My Project

Decentralized Game Asset Registry
ERC-1155 Blockchain System

A decentralized application designed for managing in-game digital assets by separating on-chain ownership from off-chain metadata. The system implements the ERC-1155 token standard to efficiently manage both fungible and non-fungible items within a single smart contract. A custom MetadataRegistry maintains the tokenId → URI mapping, while the backend built with Express serves metadata as JSON and hosts asset images. The frontend, developed with Vite and Web3.js, interacts with the smart contract through MetaMask on the Sepolia test network.

Nas Coffee
Android Coffee Ordering System

A modern Android coffee ordering application designed to provide a customizable barista-style ordering experience. The app includes secure offline authentication using password hashing with SHA-256 and salt, combined with encrypted local storage. Menu data and order history are managed using Room Database, while the application follows the MVVM architecture pattern to ensure scalability, maintainability, and a clean separation of concerns.

Energy-Efficient Bipedal Walker
Reinforcement Learning Project

A reinforcement learning project focused on training an agent to walk in the BipedalWalker-v3 environment while optimizing for energy efficiency. The agent is trained using Proximal Policy Optimization (PPO) with Stable-Baselines3. Custom reward shaping techniques were applied, including energy-per-progress metrics and smoothness penalties. Performance was evaluated using the Cost of Transport (CoT) metric and the total distance traveled.

Smart Trash Can Automation
Arduino IoT Prototype

An IoT-based smart trash can prototype built using Arduino, an ultrasonic sensor, and a servo motor. The system automatically detects nearby objects and opens the lid for a short duration, minimizing physical contact. This project demonstrates a simple automation solution aimed at improving hygiene and user convenience in everyday environments.
