// About Me
I'm a Computer Science graduate and software developer with experience building backend systems, web applications, and cross-platform mobile apps. I enjoy turning ideas into reliable, maintainable software.
My work includes developing RESTful APIs, authentication and authorization systems, payment integrations, relational databases, and responsive web and mobile applications. I also integrate AI services to build intelligent features and automate workflows.
While backend development is my primary focus, I'm comfortable working across the full stack to deliver complete, scalable applications from database to user interface.
I enjoy building software that solves practical problems, learning new technologies, and continuously improving how I design and develop applications.

Backend Developer Intern
Developed the backend architecture and core business logic for a logistics management system, implementing RESTful APIs, authentication and authorization, order management, shipment tracking, and role-based access control. Built separate operational workflows that enabled administrators to manage carriers, agents, and all orders, while restricting agents to the management of assigned orders. These features streamlined logistics operations, improved shipment visibility, and established a secure, structured workflow for managing deliveries from customer registration through final destination.
Mobile App Developer
Developed and maintained cross-platform mobile applications. Implemented core application features, integrated backend APIs, managed application state, optimized performance, and built responsive user interfaces to deliver reliable and intuitive mobile experiences.
Backend Developer
Developed and maintained backend systems by designing RESTful APIs, implementing authentication and authorization, building business logic, managing relational databases, and integrating third-party services. Worked closely with frontend development to build scalable, maintainable, and high-performance applications while optimizing data workflows and overall system reliability.
Fullstack Web Developer
I have built and deployed several full-stack projects, including MarketCore and EduMate (SaaS apps), as well as interactive web apps like Snake Game, Dice Game, Drum Web App, and Blog Web App. My experience covers designing databases, developing backend and frontend functionality, and creating complete, working applications from scratch.
