I’m a Computer Engineering student (BE Computer Engineering) with an average CGPA of 8.8, focused on turning core CS fundamentals into production-ready software. My coursework across Data Structures and Algorithms, Operating Systems, Computer Networks, and Database Management Systems keeps me grounded in practical performance and reliability tradeoffs. I enjoy shipping clean APIs and interfaces that stay fast, secure, and maintainable.

In my ExaltaSoft Web Development Internship, I developed and deployed 3+ client-facing web applications for hotels and B2B businesses using the MERN stack. I revamped a hotel booking platform with a modern React-based UI and optimized backend APIs, increasing traffic from 5k to 15k requests/month. I also built RESTful APIs with Express.js and integrated MongoDB with optimized queries and indexing, reducing average response time by 20%.

During my TCS iON GATE-2024 and GATE-2025 contract role as IT Manager, I managed technical operations for high-stakes examinations. I set up and managed 150+ examination systems with stable, secure, and isolated execution, and I diagnosed real-time issues to reduce system lockdown periods by 30%. I supported onboarding and registration workflows and coordinated with TCS ION teams and on-site staff while strictly following operational protocols.

My projects reflect how I love working beyond “just the UI”: I built a Mesh VPN System using Go with WireGuard, STUN/ICE, and UDP hole punching for NAT traversal, plus relay fallback servers for reliability. I also created LabMate-AI, a Spring AI-based Retrieval-Augmented Generation assistant integrating Ollama-LLMs and pgvector to achieve 85%+ response accuracy and cut lab query resolution from 5 minutes to under 10 seconds. And with CargoStacks, I designed a scalable inventory management system using Java, Spring Boot, and SQL (including MySQL) with role-based access control and optimized data retrieval.
