A senior product designer who designs for outcomes.

Eight years turning research into interfaces — and interfaces into numbers that move.

I'm a senior product designer with 8+ years across B2B and B2C SaaS. I design the interface — but I judge it by what it does after launch: adoption, retention, the metric that actually moves.

I run projects end to end. Qualitative research and data analysis to find the real problem, design across web and mobile, clear handoffs for engineering, and usability testing or A/B experiments to prove the work before anyone calls it done. Most of my wins started as a research finding, not a design brief.

Most recently I led product at Wordwall — owning strategy, OKRs, hiring and mentoring alongside the design. That stretch into the business is what makes me a sharper designer: I read the roadmap and the metrics as fluently as the interface, so design decisions hold up where it counts.

Outside work, you'll find me traveling, reading, and baking a sourdough bread.

How I work

Problems before pixels

Decisions come from user research and data, not the loudest opinion in the room. I set up continuous research where it didn't exist.

Proven, not assumed

Usability testing and A/B experiments decide what ships — including the experiments that fail and send me back to iterate.

Insight to handoff

I own the whole arc: framing, ideation, design across platforms, and developer-ready specs — with the business case in view throughout.
