At ioki, my team built an on-demand platform for efficient and flexible public transport systems.

A few notable responsibilities:

• Representing the Android side of things when discussing product-wide features
• Playing a big part in hiring and interviewing other co-workers
• Mentoring of new team members
• Making major contributions to modularizing the codebase
• Maintaining a state-machine-backed unidirectional dataflow approach to development

• Architecting new solutions to large-scale problems

Tieto (now TietoEVRY) is a leading Nordic IT services and software company and my first workplace. At the time I was working there, the Umeå office specialised mostly in telecom. Some of the things I did in the team were:

• Travelling abroad to train other development teams
