Message

At Data V Tech, I developed C# backend systems for business logic, data processing, and cross-system integration on the ERP Epicor System. I also optimized SQL Server queries in large, long-running systems to improve performance and response time.

On the Resume Management System project, I analyzed business requirements, designed the database, and developed application-review features across the backend and frontend. I also developed a university management application with WinForms and Oracle, including user accounts and role-based permissions.
