– Executed data preprocessing pipelines and managed model deployment strategies, improving system scalability and gaining hands-on experience with enterprise-level cloud architecture and CI/CD concepts. Projects

Scalable Real-Time Chat Application Node.js, React.js, MongoDB, Socket.IO, JWT

– Architected a secure, bidirectional messaging system facilitating real-time communication, successfully supporting 100+ concurrent connections with minimal latency via WebSocket protocols.

– Fortified application security by implementing JSON Web Token (JWT) authentication and bcrypt encryption for secure session handling and strict authorization across protected API routes.

– Optimized backend database performance by utilizing MongoDB aggregation pipelines and indexing, accelerating historical message retrieval times by over 40% for end-users.

– Engineered a responsive frontend utilizing React.js and sophisticated state management, deploying the full-stack architecture to cloud environments for high availability. Deep Packet Inspector Java, TCP/IP, Multithreading, Socket Programming

– Engineered a high-performance network monitoring tool utilizing Java Socket Programming to intercept, capture, and analyze 1000+ real-time incoming and outgoing network packets per minute.

– Implemented low-level bitwise operations to parse raw byte streams and decode OSI Layer 3 and 4 protocols

(TCP, UDP, ICMP), extracting critical metadata for traffic analysis.

– Boosted packet processing throughput by architecting a multithreaded execution model, utilizing thread pools to ensure high-availability network monitoring and thread-safe data handling.

– Developed a custom rule-based filtering engine to detect suspicious network traffic patterns, flag anomalous port activities, and identify potentially malformed payloads. Achievements & Problem Solving

– Mastered advanced algorithmic concepts by successfully solving 700+ Data Structures and Algorithms problems across LeetCode, Codeforces, CodeChef, and GeeksforGeeks.

– Achieved a peak LeetCode rating of 1629 (Top 15%) and a Codeforces rating of 1173, demonstrating consistent analytical and problem-solving performance under strict time constraints.
