During my internship, I was assigned to the software development team, where I contributed to both individual and collaborative projects. My responsibilities included setting up and managing development environments, configuring GitHub repositories, and ensuring smooth version control practices to support team workflows. I worked extensively with JavaScript and advanced into object-oriented programming concepts, applying them in practical projects such as a student management system and a telephone management system. I also developed interactive web applications, integrating APIs, implementing DOM manipulations, and applying asynchronous programming techniques with Promises and async/await. A major focus of my internship was blockchain development. I configured local Ethereum networks, designed and deployed Solidity smart contracts, and built decentralized applications (DApps) including a feedback platform and token-based reward systems. I successfully deployed ERC and ERC-20 tokens, developed an NFT contract, integrated multiple wallets (MetaMask, WalletConnect, Coinbase), and optimized gas usage by 25%. I also participated in internal security audits to identify and resolve smart contract vulnerabilities. Beyond technical work, I applied test-driven development (TDD) and regression testing to ensure reliability and scalability of applications. I regularly presented project progress to supervisors, collaborated with team members on integration tasks, and engaged in peer knowledge-sharing sessions to strengthen team performance. This experience equipped me with hands-on expertise in Web3 development, smart contract engineering, and modern web technologies, preparing me to contribute effectively to blockchain-based solutions in real-world environments.
