Experience
Role
Expense Tracker
Engineered a full-stack expense management system achieving secure multi-user transaction storage by designing RESTful APIs with Node.js/Express.js and MongoDB, applying system design fundamentals for scalable client-server architecture. Improved database query performance by ~30% by implementing MongoDB indexing and optimized CRUD operations, applying time and space complexity analysis to reduce query overhead from O(n) to O(log n). Developed a modular financial dashboard supporting real-time expense categorization across 10+ categories by building reusable React components following Object-Oriented Programming principles. Enhanced application maintainability and scalability by architecting a layered backend with clean RESTful API separation and Express middleware, enabling future feature additions with minimal refactoring. Streamlined collaborative development across 5+ feature branches by enforcing Git workflows with structured code reviews, reducing merge conflicts by ~40%.

Role
WebChat – Real-Time Messaging Application
Built a real-time chat platform supporting instant message broadcasting to 50+ simultaneous users by implementing bidirectional WebSocket communication via Socket.IO, reducing message latency to under 100ms. Reduced server-side processing overhead by designing event-driven algorithms for message routing, enabling O(1) broadcast complexity to all connected clients. Architected a scalable client-server system supporting concurrent WebSocket connections by applying system design principles including separation of concerns and stateless RESTful API endpoints for non-real-time operations. Accelerated UI rendering speed by 25% by implementing React state-driven interfaces with reusable component abstractions following Object- Oriented and component-based design patterns. Increased backend reliability by structuring Express middleware as modular request handlers, enabling independent unit testing of API routes and WebSocket event listeners.
