Sheng was amazing — 10/10 recommend working with him. - Great communicator: I always knew where things stood, timelines, etc. - Talented web dev: I made a bunch of technical requests, he nailed them all. - High sense of ownership: He volunteered to clean up some of my UX/UI before we got started, just to make sure everything was looking great. - Super flexible: I made a few design changes late in the process and he rolled with it. TL;DR: Hire Sheng, you won't be sorry!
