🎙️🤖 Real-time Voice systems powering AI agents at Ada.

On the Voice team at Ada, I'm helping build the platform powering Ada's automated customer experience (ACX) transformation. Delivering a Voice experience with ever-improving latency — streaming speech-to-text and text-to-speech, handling interruptions, noise filtering, and more.


🛠️ What I work on

  • Real-time latency — voice is unforgiving; the first few seconds decide whether a call feels responsive or broken. Much of the work is measuring and shaving the round trip from caller to response.
  • Distributed systems — keeping call state coherent across a cluster, with reliable routing and graceful fallbacks.
  • The voice experience — streaming STT/TTS, interruption handling, noise filtering, and call transfers, all under a real-time clock.

Before Ada, I built distributed sports-betting systems in Elixir/Phoenix at theScore Bet, built out the autos vertical at Kijiji, and worked on the first iteration of the Ericsson Network Manager — the last two in Java.
