1. Project Overview:

I developed a blockchain-based framework to improve the security and efficiency of Electronic Health Records (EHR) systems. Using Ethereum for smart contracts and IPFS for off-chain storage, the framework ensures tamper-proof medical records and granular access control for patients, doctors, and administrators. Smart contracts manage operations like adding, updating, and viewing records, ensuring transparency and security. Performance tests showed strong results in execution time and throughput. This project demonstrates my ability to apply blockchain technology to solve real-world healthcare challenges, focusing on secure, scalable, and patient-centered solutions.

2. Tools Used:
- Blockchain Platform: Ethereum
- Smart Contracts: Solidity
- Off-Chain Storage: IPFS (Interplanetary File System)
- front-end Languages: JavaScript, Angular
- back-end Framework: Django

1. Project Overview:

I led a team of four in developing a women's safety app using the Android Studio Framework. The app monitors users' pulse rates in real-time during emergencies, providing a reliable safety tool. Built with a focus on social responsibility, it empowers women by offering an accessible solution for personal safety. Through collaborative efforts and expertise in Ionic, pulse rate monitoring, and backend integration, we created a robust application that addresses a critical societal need, promoting safety and security for users.

2. Tools Used:
