Bachelor of Computer Applications (BCA)Backend Development with Node.js & Express.js
Expertise in building high-throughput web APIs and transactional systems using Node.js and Express.js, including RESTful API design, token-based authentication (JWT), and payload validation.
Database Design & Optimization
Proficiency in MongoDB and SQL databases, including schema design, data aggregation pipelines, database indexing, and caching strategies to optimize query execution times and reduce database read load.
JavaScript & C/C++ Programming
Strong command of JavaScript (ES6+) and C/C++ for developing scalable backend logic, algorithmic solutions, and server-side applications with a solid foundation in data structures and algorithms.
RESTful API Design & Integration
Design and implementation of RESTful APIs supporting complex business logic, including Stripe API configurations, UPI PIN validation, and custom checkout pipelines.
Caching & Performance Optimization
Integration of caching layers (Redis) to decrease database read load and optimize query execution times by up to 40% for frequently accessed data.
Version Control & Open Source Collaboration
Active use of Git and GitHub for version control, code reviews, conflict resolution, and compliance with project style guidelines in collaborative development environments.
AI SDK Integration
Integration of Google Gemini AI SDK for automated query counseling and context tracking in web applications.
Frontend Technologies
Working knowledge of React.js, HTML5, CSS3, Tailwind CSS, and Bootstrap 5 for building and supporting frontend interfaces alongside backend systems.
Developer Tools & Platforms
Hands-on experience with tools such as Postman, Vite, npm, bun, yarn, Figma, and Chrome DevTools for development, testing, and debugging workflows.

Project history
Contributed to public GitHub repositories by reviewing and updating technical documentation, fixing markdown typos, and standardizing inline code comments. Resolved minor frontend layout alignment bugs and logic inconsistencies, submitting clean pull requests to upstream maintainers. Collaborated with active developer groups using Git version control for code reviews, conflict resolution, and compliance with project style guidelines.
Engineered a transactional ledger system with wallet debit/credit controls, establishing structural filters to prevent NaN balance exploits and double-spending. Built secure simulated checkout pipelines supporting card processing, Stripe API configurations, and custom UPI PIN validation check balances. Implemented token-based authentication (JWT) and payload validations, reducing API response times through request sanitization. Technologies: Node.js, Express.js, MongoDB, Mongoose, REST APIs, JWT.
Architected a high-performance RESTful API catalog server utilizing Express.js to process product query requests matching category-wise search queries. Integrated caching layers to decrease database read load, optimizing query execution times by 40% for frequently accessed hot-categories. Designed data pagination and aggregation pipelines in MongoDB to handle 10,000+ inventory logs with minimal resource consumption. Technologies: Node.js, Express.js, MongoDB, RESTful APIs, Redis, Caching.
