  7. Cihat Gündüz

    Cihat Gündüz

    iOS & Rails-Developer, User Interface Designer

    Germany - Tests: 1 - Portfolio: 3

    English: Studying Computer Science at Karlsruhe Institute of Technology since 4 years I have already developed 7 apps on my own of which you can find the latest by searching for my first name "Cihat" on the App Store for iOS. For my apps I developed backends using Ruby on Rails which I now have a lot of experience with for using as an API and doing calculations on user data on the cloud. Last but not least I worked on 6 more Apps for customers who contacted me, which was a lot of fun so I decided to go for Freelancer.com. Looking forward for my first experiences here! Deutsch: Ich studiere nun schon seit 4 Jahren am Karlsruhe Institut für Technologie das Fach Informatik und habe nebenher bereits sieben verschiedene eigene Ideen als Apps verwirklicht. Diese Apps findet man schnell im App Store für iOS-Geräte, wenn man meinen Vornamen "Cihat" in der Suche eingibt. Für meine eigenen Apps lernte ich neben der iOS-Entwicklung zusätzlich die Entwicklung von Backends mithilfe von Ruby on Rails, worin ich mich jetzt gut auskenne. Damit bin ich im Stande APIs mitsamt Berechnungen in der Cloud basierend auf Nutzerdaten zu entwerfen. Zu guter Letzt habe ich noch an sechs weiteren Apps von verschiedenen Kunden gearbeitet. Da mir das ziemlich viel Spaß gemacht hat, habe ich mich entschieden, es auf Freelancer.com zu versuchen. Jetzt warte ich gespannt auf meine ersten Erfahrungen hier!
