Hardware-Aware Graphics Engineering & Systems Architecture

Founded by Mikko Tiusanen, Tiusanen Consulting Oy delivers specialized low-level engineering and systems architecture backed by over two decades of commercial shipping experience, based in Helsinki, Finland.

The trajectory began with early-2000s simulation systems and data processing (Agora CAVE heavy truck driving simulator, University of Helsinki), leading to co-founding IGIOS Oy in 2007—pioneering native Direct3D-to-OpenGL engine conversions (Shadowgrounds, Shadowgrounds Survivor) in the pre-Proton/pre-WINE era with custom POSIX runtime layers and OpenAL spatial audio backends.

Over subsequent years, Mikko architected proprietary engine runtimes, cross-platform translation pipelines, and core gameplay subsystems for international studios and productions, including Disney Mobile Studios (The Duckforce Rises via Kuuasema), Nokia (Modern Mayor), Next Games (Blade Runner Rogue via Reforged Studios), and Frozenbyte (Trine via Alternative Games). Most recently, following the acquisition of Siru Innovations, he spent 4.5 years on the Intel GPU Core Team, authoring ISA-level functional and performance verification tests across GPU microarchitectures and developing native Vulkan/D3D12 API capture tooling.

Mikko operates as a hands-on technical architect rather than an abstract advisor—combining twenty years of systems perspective with the capability to write, debug, and optimize bare-metal C++ and native GPU ISA that maximizes physical silicon throughput.
