Engagements

02/2026 — 10/2026

Senior AI Engineer & Technical AdvisorDialpad

Developed a modular Python voice/text agent-runtime prototype with LiveKit and SIP/WebRTC, including speech recognition, LLM and speech synthesis integration, transfers, keypad input and interruption handling. Built evaluations for latency, behavior, task completion and model cost. Developed the MCP Agent Builder for agent authoring, integrations and adoption, with OAuth, tenant-scoped access and text/voice tests; deployed and tested it as an internal staging beta. Advised Telephony Engineering and helped engineers adopt QualityLayer, Claude Code and Codex through workshops, labs and pair programming.
