👋 Hey there!

I'm Zeta. Software engineer and founder, 15 years in.

Currently building voice agents on LiveKit. SIP telephony, provider-agnostic STT/TTS, streaming LLM with TTFT tracking, and evals for turn-taking across 10+ languages.

Also Coffee Master, my specialty coffee app, shipping to iOS and Android.

I've cofounded multiple companies and shipped products in consumer, B2B SaaS, and developer tools. Hired and led small engineering teams. One company went through Lanzadera. Didn't make it.

Daily stack: TypeScript, Next.js, React Native (Expo), Supabase. Deep Rails background.

Across the stack I've shipped LLM eval pipelines, embedded firmware, billing systems, and App Store releases.

I work best as a founding engineer or early senior hire. The kind of seat where you don't know what you're building yet and the stack changes with the problem. Shipping matters more than process.

I've worked on distributed async teams for years. I'd rather not go back.
