Product engineer in NJ. For nine years I helped build LBRY and Odysee, a Web3 YouTube alternative, growing it to 40M+ monthly visitors at its peak and seeing it through an acquisition in 2023. I take products from nothing to something people use, working closely with customers and execs along the way. The best part is watching people actually get value out of what I built. I do my best work with a mission I believe in and room to solve the problems I think matter.
One home screen for the apps you check all day: chats, email, calendar, feeds. A short digest up top, and an assistant that drafts the next step and waits for your OK. Every user gets their own confidential VM that runs their secure chat bridges and a browser, and LLM calls are end-to-end encrypted. Idea to working product in three months.
Tell it what you need and it makes the phone call for you, in a clone of your voice if you like. You follow along on a live transcript, and the personal details it needs are encrypted and saved across calls, so you only give them once.
The open-source part. A Zcash wallet engine in Rust, compiled to WebAssembly, with a TypeScript SDK. Alpha.
A private Zcash wallet regular people can use, on desktop, mobile and web. It syncs through its own private gateway, so the server can’t tell who you are or which transactions you’re looking up. Next to it, z-stack, my open-source wallet engine.
Odysee, 2021–2026. Co-founder, COO and CTO. Peaked at 40M+ monthly visitors and was acquired in 2023. I ran the company with the exec team and still shipped: the Roku app, going live from the browser, a rebuilt odysee.com, and 300+ merged pull requests.
LBRY, 2017–2021. Worked with engineering on the desktop app and lbry.tv, testing releases and shipping fixes (300+ merged pull requests), while they grew from hundreds of daily users to millions.
U.S. Army, 2010–2017. Reporting systems for ten-plus ammunition programs. Developer to team lead.
FabSoft, 2009–2010. A workflow designer clients could use themselves.
Starting something? I’d like to hear about it.
