About Me

I make AI products clear, usable and actually human

I’m a product designer with over 8 years of experience, focused on crafting AI interfaces that feel intuitive, clear, and trustworthy; especially in sensitive industries like GenAI, Fintech and Healthtech. Partnering closely with early-stage startups or global enterprises. I ensure technology feels human, not intimidating; so users always feel confident and in control. If you’re facing a product experience that looks more like a puzzle than a solution, that's precisely the kind of work I find most rewarding.
