Work

01 — Featured

Real-time Enterprise Messaging Engine

A real-time messaging backend. Migrated from STOMP to Native WebSockets to cut per-message protocol overhead, built a thread-safe ConcurrentHashMap router for constant-time message delivery, bound Spring Security auth at the HTTP handshake to prevent identity spoofing, and decoupled background work behind Spring’s ApplicationEventPublisher. Deployed via Docker on Render CI/CD.

Hospital Management System

Stabilized and hardened an MVC-restructured hospital system. Fixed a privilege-escalation vulnerability, rebuilt a broken bcrypt password-hashing flow, repaired broken JOIN queries across patient/doctor/ward modules, and reconstructed 22 missing view files from Git history. Tested locally on XAMPP, deployed publicly on InfinityFree.
