Thomas Zarebczan New Jersey Open to opportunities currently building a few things

I’m a seasoned generalist.
I build software.
And run the companies.

Co-founder, COO & acting CTO at Odysee, 2021–2026. Sixteen years across engineering, product, and operations before that.


About

I’m a generalist. For about sixteen years I’ve worked across engineering, product, operations, and direct client and user support, mostly at small companies where those roles overlap. Doing all of it, and talking to users directly, is what taught me how and what to build, with real taste and care for UX.

Most recently I co-founded Odysee, a video platform, and ran it as COO while acting as CTO. We grew to tens of millions of users. The job covered strategy, hiring, leading all the technical teams, and vendor integrations + management, plus a fair amount of product, design, engineering, and code.

Before that I spent seven years building SAP business-intelligence systems for the U.S. Army. Not glamorous, but it taught me how to finish what I start.

Lately I mostly build on my own: a Zcash wallet, a cross-platform disk and monitoring tool, and various experiments with AI agents and crypto. I’m also building something in stealth: a social aggregator that ties together chat, community, AI, and content.

Co-founder, COO & acting CTO

Odysee · formerly LBRY

Co-founded the company and ran it day to day as COO while also acting as CTO. I set technical direction, managed the team and our vendors, helped hire, and kept writing code.

  • Rebuilt much of the odysee.com stack and made it noticeably faster.
  • Built and shipped the Odysee Roku app, and moved livestreaming to broadcasting from the browser.
  • Kept the YouTube importer alive; it broke whenever YouTube changed something.
  • Migrated the payments wallet to Arweave without disrupting users.

Product, engineering & operations lead

Odysee · after the LBRY split

Took over operations when LBRY split into Odysee. I ran the support and product teams and set roadmaps across the web app, mobile, Roku, and accounts, while traffic peaked around 35 million monthly users.

  • Headed operations and finances for the new company.
  • Set product direction across five-plus projects at once.
  • Filled in as technical lead when we needed one.

Support, community & project management

LBRY

Ran support and community for LBRY across every channel we had, through the stretch where it went from a few hundred daily users to millions. Tested features, filed bugs, and wrote the monthly development updates.

  • Handled support across the helpdesk, Twitter, Discord, Slack, and Reddit.
  • Worked closely with engineering to turn user reports into fixes.
  • Contributed to the front end and back end.

Off the clock.

Proud husband and father to two girls.

I drink too much pour-over coffee. I built an app for it.

I read and stay on top of all things tech, AI, and crypto.


A few things about me.

off the résumé
01
The SEC

I was interviewed by the SEC for a full day during the LBRY case. Lawyers prepped me beforehand. Stressful, but eye-opening.

02
The hack

In 2014, bad security habits got my crypto wallet hacked. I went down the rabbit hole and tracked the guy down myself. It was a few thousand dollars then; it would be millions today. I let it go, but learned a ton in the process.

03
The 51% attack

At LBRY I once fought off someone 51%-attacking the chain, renting hash power to make the attack cost more until it stopped being worth it for him.

04
Lawn care

I take my lawn far too seriously. Weed-free and properly nourished, always.

05
The bear

My first-ever backpacking trip ended with a bear taking over our lean-to, eating all my food, and drinking my rum.
