About John

Hello! I am an IOS Swift & Objective C software developer. I offer my talents to best support you in your projects!

I master the Objective-C and Swift languages. In a few days your idea will be developed!

I am currently looking for IOS mobile application projects/contracts of any duration. I master different design patterns such as MVC or MVVM as well as more complex ones such as VIPER (Clean Archi).

I have 7 years of experience acquired within start-ups and large groups (Media, Banking, Health, Transport, Automotive...)

In addition to IOS development, I would be delighted to contribute in part or in full to the design of your application. I love this creative part!

The daily rate varies depending on the size of the project.

My various experiences in start-ups have allowed me to develop the skills that will meet all your needs (geolocation, social network login, data persistence, chat...).

See you soon,

John
