I fix expensive Unity production problems and build developer tools for large iOS and Android games.
I have 13+ years in game development, including Unity Technical Lead and Principal Engineer roles at Playtika. My work focuses on scalable Unity architecture, developer velocity, release safety, mobile performance, CI/CD, and AI-assisted engineering workflows.

- Designed a development quality system for a 2M+ line Unity codebase that enabled release cycles as short as 3 days and reduced major defects found after code freeze to one or fewer.
- Contributed to two US Top-10-grossing and six US Top-100-grossing mobile titles, including a product operating at approximately 1M DAU.
- Led Unity architecture, platform modernization, developer tooling, CI/CD, release-quality, and performance initiatives across multiple teams.
- Conducted 300+ technical interviews and helped build two internal Unity academies.
| Project | What it solves |
|---|---|
| XUUnity MCP | A local-first, validation-first MCP server for safe Unity Editor automation. It supports compile checks, EditMode and PlayMode tests, scene assertions, console inspection, snapshots, and Game View screenshots. |
| DevAccelerationSystem | Unity tooling for compile-matrix validation across build targets and scripting-define combinations before expensive builds or CI failures. |
| TheBestLogger | Production-oriented Unity logging with structured output, remote configuration, and controlled debug activation. |
| AI Research Hub | Reusable AI engineering workflows, prompts, roadmaps, and operating models for repository-attached Unity development. |
| SKUnityPackages | Earlier Unity Editor productivity packages for editor coroutines, menu discovery, and scripting-define management. |
