ZTX is a large-scale Web3 virtual world platform where I joined as an early engineer (2022–2025), working remotely with a US-based company while living in Korea. I contributed to the original Unity3D multiplayer version featuring housing systems, resource loops, crafting, and full character customization tied to on-chain ownership.

My work spanned gameplay systems, backend-connected data flows, customization frameworks, and modular architecture. As the product shifted to mobile, I helped transform ZTX into a fashion-focused app where users buy, create, and compete with blockchain-backed digital outfits, collaborating asynchronously across US and international teams.

In my current position, I develop advanced real-time virtual production systems for a K-Pop virtual idol production environment using Unreal Engine and Unity3D. This includes motion-capture pipelines, facial and body tracking, and live camera systems for virtual idol performances and digital livestreaming.

I build custom tools, optimize multi-device workflows, and integrate real-time animation and character systems. My work bridges engineering, creative production, and motion-capture technology to enable high-quality K-Pop virtual idol performances and broadcast-grade digital character livestreams.

Contributed to Kippo, a US-based social gaming and dating app known for its avatar system, gamified UI, and strong community features. Worked on Unity-based components supporting interactive profiles and user engagement systems.

Collaborated with a California startup team to develop features for a highly stylized, game-inspired mobile experience used by hundreds of thousands of users.

Unraveled is a narrative-driven RPG successfully funded on Kickstarter and created in collaboration with composer Hiroki Kikuta (Secret of Mana). I led Unity3D development, building the core gameplay, atmosphere, and storytelling systems for the tech demo.

The project focuses on emotional storytelling and dreamlike environments, exploring themes of trauma and imagination. My work shaped the technical foundation and creative direction that brought the world to life.

I developed the initial Unity3D version of the 21CC App, integrating Moodle API, TinCan API, and custom backend systems to support interactive training games and job-skills modules.

The platform later evolved into an Angular-based solution used in the Netherlands, India, and Thailand. My work included gameplay development, backend integration, and guiding the technical transition of the platform.

A set of Unity3D mini-games created to engage young people with logistics careers. I developed the gameplay loops, UI flows, and backend integrations in collaboration with DB Schenker and ADR organizations.

The project was showcased at the UN High-Level Political Forum on Sustainable Development in 2019 and became a major early development milestone for the 21CC App.

Whisper of a Rose was the commercial debut of RosePortal Games, reaching the #1 New Release spot on Steam. I developed the entire RPG experience — gameplay systems, UI, graphics, and storytelling structure.

The game is known for its emotional narrative and dreamlike worlds, resonating strongly with players. It remains one of the studio’s signature titles with fully custom-designed assets.

A series of Unity3D training games developed for Olympia and Albert Heijn to streamline onboarding and enhance employee performance. I built the gameplay, scoring systems, and analytics integration.

The modules are part of the 21CC App and are actively used for real-world training. My work contributed to reducing onboarding costs and improving skill development.
