L1 Identity
Whoami
Senior engineer with 15+ years building and running high-load, real-time platforms. Most recently I built a production voice AI support agent: real-time audio, voice activity detection, speech-to-text and text-to-speech, and agentic call flows.
Full-stack in TypeScript, Node.js, React and Next.js, with Go and Python. Strong on AWS and GCP, infrastructure as code and CI/CD. I led JavaScript engineering teams for six years and owned 24/7 production uptime.
