I'm a B.Tech student specializing in Java backend development using Spring Boot and Spring Security. I enjoy building secure, scalable RESTful systems and contributing to real-world open source projects.
- 🔭 Currently building CampusConnect — a full-stack university networking platform
- 🌱 Learning Advanced Spring Security, System Design, and Docker/CI-CD
- 🛠️ Contributed a merged fix to OpenAPI Generator (20k+ ⭐)
- 💬 Ask me about Java, Spring Boot, JWT Auth, REST API design
- 📍 Based in India
OpenAPI Generator — 20k+ ⭐ · Merged PR
One of the most widely used API code generation tools in the industry.
- 🐛 Fixed critical enum naming bug — preserved
SCREAMING_SNAKE_CASEvalues correctly in Java client generation - ✅ Added targeted test coverage to prevent regression
- 📈 Improved code generation consistency across multiple language targets

Full-stack university networking and resource-sharing platform
What it does: Students upload notes, PYQs, assignments, and interview experiences. Admins moderate content. Advanced filtering + pagination for resource discovery.
Backend highlights:
- JWT auth with BCrypt password hashing + Role-Based Access Control (STUDENT / ADMIN)
- Cloudinary integration for file storage
- 15+ REST endpoints across Auth, Resources, and Interview modules
- Pagination, search & filter by branch, semester, subject, college
- Global exception handling via
@ControllerAdvice - Swagger/OpenAPI documentation
- Deployed on Render (backend) + Vercel (frontend) + Railway (MySQL)

Secure REST API for personal task management with JWT authentication
What it does: Users register, log in, and manage their personal tasks. Every task endpoint is protected — only the owner can access their data.
Backend highlights:
- Stateless JWT authentication with filter chain
- Full CRUD for tasks with user-scoped data isolation
- DTO abstraction to decouple API layer from entity layer
- Bean Validation with meaningful error responses
