⦁ Designed a unified project architecture on VContainer and migrated the codebase from
Task/Coroutine to UniTask for consistent cross-platform behaviour — critical for WebGL. New
games and trainers were spun up significantly faster on the shared foundation.
⦁ Built a Trainer Builder with a creation wizard that let level designers author new training
Skills/Tools
scenarios from existing templates — removing engineers from the content pipeline entirely. Languages & Core
⦁ Developed a node-based dialogue system with in-node voice-over, events and branching C# / .NET, OOP, SOLID, Design
endings — designers shipped custom-ordered educational games with no engineering Patterns
involvement per title.

⦁ Created a multi-platform AssetBundle build tool: batch-builds for several platforms in one
Unity 2D/3D, iOS/Android, Editor
pass, with platform tags, custom suffixes and content inspection. Integrated localization
bundles into the same pipeline with ScriptableObject drafts and 15-second autosave for power- Tooling, Plugins integration,

⦁ Built a generic tutorial overlay system: clones the current screen, resolves target elements by
component keys, and cuts them from the dimming layer with a shader mask plus pointer
arrows and text — any screen becomes tutorial-ready without bespoke code. Education
