A record of my work, experiments, and interests.

Projects & Work Experience
Work Experience
TBA - Event ticketing platform for creators.
Engineering Lead & Full Stack Developer
I led the rebuild of TBA into a scalable event platform with analytics and community features. In a year, it powered $1.39M in ticket sales and brought in more than 4,000 new users.
We added tools for creators create events, price their tickets, and manage their events to boost community engagement.

Personal Projects
Tribe Social
Product Manager
Tribe is a social platform I built for like-minded people to form small, public groups around shared goals.
I designed and engineered everything end-to-end using Next.js, Postgres, and the AT Protocol with a custom PDS connected via Firehose. The platform lets tribe owners post, while members from other tribes can reply, like, and build trust in open yet focused communities.If you are an engineer reading this, join the Engineers on Break tribe or explore and create your own at tribesocial.me
