Summary
Applied AI engineer building voice agents that answer real phone calls and retrieval systems that cite their sources. Most recently at AutoAce (YC F25) on the voice-agent OS for car dealerships - cut voice-loop latency 8.5s → 3.9s, backfilled dropped calls, and shipped a three-layer LiveKit fence in production.
Experience
Applied AI Engineer - AutoAce (YC F25)
Jun 2026 - Jul 2026 · Boston, MA
- Built the voice-agent OS for car dealerships: telephony integration carrying live inbound calls end to end.
- Cut voice-loop latency 8.5s → 3.9s by parallelizing call startup, deduplicating graph fetches, and moving blocking TTS init off the async event loop.
- Backfilled 13 dropped calls into recoverable sessions and shipped a three-layer LiveKit fence so concurrent calls fail over instead of dying mid-conversation.
