I turn ideas into thoughtful, working products. Shaping everything from the words and interactions users see to the systems behind them.

Selected work

Understand the idea

I get clear on what we are making, who it is for, and what it really needs to do.
Design for security

I think about security from the beginning: who can access what, how data is handled, and what could break or be misused.
Build with AI

I use AI agents to help research, design, code, and test. I set the direction, review the work, and remain responsible for the important decisions.
Test the real thing

I test complete user flows, including the security around them. I check that things actually work and stay honest about what is proven and what is not.
