About

Full-Stack Software Engineer | Passionate Problem Solver | MERN Stack & DSA Expert I’m a dedicated Software Engineer with 1.5+ years of hands-on experience building scalable, user-centric applications using the MERN stack (MongoDB, Express.js, React.js, Node.js, Typescript) and a strong foundation in Data Structures and Algorithms (C++). Previously, at Upaav AI, I built a productivity app from scratch, integrating JIRA APIs and optimizing task-tracking efficiency by 30%. My projects showcase my ability to deliver impactful solutions: from "PayPocket", a secure money transfer app with JWT authentication, to "Movie Arena", a Netflix-like platform with Firebase and Stripe integration, and "Rain Vine", a real-time weather app powered by OpenWeatherMap API. With a B.Tech in Electronics and Communication Engineering (CGPA 8.13/10) from Guru Nanak Dev University, I’ve solved 1100+ LeetCode problems (max rating 1705) and secured a global rank of 1855 in LeetCode BiWeekly Contest 151. My technical toolkit includes C++, Java, JavaScript, React.js, Node.js, Express.js, Typescript, SQL, AWS, and more, paired with a knack for collaboration and mentoring (guided 60+ students in DSA). I’m eager to contribute my full-stack expertise and problem-solving passion to innovative SDE or Full-Stack Developer roles. Let’s build something extraordinary together! 📩 Connect with me: harcharansingh198400@gmail.com
