What agency partners and founders say about working with me.
Johnnie has an incredible ability to turn vague ideas into clear, usable products. The right questions come up early, which saves so much time down the line.

Elena Marks
Head of Product, Fintech startup
Working with Johnnie felt like having a design partner, not just a vendor. Johnnie pushed back when needed and always had the user's best interest in mind.

James Okafor
Founder, Bright Path
The design system Johnnie built for us completely transformed how our team collaborates. Everything is consistent, scalable, and just makes sense.

Priya Nathan
Engineering Lead, Vantage Health
Johnnie's attention to detail is unmatched. Things don't just look good, they work better.

Marco Ferreira
CEO, Loop Commerce
We came to Johnnie with a messy, half-finished product. The whole experience got rethought, and our engagement numbers reflect it.

Sofia Lindqvist
COO, Northwind Studio
Johnnie is one of the few designers who truly understands both the craft and the business side of product design. Highly recommend.
