• Mentored team members on proprietary GPU specifications, native ISA assembly and graphics APIs.
• Utilized AI developer tools for technical research, test authoring and code implementation.

Tiusanen Consulting Oy

Provided independent consulting across graphics API validation, conformance test authoring, and game systems.

• Siru Innovations (Khronos Vulkan CTS): Subcontracted to implement and validate Vulkan API test cases in C++ inside the official Khronos Vulkan Conformance Test Suite (CTS) for core graphics features and SPIR-V compliance.

• Implemented a custom particle system for the company's proprietary mobile game engine.
• Built a 3D audio system with platform-specific backends for iOS and Android (OpenAL).
• Consulted for Next Games, implementing combat systems, unit movement behaviors and custom Unity 3D editor tooling for the mobile title Blade Runner Rogue.
• Worked on game-client and server-side implementations for the mobile title Nitro: Drift Racing (Unity 3D, GameSparks, MongoDB, JavaScript).

Kuuasema Ltd

Developed commercial client titles across both the studio's proprietary C++ engine and later Unity 3D.

• Extended the proprietary translation toolchain (compiling Java game logic into native C++, Objective-C and Flash) and implemented asynchronous file I/O preloading.
• Lead Programmer for both Nokia's Modern Mayor (Windows Phone, C++/Java) and the interactive TV broadcast game Midaksen kosketus (Intervisio, C++/OpenGL).
• Programmed tactical combat systems and gameplay for Sanoma & Disney's The Duckforce Rises (Unity 3D, C#) on iOS and Android.
• Lead Programmer for Fortum Clean Power (Unity 3D), delivering an interactive energy grid simulation and educational application.

Star Arcade Ltd

Engineered core multiplatform C++ libraries and network abstractions for mobile multiplayer titles.

• Designed and implemented a cross-platform UI widget system atop the proprietary C++ OpenGL ES engine, powering multiplayer titles including Jelly Wars, Reversi and Star Diamonds.
• Implemented native network socket abstractions for Linux (Maemo/MeeGo) and integrated mobile OAuth sign-on (Google+ and Facebook).
• Set up and maintained build automation tooling, Subversion (SVN) code repositories and Bugzilla.

IGIOS Ltd / Alternative Games / Silverquill

Delivered native Linux ports of Windows-only commercial games in the pre-Proton era, translating Direct3D to OpenGL.

• Co-founded IGIOS Ltd (2007): Delivered native Linux ports of Frozenbyte's Shadowgrounds and Shadowgrounds Survivor (OpenGL, SDL, OpenAL), and built a cross-platform 3D presentation tool with Blender Python export scripts.
• Co-founded Alternative Games Ltd (2010): Developed the Linux game launcher and installer for Frozenbyte's Trine.
• Co-founded Silverquill Ltd (2010): Developed an XML-to-Lua/C# branching dialogue system and skeletal animation loading (Assimp) for Iron Sky: Operation Highjump.

University of Jyväskylä (Information Management Centre)

Developed web applications and custom database-driven backends for academic and administrative operations using Python, Plone, Zope and Google App Engine.

Early Engineering • Database & Simulation Design

• Agora Virtual Environment Center (2004–2005): Participated in the development of a heavy truck driving simulator for immersive 3D CAVE projection environments using C++ and OpenSceneGraph.
• University of Helsinki Center for Microfilming and Conservation (2000–2007): Developed an application for attaching metadata to OCR-processed newspaper pages (later integrated into commercial software) and wrote Perl scripts for filtering data before database import.

War Engine

A custom C++/OpenGL real-time strategy engine featuring heightmap-based modifiable terrain, custom shaders and Blender exporters for map and 3D asset data.

Ratz

An old pet project of mine: a retro game targeting Windows, Linux, and macOS, utilizing OpenGL and OpenAL, combining pixel art with custom shaders, simple physics, and positional audio.

Recently modernized the C++ codebase and added game controller support using local AI tooling (Ollama / Qwen). I still actively work on it and intend to publish it eventually.

VGA Mode 13h & x86 Assembly Experiments

Early experimentation of real-time gameplay and graphics/physics code with Mode 13h graphics using a mix of x86 assembly and Object Pascal.
