About Me

I am a Computer Science student focused on backend development and on building practical projects that strengthen my skills in web applications, databases, authentication, and software organization. Through personal projects, I have been developing applications with real features such as CRUD operations, dashboards, filtering systems, pagination, recurring data logic, and deployment workflows. I am currently looking for my first internship or junior opportunity where I can contribute, learn continuously, and grow in a professional development environment.

What I Deliver

Backend foundations with real structure

Applications built with authentication, route protection, validation, organized logic, and a strong foundation for scalable backend development.

Data-driven web applications

Practical systems with CRUD operations, database integration, filters, pagination, dashboards, and features designed around real user workflows.

Portfolio projects with real-world thinking

Projects developed not only to practice syntax, but to demonstrate business rules, usability, deployment, and problem-solving in realistic application scenarios.
