Experience

Stony Softworks

Founder & Product Engineer 2025 – Present

Founded and shipped Auxtra, a cross-platform music discovery app — built the full product end-to-end (feed algorithm, social graph, link resolution, invite system). Also built Dopplersky, a Bluesky analytics platform with 2,600+ users.

Rocket Alumni Solutions

Technical Product Manager 2025 – 2026

First product hire at a SaaS startup. Built the product function from zero — cadences, prioritization, cross-functional handoffs. Used customer interviews and usage data to build a retention thesis that redirected the company roadmap toward activation.

Can I Recycle This
