Hey, I'm Zeta 👋
Founder & Software Engineer · 15 years in
I build products from nothing and ship them.
01 / About
Right now I'm building real-time voice AI agents: SIP telephony, multilingual speech, turn-taking, and the evals and metrics that keep them honest in production.
I've co-founded companies, consumer and B2B, and led small teams. What I actually like is owning the whole product, not a slice of it.
I work best as a founding engineer or an early senior hire.
Small team, high autonomy, ship over process.
