1. JobsSync – Automated CI/CD Pipeline for a Three-Tier Java Maven Application. Designed and deployed a three-tier Java Maven application with an automated CI/CD pipeline, ensuring smooth integration, testing, and deployment using Jenkins and AWS. ● Configured Jenkins pipeline for continuous integration and deployment, automating build, testing, and deployment. ● Containerized the application with Docker and pushed images to Docker Hub for versioned deployments. ● Deployed the application on AWS EC2, using secure SSH authentication and automation scripts. ● Stored and versioned application artifacts (WAR files) in Amazon S3 for reliable storage. ● Implemented automated rollback strategies in case of deployment failures. ● Configured email notifications for build and deployment status updates. Technologies: Jenkins, Docker, AWS (EC2, S3), Git, Maven, Shell Scripting, Linux. 2. Automated CI/CD Pipeline for my Personal Portfolio. Built and deployed a personal portfolio website with an automated CI/CD pipeline that streamlined code changes from GitHub to a live application on AWS EC2. ● Configured GitHub Actions for continuous integration and deployment, automating build, test, and deployment processes with every code change. ● Containerized the application using Docker, ensuring environment consistency across all stages of development, testing, and deployment. ● Managed Docker image storage and versioning on Docker Hub, facilitating efficient image updates and rollback management. ● Deployed the portfolio site on AWS EC2 using a self-hosted GitHub Actions runner, enabling efficient, automated updates without manual intervention. Technologies: GitHub Actions, Docker, AWS EC2, React, Vite. 3. Decentralized Transaction Web3 Application. Developed a Web3-based decentralized application (dApp) that enables secure and seamless Ethereum transactions between wallets, leveraging smart contracts and blockchain technology. ● Built a user-friendly frontend using ReactJS and Tailwind CSS, ensuring an intuitive and responsive interface. ● Developed Ethereum smart contracts using Solidity, implementing functions for secure and verified transactions. ● Integrated Web3.js to interact with the Ethereum blockchain, enabling real-time transaction updates. ● Implemented MetaMask authentication for secure wallet connections and decentralized identity verification. ● Optimized gas fees using smart contract logic to ensure cost-effective Ethereum transfers. ● Deployed the smart contract on a testnet (Ropsten/Goerli) for testing, ensuring robustness before moving to mainnet. Technologies: ReactJS, Solidity, Web3.js, Tailwind CSS, Ethereum Blockchain.
