Projects

AgriSathi AI | Java 21, Spring Boot 3, PostgreSQL, Cloudinary, Swagger

[GitHub Repo] • [Live Demo]

Built the Spring Boot backend for an agricultural advisory platform connecting farmers with buyers during a 30-day hackathon.
Implemented secure JWT authentication with Role-Based Access Control (RBAC) to isolate FARMER and BUYER operations.
Created REST APIs for crop lifecycle tracking, farmer profiles, and crop disease diagnosis (POST /api/v1/disease/scan) with Cloudinary media storage.
Integrated 7-day predictive weather forecasting APIs and documented 15+ endpoints using interactive OpenAPI/Swagger 3.0.

DevTinder | Java, Spring Boot, PostgreSQL, WebSockets, Railway

[GitHub Repo] • [Live Demo]

Developed and deployed a teammate matching backend in 72 hours during Devlynix Buildathon 2.0.
Designed PostgreSQL relational schemas and REST APIs for developer profiles, skill tags, and mutual connection requests.
Built real-time group and direct messaging using WebSockets (STOMP protocol) backed by persistent PostgreSQL chat history.
Configured production backend deployment on Railway with containerized environment variables and health check monitors.

LibroSphere | Java 21, Spring Boot 3, PostgreSQL, Spring Security, JUnit 5

[GitHub Repo]

Prevented double-booking race conditions on single-copy inventory by enforcing database row locks (SELECT ... FOR UPDATE) inside atomic transactions.
Built an automated FIFO waitlist queue that holds returned books for waiting members with a 48-hour pickup window before restoring general stock.
Implemented a scheduled overdue fine worker (@Scheduled) that runs nightly financial reconciliation and calculates tiered daily penalties.
Secured APIs with JWT and Refresh Token Rotation (/auth/refresh), added composite B-Tree indexes for fast queries, and wrote a 64-test automated test suite with multi-threaded stress tests (CountDownLatch).
