“I don't design games. I design worlds that can grow games inside them.”
Worlds Made to Be Lived In, Not Just Played
I design technical systems that simulate living worlds — adaptable, expressive, and built for collaboration.
Rapid implementation to test ideas, simulate gameplay feel, and bring interaction concepts to life.
Prototype
A category spanning shaders, custom rendering, and camera effects—technical design work that defines atmosphere, lighting, and the feeling of a world.
Visual Systems
Editor extensions and pipelines designed to boost creator efficiency and optimize the systems that support dynamic, living content.

Celestial Cycle
-
Celestial Cycle is a modular Unity toolset that simulates immersive world elements sky, weather, seasons, ocean, and AI cycles through procedural, time-based control.
-
It helps developers build dynamic environmental experiences effortlessly, letting them focus on gameplay while the system handles visual and behavioral transitions across time and space.
CC: Time of Day
Time of Day in Celestial Cycle manages seamless transitions across morning, noon, evening, and night by dynamically adjusting lighting, environment settings, and atmospheric effects. Using a fully custom procedural Skybox—without relying on cubemaps—it controls the sun, moon, stars, and clouds in real-time. This creates a living sky that evolves naturally, enhancing immersion and artistic direction.
CC: Dynamic Nature
Dynamic Nature simulates weather and seasonal changes that directly impact your world. Snow accumulates, rain soaks objects, and fog rolls in—all in real-time. Post-process settings shift with seasons, from warm autumn tones to desaturated winter hues. Cloud density and sky behavior adapt fluidly with Time of Day, creating a reactive environment that feels alive and deeply immersive.
CC Dynamic NPC
Dynamic NPC brings characters to life by anchoring them in the world’s rhythm. NPCs follow schedules and change behavior based on time and role—working, resting, or wandering as the world turns. With the iTalk system, each character has thoughts, personality, and voice. They don’t just react; they belong, engaging in context-aware conversations that reflect who they are and the world they live in.
Work in Progress
CC: DynamicOcean
Dynamic Ocean is a scalable ocean simulation built with AAA techniques—Gerstner waves, planar reflections, and subsurface scattering—all optimized to run even on mobile. It reacts seamlessly with Time of Day and Dynamic Nature systems, reflecting sky, weather, and season. With buoyancy, splash FX, and wetness shaders, it transforms water into a living system, ready for anything from stylized mobile games to high-end PC experiences.

Personal Project
Unity
Mobile Controller System
This project began as a simple character controller. Then came flight. Then combat. Then destruction. Inspired by the thrill of Iron Man’s mobility, this solo-built system features real-time flying, shooting, hovering, and physics-based interactions with enemies and environments. It’s not just a tribute—it’s a playable dream.

Advanced Resource Checker
Unity utility script that scans and verifies the presence of critical assets, components, or references in a project. Designed for development and QA pipelines, it helps identify missing resources before runtime, streamlining debugging and ensuring smooth deployment across complex Unity scenes or modular systems.
Advanced Remove Color Tool
Advanced Remove Color Tool is a Unity Editor extension that detects and removes specific colors from textures or materials within the scene or project. Ideal for cleaning assets or applying visual consistency, it provides an intuitive UI for precise color targeting, replacement, and batch processing.
Advanced Object Grid Spawner
Advanced Object Grid Spawner is a Unity Editor tool that lets you quickly populate environments with objects in a customizable grid layout. It supports spacing, randomness, rotation, and prefab selection, making it perfect for prototyping levels, building modular worlds, or unleashing mass mayhem (politely arranged).
Advanced Object Manager
Advanced Object Manager streamlines the process of tracking, activating, and organizing game objects within your Unity scenes. Ideal for managing large quantities of interactive elements, it includes toggles for visibility, grouping, and quick edits—giving creators control over chaos with a click.
