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 product roadmap for privacy wallets, lending protocols, and enterprise blockchain integrations (Aave, Uniswap, Compound, Balancer, 1inch, Lido, Prisma), while architecting internal developer tools, Agentic AI automations, and complex workflows using n8n and LangChain. I also led ecosystem product development for the Midnight Foundation (blockchain explorer, telemetry, and web app).

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.
