About

I'm a Product Designer with 4+ years of experience building SaaS products across design and engineering. I began my career as a software engineer before transitioning into UX and product design, giving me the ability to bridge user needs with technical implementation. I designed and shipped features for a PPC management platform used by digital marketers and agencies worldwide. My work spans user research, interaction design, data visualisation, prototyping, and front-end development. I enjoy simplifying complex systems into accessible experiences and collaborating closely with cross-functional teams from discovery through delivery. Oh and, I also scribble and have my publication.

Preflight - A preflight checklist for product decisions.

Preflight is an AI skill that helps product teams make better decisions before investing engineering time. Instead of jumping from problem → solution, Preflight helps teams validate whether they are solving the right problem, evaluate evidence behind decisions, compare solutions and understand risks before rollout. Built as a reusable AI skill for Claude Code and OpenAI Codex. Preflight does not replace product judgement. It helps teams ask better questions and make more informed decisions.
