Mobile DEV

I work as a mobile developer for the last decade. Have worked on several big apps both published internally or in the app-store. I have a lot of experience in building user-friendly apps and love to think around with the users / designers to create the best possible solution for them. You can checkout my CV to see the projects I have been working on.

Cloud DEV

Integrating systems, authentication, backend, automatic deployments. Clouds give so many advantages to build complex systems easier and faster. I have used the Microsoft Azure cloud in many of my projects to solve these kind of challenges. Highly interested in the possibilities that the cloud can bring to software development.

Backend Dev

Optimising data for mobile apps is important. As data that’s not necessary to send or receive will optimize the user experience for the end-user. Especially in locations where the internet is not a given. I have worked on several backend to write stable and fast backend. Also integrated several existing systems in apps. If it has an API I can work with it.

PROBLEM SOLVER
