I build things. Some have worked better than others. I don’t dance.
Currently
building.
Five projects. A podcast that listens to your portfolio. A desktop app defending your inbox. A menu bar app for Slack-style emoji shortcuts. A platform powering white-labeled travel rewards. A non-profit teaching kids to save lives.
StockCar · a podcast of your portfolio
AI-generated audio briefings on your stocks, crypto, indices, and forex. Pre-market to after-hours, ready in under 10 seconds. Free on iOS, no account needed.
Premail · your inbox, defended
Privacy-first email filtering for Mac, Windows, and Linux. Silently removes spam, recruiters, and noise before you ever see it. No account, no servers touching your email.
Comoji · :emoji: autocomplete, everywhere
A tiny macOS menu bar app that brings Slack-style colon emoji shortcuts to every text field you already use. Type :liz, press Tab, get a lizard. Privacy-first and runs entirely on your Mac.
Bee Ready · lifesaving skills, one game at a time
Teaching young athletes CPR, AED awareness, and emergency confidence, built directly into youth sports. Prepared kids. Stronger sidelines.
BookIt · rewards, travel, retail at scale
White-labeled rewards powered by the best in travel, retail, and VIP experiences. 20M+ tickets, 2M+ stays, 2,000+ premium brands. My day job.
A long line
of attempts.
Some shipped to acquisition, some taught me what not to do next time. Both counted.
Feb 2018 → Oct 2023LolliDunnoEarn bitcoin when you shop online, partnered with 1,000+ top merchants. Built engineering from zero through Series A.Co-founder · CTO
The consumer side of Lolli was sold to Thesis, and the backend guts were renamed to some other company name that I can never remember.
That happened after I left, so I do not really keep up with it.
Does not really count as an acquisition, I do not think.

Always happy to talk shop with people who are shipping things.
