Hi, I'm Andrey Vilchinsky 👋
AI-first Software Engineer & Product Innovator
Voice · Agents · LLM · RAG · Cloud · AI Systems
I build production-grade AI systems at the intersection of
LLMs, voice interfaces, autonomous agents, and real-world products.
Over the last 10+ years I’ve launched and scaled platforms from zero → millions of users,
served as CTO / Head of R&D, and now focus on AI-native products where intelligence is core, not an add-on.
