I helped build Twitter and scaled the company from 50 servers to 250,000+ servers.
I've launched three startups in my career and currently run one from my home office.
Most recently I designed, got funding for, and built a wearable wireless-networked videogame/badge for Defcon 25 (https://dc25spqr.com). I raised over $30,000 on kickstarter and direct sponsorships. I designed the PCB and Schematic for that device -- I do hardware too!
