I am a UX designer with an emphasis on psychology and UI elements. I am currently working on a startup myself but have helped others improve their conversion rates and general UX experiences. You can see my personal site at http://yoshyosh.com
All UX can be improved, regardless if it is physical or digital. I have been working on UX related problems for the past 3 years and have learned how to code last year to leverage it even further.
I am working on a site called usechisel.com which has a lot of new UI paradigms users need to get used to. Because of this I am a lot more sensitive to how users need to learn and use new products. If you need feedback about solving a certain UI/UX problem feel free to book a call.
