Power Planner Game

https://ldjam.com/events/ludum-dare/39/power-planner
I developed a game in 48 hours for the Ludum Dare game jam. I was the sole developer and designer for the game. The game theme was "running out of power."

The game was developed using the Unity game engine. I created building models in the blender and rendered them to the images used as 2D isometric tiles.

Unity Interactive Presentation Application

Made an education application in Unity as part of 5M employment. It allows users to create and share interactive presentations.

I was in charge of extending Unity's UI system to support project requirements. Created a lot of additional UI components such as custom buttons, toggles, switches, custom range sliders, and layout groups and also developed a system that allows the styling of UI elements via themes and custom specifications.

Improved the app's performance using Unity Profiler. Implemented a drawing engine that uses a screen pen or touches to draw vector graphics in the presentation. Implemented a sorting order system that allows users to sort objects on the page.

Unity LiDAR Camera Project

An application that allows young children to play games using a LiDAR camera. It was developed for Android devices and used on large touch screens.

Used Intel RealSense LiDAR camera and a third-party library to detect users on the screen. Developed a system for pose and motion detection. Created a custom editor that allows designers and developers to visually design the pose and motions they want to detect. The system was used in games to trigger events and answer questions.

Implemented a customizable avatar that follows the player's movements. This avatar was used in most games.

React-three-fiber Project

Implemented the front end of the application that allows children to practice school subjects while working at Zen-IT Squad. The software adapts to the children's level and allows them to improve at their own pace.

Used Three.js (React Three Fiber) to display 3D graphics on a React web page and Recoil for state management.
