Lead iOS Developer, XCode, Swift, SwiftyJSON · My client sought to modernize their earlier Obj-C app into evolvable Swift-based iOS9 iPad app. I… · More rewrote the app from scratch, while also delivering the next iteration of their roadmap. Client: Marcos was hired to re-write an existing app; this entailed fixing bugs and adding some new features. It was a pleasure working with him, always quick to respond to email correspondences, stuck to the development timeline, and really got a good understanding of how the app works in conjunction with my customers' business needs. I would definitely recommend Marcos to anyone else for app development and plan to work with him on future projects.
