BUG BOUNTY - Spotify iOS SDK failing with error

Roman was great, knowledgable, friendly, and was able to adapt when unforeseen bugs arose in my project. Would definitely recommend to anybody who needs iOS help!

One screen five features- scroll, swipe, tap to open menu, Tap to transition to new screen, tap hold drag to reorder

Roman is a highly knowledgeable developer, which I would refer to him for hard difficult issues. He communicates well and is fluent in English. He is willing to make any changes until you are satisfied. He would have received 5 stars for all categories, if he was more available and unfortunately this slowed the work down.

Most definitely would hire again. Completed the project before the deadline and up to and beyond what I asked for. Also completed the work for a very reasonable price.
