Leo J Barnett
Mobile App & Platform Designer


Conker "Leo was an absolute dream to work with. His constant creative ideas and probing questions helped open new ideas, lines of thought and strategy. He followed up these ideas and thoughts with very fast and professional looking wireframes. Would highly recommend.”


Tube Crush Leo completely understood my vision for the app and translated it into designs that exceeded my expectations.


He went above and beyond what I have previously experienced with UX designers by helping me devise a strategy and vision for the app once it has launched aswell as considerations for different monetisation options. 


DRIVE “Leo is a great guy and has helped us so much with very high quality work, really easy to communicate with. We love his work and are very happy, really impressed.”


Qbitt “Leo is an extremely creative and forward thinking individual, he is a pleasure to work with and brings so much energy and enthusiasm to the Qbitt project. He always goes above and beyond with his work, hitting deadlines, and doing more than what is asked! I would highly recommend him.” 


Breakr “Leo was instrumental in the design of the new look of BreakR mobile client. He quickly understood the functionality of the app and its target audience and in a very short time was able to produce an impressive design as well as improve the user experience.”




Startup enthusiast & UXUI designer who’s worked on my own projects whilst helping various other people bring their app & platform ideas to life.  I help clarify USP’s, challenge decisions and advise where I can on marketing, research, strategy and monetisation going forward.


I love working with entrepreneurs with fresh ideas. I regularly meet and discuss ventures and always find time to help wherever I can.

Having worked on various apps, I have an excellent understanding of technical requirements and can comfortably manage projects with development teams.

I’ve worked on startup projects within Dating, Influencer marketing, Networking, Booking Systems, Restaurant Services, Mobile Video, Gaming, Geo-tech, Recycling, Prop tech and Music tech.

As a startup founder myself, I understand the typical challenges we can face and am here to support all clients for the long term on the journey.
