Jonny Miles
Work with me
I've spent 10+ years leading design in startups, and now I build with AI. In this portfolio I will show how I deliver best-in-class products loved by users at scale.
I’m looking to work in teams on difficult, interesting problems that will make a huge impact in an AI-centric future.
I aim to demonstrate I am a high-agency generalist, trustable through strategy, design, and even implementation (I have a CS degree and FE dev experience).
I'll show my professional work in case studies and short overviews, but also show my self-motivation in AI, having built 10+ personal projects in the past year (300K+ users, multiple Product Hunt top 10 features).
If you think we should work together, Email me and let's arrange a chat.

Side Projects
Over the last couple of years (2023-2025) I’ve been working on lots of side projects using technologies I find exciting, such as generative AI. Some have gained thousands of users and been featured on Product Hunt.
Jonny did a fantastic job in bringing the feel of Grind into a beautiful & accessible app that is used by tens of thousands of brits.
Invaluable in every step from the product crafting process to the finishing touches of the final product, Jonny was incredibly reliable in ensuring that both Grind & the users loved the app and was specifically requested for many projects after.
A pleasure to work with as always!

GRIND
Jonny challenged our ideas in the best way, and we found a direction that landed great with our users. He was proactive, learned new tools on the fly, and did whatever it took to make the product brilliant.
Every day people tell us how much they love how the app looks and how it feels to use.
George Green
Founder
Motion
Jonny has this knack for turning complex workflows into something that just makes sense. After working with 3 designers, the peer coaching UX/UI he designed is the first one we’ve used that actually feels natural in a live session.
The reaction we get from clients is WOW I’ve never seen anything like this. It’s intuitive, simple and pleasing to the eye. He delivered fast and kept iterating as we went. He was able to take on feedback, challenge and turn it into something superior to what I had in mind.
