4K Download had five desktop apps used by millions of people, and most of the UI still carried years of legacy decisions. I led design across the core suite, several new products, and a tighter cross-platform experience on Windows, macOS, and Ubuntu.

I spent most of my time on the parts that move numbers: onboarding, paywalls, control panels, and making the main flows easier to read. I also proposed and shipped a built-in browser. Daily engagement rose about 18%, and the product stopped feeling like a download-only tool.

By the time I moved on, the suite had passed 60 million users. The apps looked cleaner, shared more structure, and were easier to extend without rewriting everything from scratch.
