Skills

What I do, with one example from my work.

Research & discovery

When JOTA looked for new opportunities, client interviews showed what was missing. It became a paid product with 43+ corporate clients.

Analytics & growth

Post pages held 81% of active users, so that's where I tested subscription CTAs: 4K subscribers in three months.

B2B workflows

I redesigned the tool clients use to manage their newsletters so they could do it on their own, and tested it with 20 people before launch.

Design systems

At JOTA I'm tightening handoff and design QA, so what engineering ships stays consistent with what was designed.
