Ice Communications Norge AS (now Lyse Tele) is building Norway's third-largest mobile network and competes with Telia and Telenor. Ice has a range of self-developed services for handling orders, customers, messages via SMS and email, logistics, products, reporting tools, etc., which communicate via Web APIs, with each other, internal core systems, and external partners.

The services mainly run on .NET Framework and .NET Core with MS SQL Server for data storage. They are built and distributed with Cake & TeamCity and published with Octopus Deploy. Code reviews are conducted using Bitbucket.

Jonatan started his time at Ice with maintenance tasks but later participated in further development of the product MobilBytte and new development of services such as iceTrygg. MobilBytte is a "Forward Price Commitment program" with phone, subscription, insurance, and a monthly instalment included. During the project, the solution was documented with sequence diagrams together with the architect and tech lead. With shared collections and scripts in the Postman program, the team created and ran regression tests.

In the value-added services business area, Jonatan took a coordinating role as the services require changes across large parts of the organization.
