Lasse Jaara

18yo game developer from Ii, Finland 🇫🇮

I am currently studying at OSAO Kaukovainio Technical School, focusing on game programming and information technology.

More about me

Hi, I'm Lasse Jaara, a game developer who loves creating fun, player-focused games. Online, I usually go by Jupresson.

My interest started as a kid, making custom maps with my brother on the PS3 in games like Minecraft: Legacy Console Edition and LittleBigPlanet Karting.

That curiosity carried over to PC gaming, where I began building and modifying mods, plugins, and servers for Minecraft Java Edition.

Over time I moved into building full games, experimenting with Unity and Unreal Engine. My skills took a big step forward at OSAO Kaukovainio Technical School, studying Game Programming and IT, where I completed several hands-on projects.

I have developed and prototyped games using Unity and Godot, working with technologies including GDScript, Python, and C#.

My goal is to grow into a multiplayer and full-stack game developer. Right now I'm working on projects that build toward exactly that.
