Ansh Oberoi

I am a full-stack developer focused on building scalable, secure, and performance-optimized web applications.

I have hands-on experience developing end-to-end systems using React, Node.js, Express, and MongoDB. My work includes designing REST APIs, implementing JWT-based authentication, secure password hashing with bcrypt, database optimization, and writing clean, maintainable backend architecture.

Key highlights of my work:

• Built a ledger-based banking backend with atomic balance updates, idempotent transactions, JWT authentication, token blacklisting, and secure credit/debit APIs.
• Developed an AI-powered Chrome extension that summarizes PDFs/webpages and dynamically generates MCQs and flashcards to enhance learning efficiency.
• Created a full-stack property booking platform with authentication, booking management, and location-based search integration.
• Engineered a secure feedback collection system with analytics, encryption, and optimized database handling.

I have solved 500+ Data Structures and Algorithms problems and secured 1st place in a competitive IEEE coding competition, demonstrating strong problem-solving ability and algorithmic thinking.

My interests lie in backend engineering, scalable system design, AI-driven products, and cloud-based architectures. I enjoy taking ownership of features end-to-end — from designing the database schema to deploying production-ready APIs.
