My core specialty is conversational AI over the phone: AI receptionists, appointment setters, outbound agents, and call automation built with ElevenLabs, Whisper, Twilio, LiveKit, Agora, and modern LLM stacks (OpenAI, Claude). I’ve delivered systems that answer every call, book directly into calendars, send transcripts in near-real time, and gracefully escalate to humans when needed. For structured, compliance-sensitive use cases, I also implement Dialogflow CX as a deterministic conversation layer—paired with LLMs where flexibility is required. This hybrid approach gives clients both reliability and natural speech. Beyond voice, I consult on: OpenAI API and LLM agent pipelines Automation workflows across web, mobile, and cloud Real-time systems, telephony, and event-driven architecture Earlier in my career, I led and supported large enterprise platforms and intranet migrations (Jive, SharePoint, Confluence). Today, my focus is on future-forward, human-feeling systems— vibe-coded applications: intuitive, immersive software that users don’t have to think about. If you want something that actually works in the real world—not just a chatbot—I’m happy to show live examples. menos
