Projects

• Match-3 Game
• RPG with sandbox creation elements
• Interactive narrative game with branching dialogue and relationship-based choices

Technical Contributions

• Kinoa SDK: Integrated and extended SDK functionality in Unity; set up in-app systems.
• FMOD: Created FMOD Studio project from scratch and integrated it into Unity. Set up SVN repository on AWS, including account creation and HTTPS port configuration.
• SQLite (SQLite3): Worked with existing Unity-integrated databases and created new ones. Built a custom encrypted database system and developed internal tools for game balance based on database-driven data.
• Core Gameplay Features: Actively contributed to core game systems (under NDA; details omitted).
• Custom Scripting Languages and Automation: Worked with two proprietary scripting languages used in Unity projects. Created automation tools, code snippets, and editor utilities to streamline development.
• Optimization: Focused on improving performance and refactoring for cleaner, faster code.

Match-3 Core Framework Development

• Contributed to the development of a modular Match-3 framework used across multiple large-scale projects via Git submodules.
• Extended existing architecture and implemented core gameplay systems and features.
• Worked with DOTween, Spine, Addressables, and Git submodules.
• Assisted in setting up Jenkins CI, gaining experience with automated builds and deployment workflows.

Cross-Project Integration and Adaptation

• Transitioned to a new team to integrate and adapt the Match-3 core framework into several distinct projects.
• Customized the framework to meet the unique requirements of each project, ensuring smooth integration and functionality.
• Developed a Plinko-style minigame and integrated Firebase and IronSource for analytics and monetization.

Unity Team Lead – Custom Multiplayer and VR Projects

VR Collaboration Platform (Oculus Quest 1 & 2)

• Led Unity development for a VR project targeting Oculus Quest 1–2 using the OVR Plugin.
• Designed and implemented the core architecture, enabling communication between Unity and backend systems.
• Integrated WebRTC for real-time audio/video communication.
• Connected Unity to Laravel and Java Spring servers via REST APIs using token-based authentication.
• Retrieved and displayed backend data securely within the VR environment.

Multiplayer 1v1 Soccer Game

• Designed and built a custom multiplayer system for a real-time 1v1 soccer game.
• Connected Unity to a Java Spring backend using SockJS with the STOMP protocol for real-time messaging.
• Implemented client-to-client communication, data synchronization, and latency handling.
• Solved network performance issues related to ping and synchronization accuracy.
• Led a Unity development team across both projects, overseeing architecture, implementation, and optimization.

• Worked on a large-scale multiplayer battle royale game supporting up to 60 players.
• Used Photon PUN for early-stage networking, later transitioned to a custom C++ server for improved performance and control.
• Developed the full audio system and animation system using Mecanim, including state machine design and trigger/event syncing.
• Implemented IK (Inverse Kinematics) and synchronized animation and audio playback across networked clients.
• Integrated models and animations in collaboration with 3D artists; ensured asset consistency and correct rig setup.
• Improved code structure and maintainability across gameplay and systems code.
• Optimized performance: implemented light baking, occlusion culling, LOD systems, and wrote custom shaders for better visual fidelity with reduced overhead.

• Designed and developed the full architecture for a VR flight simulator as part of an interactive robotic simulation system.
• Used Oculus VR SDK and HMD devices on PC for immersive simulation.
• Built a real-time system to transfer position and rotation data via sockets to external physical attractions.
• Implemented Perlin noise and factorial-based algorithms to procedurally generate large-scale terrain maps.
• Optimized performance for VR, focusing on stable framerate, minimal latency, and comfortable user experience.
• Developed all core systems, including environment generation, socket communication, and player interaction logic.
