I build Java and Spring Boot backend services for client, internal, and personal applications. At Code Vertex Solutions, I develop REST APIs, maintain PostgreSQL and MongoDB data models, integrate third-party APIs, and deliver features with a four-member team.

I built TaskFlow Pro, a project and workflow management SaaS with Kanban boards, sprint planning, tenant-scoped access, Redis caching, and WebSocket notifications. I also built StudySync LMS to support course management, enrollments, assignments, assessments, and student progress.

For PulseHR, I developed employee onboarding, attendance, leave, payroll, asset management, real-time notifications, document storage, and audit logging. I use Spring Security, JWT authentication, role-based access control, Hibernate/JPA, PostgreSQL, Redis, Docker, and React.

Previously, I debugged Java/Spring Boot applications and delivered APIs, database models, and responsive interfaces for client applications at MT Nexus Global and Monami Technologies. I'm completing a BS in Computer Software Engineering while continuing to build production-focused backend systems.
