Production-grade ride-hailing REST API in Spring Boot 3.3.1 with a layered Controller–Service–Repository architecture — 5 JPA entities and 10+ endpoints covering the full ride lifecycle (request, accept, start, end, payment, rating).

• 🔐 Secured every endpoint with JWT + Spring Security; resolved a Railway ↔ Vercel CORS production outage in under 2 hours via a global CorsConfigurationSource
• 🐳 Containerized with Docker and wired up CI/CD for automated deploys to Railway on every main push

Java Spring Boot React PostgreSQL Docker CI/CD

Full-stack MERN travel booking application built with MVC architecture, JWT auth, bcrypt password hashing, and an admin dashboard with full CRUD over tour packages.

• 🛡️ Role-based access control with protected routes across client & API layers, spanning 3+ MongoDB collections
• 🚀 Deployed via CI/CD to Vercel

MongoDB Express.js React.js Node.js JWT

On-chain voting application with full unit test coverage via Truffle & Ganache — every vote tied to a unique wallet address, with voter eligibility (18+) enforced directly inside the Solidity contract.

• 🦊 Integrated with React via Web3.js for MetaMask wallet auth and one-click vote submission with on-chain confirmation

React.js Solidity MetaMask Ganache Unit Testing

Software Developer Intern · Code Eater — Remote, Delhi · Aug 2023 – Oct 2023

• Designed and deployed 3 Ethereum smart contracts in Solidity using OOP principles, covering 6+ on-chain operations; wrote unit tests on Ganache achieving full function-level coverage
• Integrated contracts with a React frontend via Web3.js & MetaMask; applied gas-optimization techniques (loop refactoring, storage packing, re-entrancy guards) cutting estimated gas costs by ~15%
• Worked in an Agile team — sprint planning, daily stand-ups, and a clean Git branch strategy across feature/release branches on Linux
