I found my expertise and interest in Adobe Photoshop twelve years ago, 2009. That's when I was in High School, SMKN 1 Cimahi. I was really excited in website design. I specialize in user interface. After a while, I find my self learned how to use good colors, typography, golden ratios, etc. I have created dozens of mobile application design for many clients and developer. You have to see my reviews and portfolios here. Cheers. Alvain
