Parama Math 2, 3, and 4
My first job out of university.
Joined a small studio of primarily 3 part-time IT consultants that had started making and already released a Year 1 math game on the side of their normal business. As the first installment had some success, they were looking for help with the game side of things for future installments.
Ended up working there for 1½ years, and helped make math games for kids in years 2, 3, and 4 of Swedish elementary school.
Being at such a small studio gave me the opportunity to wear several hats at once very early on, getting experience with not only Game Design but also writing, playtesting, studio recordings with voice actors, producing and scheduling, packaging assets for launching on stores, etc. Needless to say I learned a lot of things during my time there, and I look back on that time very fondly.
