What I do
I build and lead products from strategy through execution and growth — turning real problems into products that create value.
Five years building consumer products taught me to ship at scale, run rigorous experiments and connect every product decision to a measurable outcome. I work across the full lifecycle: framing the problem, planning the product, building the solution, and growing it into something sustainable.
What makes me different
I combine product judgment with the ability to build, experiment and integrate AI into real product workflows.
Most product leaders don't build. Most builders do less strategising. I do both: I can frame a market, ship a working product, run the AI evaluation infrastructure behind it, and reason about the unit economics that make it sustainable. AI is leverage I apply where it earns its place, not the whole identity.
At TikTok I built AI-powered growth features using LLMs for personalised landing pages and content optimisation, partnered with recommendation algorithm teams on user acquisition and engagement, and applied AI to growth, retention and search problems — work that led directly into building AI-native products.

What I'm looking for
Opportunities to build products that solve meaningful problems — inside a company or through product consulting and advisory work.
I'm open to senior product and AI product roles, and to advising teams on how to turn a problem into a product, especially where AI can create real leverage. If you have a hard problem worth solving, let's talk.
