For the last 10 year iOS has been my primary focus and work environment. Ranging from Objective C to Swift and API communication to Animations.
In working in different startup environments I have accumulated a good understanding of Android and the Android eco system. From Java to Kotlin and the Android SDK.
I have experience in working with backend systems and API design in several languages and environments such as Go, PHP, Ruby, Python, Node.js, AWS and Heroku.
Working in startups means conceptualizing, designing and implementing all in one.
