Senior AI engineer at JANIE who built a voice AI receptionist that handled 10,000+ patient calls in its first three months.

Message

At JANIE, I built a real-time voice AI receptionist that handled 10,000+ patient calls in its first three months. It integrated with dental Practice Management Systems to automate appointment scheduling, patient lookup, and common patient requests.

I also built post-call analysis and patient search algorithms with OpenAI and Anthropic large language models. I developed observability and distributed tracing infrastructure, along with Model Context Protocol tools that gave AI coding agents access to debugging workflows.

Across fintech, telephony, and blockchain, I’ve built production systems with Go, TypeScript, and Python. At FAZE-1, I co-founded and bootstrapped a B2B SaaS company from concept to more than $1.1M in annual sales; at OPEN NETWORK SYSTEMS (ONS), I was Co-Founder / Co-CTO.
