I design products and build them, working between design and engineering. I prototype in code and sweat the detail until things feel right in the hand. I design user-friendly products with clarity, collaborate openly, and build with care.
Lately, I’ve been building apps and running experiments with AI, and more and more, opening pull requests alongside developers on GitHub.
Selected work

Formidable HR
Formidable HR brings people tools to the Formidable platform. As the product designer, I shaped event types, status chips and moments like work anniversaries, from first sketches to the shipped interface.

Songmark
Songmark is an iOS app that gathers the music I save across YouTube, Shazam and SoundCloud into one library. I designed and built it end to end, from the share sheet to crates and previews.

Luma
Luma is a macOS app that reads blood test results and turns them into simple guidance on what to eat. I designed and built it, from parsing the reports to the daily food suggestions.
Experiments

About
It started with a news story about Hollywood actors being photoshopped to look better.
I was intrigued enough to go find Photoshop CS4. A cracked unlicensed copy, obviously.
I never really stopped.
We didn’t have internet at home, so I paid by the hour at an internet café to download fonts, brushes, and stock images, then went home and used them until I could afford to go back. Most of what I made was Counter-Strike forum signatures. A few of them were genuinely good.
These days I’m the only designer across two products, which means I own the whole thing: strategy, research, interface, and the design system underneath it. I like it that way.
I sit between design and engineering. I prototype in code, sweat pixel-level detail, and care more about whether something works in someone’s hands than how it looks in a presentation. Lately that’s meant taking a product from a one-line idea to a near-finished thing on my own.
Same obsession as the café days. Better tools.
