I build end-to-end web and mobile experiences with a strong foundation in web architectures, responsive interfaces, and robust RESTful APIs. I’m especially drawn to turning complex engineering challenges into clean, usable products by pairing practical full-stack development with LLM system integration.

As a Research Development Intern at IIT Mandi IKSMHA Centre, I developed interactive React Native (Expo) modules for an ITIHIHAS story generation LLM project, delivering component-based UI that stays focused on user experience. I also integrated FastAPI microservices with PostgreSQL using Supabase authentication to implement protected routes and secure JWT session management.

In my earlier Web Development internship, I built and deployed responsive, mobile-first websites using HTML5, CSS3, Bootstrap, JavaScript, and PHP, with strong cross-browser compatibility. I integrated RESTful endpoints and optimized rendering metrics to improve initial page load times and overall performance.

Security was also a key part of my growth during a Cybersecurity internship, where I performed hands-on Web Application Vulnerability Assessments and Penetration Testing (WAPT). I documented detailed mitigation checklists and security reports grounded in OWASP Top 10 exploits, network configurations, and Linux environments.

On the project side, I engineered a cloud-based code review platform that enables real-time code collaboration with secure role-based access control using Firebase Authentication and Express APIs on Google Cloud Platform. I also built an ITIHIHAS story generation LLM application with a modular React Native architecture, secure prompt transmission through FastAPI connector APIs, and Supabase JWT-based client navigation for dependable, protected UX.
