"I have known and worked closely with Jessie for over 4 years and she is amazing. She is detailed oriented, yet quick and extremely savvy about the technical intricacies of mobile and web-based development. She has done a complete redesign of my company's mobile app, has designed our website, and has designed another website from a prior company which was very complicated as it had to interface with another company's geo-location API. I highly recommend Jessie."
