What I do
- Voice agent architecture and build: real-time agents with the backend, tools and MCP servers behind them.
- Conversation design that holds up: turn-taking, handoffs, latency and what the caller is told, treated as product decisions and not afterthoughts.
- Fractional CTO and technical advisory for teams moving from IVR and chatbots to voice agents.
- Developer, designer and product manager in one: I can take an idea from the first call flow to production.
