Experience

CMore

• CMore Entertainment is a subscription television service in the Pan Nordic region.
• My first job, while working for Accedo Broadband AB, was creating the new iOS streaming app which allowed users to watch CMore content. Initially, I began work on the project as a secondary (support) developer, but later on, I became the lead developer and continued developing it until 2013.
• The current live app is still based on the code we've written.

NBCU SeeSo

• SeeSo was an OTT-subscription-streaming service (2016).
• While working for Accedo Broadband, I led the team that developed the iOS application. As the web and iOS were the first two platforms to be released, we worked in close cooperation and laid down the basic architecture of the product which could successfully accommodate several additional mobile and TV platforms.
• Unfortunately, it was shut down in November 2017 and I worked with the product team until the end.

OSN WAVO

• WAVO is OSN's new OTT-streaming service.
• This was my last project at Accedo while working with the Smart TV team. We developed the new client application for LG webOS and Samsung Tizen operating systems.
• The service is only accessible in the Middle East region.
