Senior Product Manager blending AI/LLM platform strategy with hands-on engineering execution.
What I'm looking for
I’m a Senior Product Manager with 8+ years of product leadership and 15+ years as a full-stack engineer, focused on AI/LLM integration and platform/API products. I’m PMP-certified and Stanford PM-trained, and I bring a structured, outcome-based methodology to every engagement—whether it’s advisory or hands-on delivery.
I specialize in taking products from 0 to 1, aligning cross-functional teams of up to 15, and building GTM strategies that scale acquisition. I’ve led data-informed growth efforts (e.g., marketplace supply from 0 to 150+ freelancers) and kept teams moving with OKRs, sprint planning, and agile methodologies, improving velocity by 40%.
On the technical side, I integrate models into production features—building with OpenAI, Claude, and Gemini APIs—and I’m deeply fluent in React, Node.js, Python, REST/GraphQL, and AWS/GCP. From restructuring processes and unblocking engineering execution to building AI-powered experiences and responsible AI workflows, I bridge business outcomes and engineering reality to help teams deliver.
