Full-stack software engineer. I design, build, test, and ship software end to end.
- Currently at VantaSoft, doing hands-on engineering across Amira Learning (enterprise EdTech), Telvana (AI voice agents), and CardSync (trading-card commerce).
- Previously at Blink Labs building Cardano products, wallet and rewards flows, and edge infrastructure.
- Co-created Zusty, a Zustand DevTools extension with 128 stars and an official ecosystem listing.
- I use Claude and Codex agent workflows for repetitive work and test coverage, and I make the final call on what ships.
This is my work account. Open-source and side projects live on @JaeBrian.
