I’m opinionated, but I value a second opinion, listen well, and can change my mind, accept, and acknowledge I’m wrong when the better argument is there. **Professional Summary** Product leader with 9 years of experience across B2B SaaS with deep technical fluency and a hands-on approach to AI. T-shaped. Partner to CEO, Marketing, Sales, and Engineering. Went through project, account management, business development, customer support, marketing skins. Claude Code and Codex are my daily tools for research, PRDs, market analysis, prototyping, and faster decision-making, but I stay critical of AI's limits and outputs. I also advocate for practical AI adoption in product and developer teams. Shipped SaaS and developer products across APIs, onboarding, pricing, growth, enterprise work, and cross-functional leadership. I’m strongest when the job needs both product judgment and technical fluency. **AI and product strengths** - Team leadership: coaching product engineers, hiring Senior PMs, cross-functional execution, mentorship - AI-assisted discovery and execution: research synthesis, interview prep, PRDs, specs, prototyping, and daily use of AI coding agents - AI-native product thinking: agents, RAG, confidence models, workflow design, evaluation loops - Technical PM work: APIs, SDKs, docs, onboarding, developer workflows - Strategy and GTM: ICP, positioning, pricing, validation, customer conversations - Analytics and experiments: SQL, segmentation, behavior analysis, experimentation, self-service data querying. - Fast technical ramp-up across AI tools and concepts: RAG, RAGAS, MLflow, promptfoo, Google Vertex.
