right now I'm building Duskwatch, an iPhone app that tells on-call engineers what broke in their DigitalOcean infrastructure and whether it can wait.
Before going independent, I co-founded a Web3 studio where I led engineering on DeFi protocols and publishing tools, and ran 10+ developer education programs. I still give back to the developer community through hackathon mentoring and technical writing on Medium.

// stack
An AI-native toolkit — the tools I actually open every day to design, ship, and watch products in production.
// community
Beyond building products, I enjoy teaching and growing developer communities. I've organized and led 10+ developer education programs, helping hundreds of builders go from zero to their first shipped project.
I also participate in hackathons as both a builder and mentor, contribute to open-source, and create technical content. Helping developers level up is one of the most rewarding parts of this work.
