Professional Summary

Remote-first Senior Technical Product Manager and AI Product Leader with 10+ years scaling Web2, Web3/DeFi platforms, algorithmic trading systems, and Generative AI solutions.

I specialize in turning complex technical requirements into AI-driven products that deliver measurable business impact. At Protofire I currently own the full product roadmap for privacy wallets, lending protocols, and enterprise blockchain integrations (Aave, Uniswap, Lido, Prisma), while building internal AI Agents and LLM-powered tools using Claude, Grok and n8n.

If you’re building the next generation of AI-native products, intelligent trading systems, or decentralized infrastructure — let’s talk. I ship fast, speak fluent technical and business, and love turning 0→1 ideas into revenue-generating reality.
