| Full-Stack Software Engineer & Blockchain Architect | I am a final-year B.Tech Computer Science & Engineering student with a specialized focus on Blockchain Technology. My expertise lies at the intersection of traditional high-performance computing and decentralized systems. I build "Web 2.5" solutions—marrying the speed and UX of modern web apps with the security and transparency of the ledger. With a rigorous academic background in Data Structures, Algorithms, and System Design, I don't just write code; I architect scalable digital products from the ground up. 1.Full-Stack Engineering: Expert-level development using the MERN/PERN stack (MongoDB/PostgreSQL, Express, React, Node.js). I build responsive, SEO-optimized, and high-conversion frontends paired with robust, RESTful, or GraphQL APIs. 2. Blockchain & Web3 Ecosystem: Advanced Smart Contract development in Solidity and Rust. Experience with DeFi protocols, NFT architecture, and DAO governance. I prioritize gas optimization and rigorous security testing using Foundry and Hardhat. 3. Backend & DevOps: Proficient in Python (Django/FastAPI) and C++. I handle cloud deployment via AWS/Google Cloud, containerization with Docker, and CI/CD pipeline management to ensure seamless delivery 4. System Design & Security: Deep understanding of distributed systems, cryptography, and database normalization. I focus on building "security-first" applications to protect user data and digital assets. My technical foundation is built on a diverse and powerful stack. On the language level, I am proficient in Solidity, JavaScript (ES6+), TypeScript, Python, C++, and SQL. For frontend development, I build immersive and responsive user interfaces using React.js, Next.js, Tailwind CSS, Redux, and Three.js. My backend expertise covers Node.js, FastAPI, PostgreSQL, Redis, and MongoDB, ensuring scalable and efficient data management. Within the Web3 ecosystem, I leverage Ethers.js, Web3.js, IPFS, Chainlink, and OpenZeppelin to create secure decentralized solutions. Finally, my workflow is supported by a robust set of tools including Git, Docker, AWS, Linux, Hardhat, and Foundry, allowing for professional-grade deployment and testing. "My goal is to provide enterprise-grade code that is clean, maintainable, and future-proof. Whether you need a complex DeFi platform or a high-traffic SaaS application, I deliver technical excellence."…

    paper ChainLinker: Decentralized Project CrowdFunding Hub

    ChainLinker is a decentralized crowdfunding platform built to eliminate the “black box” of traditional fundraising. By leveraging Ethereum smart contracts, ChainLinker ensures that every donation is transparently recorded on-chain and that funds are only accessible to the verified project owner. This removes the need for high-fee intermediaries and provides donors with absolute certainty regarding where their contributions are held.

    Creators deploy a crowdfunding campaign by providing a title, description, and goal amount.

    All project data is stored within a Solidity smart contract on the on the blockchain.

    Funds are held by the contract itself. The withdrawFunds function uses a strict require check to ensure only the project’s owner address can claim the raised crypto.
