About me

I'm a Finnish ICT student specialized in game engine programming. I have a huge passion for all audio related things from creating and implementing sounds to developing relevant applications. My goal is to specialize professionally in audio programming. I'm always ready to try and learn new things and do my best whatever task or project it is.

Skills

During the past 3 years, I have developed a good understanding in C/C++ and created projects with many different programming libraries and APIs. In my portfolio section you can find some of my C/C++ work, like a 2D/3D game engine project and a cross-platform audio API project that I was a part of. I've also done some UI projects in the past with Qt and ImGui.

Unity has been my main game development platform for over 6 years and I've used it in multiple game projects and jams. In addition to Unity, I have also done some game projects with Unreal Engine, Defold and Urho3D.

Python has been a great general problem-solving language and automation tool for many of my projects. I have also gotten familiar with some prototyping enviroments and platforms, like Arduino and MATLAB.

This portfolio site is developed using Bulma CSS framework and Node.js packages, like gulp.js.

Here's some projects what I've done

Audio API for Linux
I was part of creating cross-platform audio API for Ruskatek Oy. I was working on the Linux side and took advantage of ALSA API. The company uses the API in their game engine and other customer projects. I also created WAV file parser for playback testing purposes.
I learned: Linux environment, C, ALSA API, audio buffers and WAV file parsing.
Computer vision project
I was part of researching ways to find reflecting areas from photos of wood surfaces. The project was done by me and one of my friend and it was a school project that was made in association with Raute Oyj. The method we researched created specular maps from image sequences with OpenCV library.
I learned: OpenCV, C/C++, feature detection and matching, image processing, lens correction, homography techniques and teamwork.

Spatial audio game demo
I created an Unity game demo as a school assignment that tested Steam Audio spatial audio library. The demo tested Steam Audio's HRTF, sound occlusion and sound reflection capabilities. The goal in the game demo was to collect 5 keys from a maze with the help of 3D sound clues before the time ends.

I learned: Spatial audio libraries, Unity (C#) and maze generation algorithms.
Unity multiplayer game
I was part of creating 3D multiplayer hide-and-seek game "Reef Chase" as a school project. My role in the team was to add multiplayer functionality to the game by using Unity's UNet network system. I was also adding gameplay features and helping other programmers in problems.

I learned: Unity, C#, UNet, HacknPlan/Kanban and teamwork

2D/3D game engine
I've been developing a 2D/3D game engine with OpenGL and SDL that has been used in many school projects. The first version was 2D game engine that had game object positions and rotations, sprite rendering and input handling. I've also created a simple 2D demo with it. I'm currently developing the next version that is using entity-component-system architecture and 3D rendering.

I learned: OpenGL, SDL, GLSL, game engine architectures, rendering pipeline and image loading
