What I do

I’m available for contract development, prototype / proof-of-concept work, Unity and Unreal projects, and selected longer-term product engagements.

Product developmentEnd-to-end product work across frontend, backend, infrastructure, integrations, and deployment.
Rapid prototypesFocused prototypes and PoCs for validation, funding, investor demos, and stakeholder review.
Unity & UnrealGameplay and interactive systems, tooling, world development, and backend/service integration.
Existing systemsDebugging, extending, integrating, or taking over software that already exists and needs forward momentum.

Active product

Hello World

A privacy-first school-to-school collaboration platform built around an interactive globe showing communities connecting across the world.

Unreal Engine

Kaldrune

UE5 environment and terrain work involving landscape generation, world expansion, biome development, and difficult terrain-transition problems.

R&D

Companion Cognitive Simulation

An experimental game-AI simulation system built around observed actions, memory, belief updates, and changing behavior over time.

Professional background

7+ years in production software.

I started by shipping Unity mobile games, moved into cross-platform and XR work, and then into full-stack product systems. The common thread has been taking software from build through production delivery.

Shipped mobile titles Built educational Unity games from MVP through Google Play and App Store release, including titles that reached millions of downloads.
Mobile & XR delivery Delivered Android, iOS, Oculus, and HoloLens applications, with supporting C++ plugin work, updates, and production release workflows.
End-to-end product systems Expanded into Go backends, React dashboards, AWS infrastructure, WebGL integration, real-time systems, and complete product delivery.
Case study

Puppet Academy

Puppet Academy is a private organizational education platform combining an interactive Unity application with a web dashboard and backend systems supporting organizations, assignments, performances, and reporting.

My role

Lead development across the Unity application and the surrounding product stack.

Case study

Kaldrune

A client Unreal Engine world-development project focused on terrain generation, environment expansion, biome iteration, and solving technical landscape problems as scope changed.

What I worked on
Case study

Hello World

Hello World is an active privacy-first project exploring structured school-to-school collaboration through a shared interactive globe. The public-facing work visualizes schools and communities connecting across countries while keeping children anonymous.

Current working pieces

Product direction

The project is designed around schools exchanging structured “hellos” and later participating in broader collaborative decisions or activities without turning individual children into tracked platform users.
Case study

Companion Cognitive Simulation

An experimental simulation architecture for game characters that observe player actions, retain context, update internal beliefs, and change future behavior over time.

Implemented in Go with emphasis on simulation structure, testability, constrained probabilistic behavior, and minimal reliance on an LLM for the core decision model.
