Rajiv Kumar

Hi, I’m Rajiv — a passionate Full Stack Developer and engineering student with a strong drive to build tech that solves real-world problems. I specialize in React.js, Firebase, Node.js, and have hands-on experience with MongoDB, Solidity, Ethers.js, and IPFS for building decentralized applications. I have a strong foundation in Data Structures and Algorithms (DSA) and am currently diving into system design to further strengthen my backend and architectural knowledge.

I participated in the Diversion2k25 MLH Hackathon, where I built Decentralized DigiVault — a blockchain-powered DigiLocker using React, Firebase, Polygon, Smart Contracts, IPFS, and Machine Learning to securely store and verify documents. It was an intense 36-hour experience that pushed my boundaries and taught me the value of fast-paced collaboration and execution.

Some of my other key projects include:

🧠 AI Interview Coach – Simulates job interviews using AI and provides real-time feedback

💬 Full Stack Chat App – Secure, real-time messaging platform with token-based authentication

🌱 Plant Disease Detection App – Uses CNN & Deep Learning to classify plant diseases from images

🚿 Smart Watering System – Arduino + Blynk based real-time soil moisture monitoring and automation

I’ve interned as a frontend developer on an education platform using React, and I was selected as a contributor in GirlScript Summer of Code. I’m always eager to explore new technologies, build impactful projects, and collaborate with developers who share the same passion for innovation.
