Profile

Technical × product profile. I design and develop AI solutions that go to production: AI agents, automations, and LLM integrations. My role: turning business requirements into concrete, integrated, usable deliverables — bridging business, product, and tech to avoid unrealistic specs and projects that fail in production. With 10 years in web development and project management, I work end-to-end, from product vision to delivery — on any stack — with an AI-assisted workflow (Claude Code, MCP).
