Work Experience
Nov 2023 - Present
Newcast · Remote
Co-Founder
Building the next generation of real-time voice agents — where AI reasoning meets human-like interaction.
- Co-founded Newcast and led the technical direction, driving architecture design, rapid prototyping, and early product validation for real-time AI voice agents.
- Built the initial MVP integrating LLM reasoning, speech streaming, and contextual memory, enabling natural, low-latency dialogue between users and agents.
- Designed and implemented modular RAG and function-calling backends (LangChain + FastAPI + Pinecone) supporting dynamic API, database, and tool access.
- Architected and deployed containerized microservices on AWS ECS with CI/CD automation, observability, and auto-scaling for multi-environment reliability.
- Collaborated closely with product and GTM co-founders to align technical capabilities with market feedback and evolving user experience goals.
