I worked on systems for JP Morgan, State Farm Insurance, American General Group, and many other financial service firms. I have developed iPhone applications and designed and built a iPhone mobile ecommerce system for a startup similar to Uber. I know CSS3 and have implemented highly detailed pixel perfect user interfaces.
