I start with what people actually say, and build from there.

I’m Toni. I listen first, then design.

I’m a product designer and researcher. I design for Porsche, and I run HearHere, a podcast app I make on my own.

Research is where I start. Before I open a design tool, I read: interviews, reviews, support emails. I’m looking for the thing people keep saying in different words. Almost every design decision I make can be traced back to one of those.

Then I make it real. I like working across the whole thing, from the first conversation to the shipped build. I prototype early, test with real people, and would rather fix what’s already there than add something new.

I build my own tools. When the tool I need doesn’t exist, I make it: a research agent that tracks competing apps every week, a feedback inbox that turns urgent emails into tasks, and an MCP server that connects AI assistants to Things. I also write, most recently a paper on where conversational UI works, and where it doesn’t.

Say hi. If you’re building something and want a designer who starts with the people using it, email is the best way to reach me.
