Experience
CookUnity

In my time there, I went from coding an iOS app to hiring 15+ Devs, QA, etc. with whom we built most the application from scratch, based in Node.js, GraphQL, and React.
MiTelefe
http://telefe.com/mi-telefe/My role consisted of the following:
TECHNICAL LEAD
I had to take action and decide how a new feature/requirement would be laid out so that we could use existing architecture at a maximum and re-utilize our existing codebase to sprint as fast and solid as possible
iOS TEAM LEAD
I designed and coded the architecture for how was the app going to be laid out, giving different tasks to each of the devs and helping where needed.
The app was written in Swift 2.2, already migrated to Swift 3.0. Used Cocoapods and a series of in-house frameworks used for live interactive content and connection to our back end. Livestreaming is provided by Akamai with auth tokens, video pre-roll using Google's IMA, and AdMob ads between content. VOD streaming in HLS.
