I am a Java Backend Developer with strong skills in building web applications using Java EE technologies. My core technical stack includes Java, JSP, Servlets, JDBC, and MySQL. I have experience developing full-featured web applications from scratch, including user authentication systems, real-time voting systems, and database-driven platforms.
I am proficient in writing clean, maintainable code following MVC architecture. I have worked extensively with Apache Tomcat for application deployment and have experience configuring and managing MySQL databases. I am also familiar with HTML5, CSS3, and JavaScript for frontend development.
I am currently expanding my skills in Spring Boot to build RESTful APIs and microservices. I understand the importance of code security and implement best practices such as password hashing, session management, and SQL injection prevention.
I have completed more than 10 projects during my studies, ranging from simple landing pages to complex web appl

项目经验
Project 1: Online Voting System
I developed a secure and transparent online voting system using JSP, Servlets, and JDBC with MySQL database. The system supports user registration, secure login with password hashing, real-time vote counting, and an admin panel for managing candidates and elections. I implemented session management to prevent duplicate voting and designed a responsive user interface using HTML5 and CSS3. The project was deployed on Apache Tomcat and is available on GitHub.
My role: Full-stack developer – I handled everything from database design to frontend implementation and backend logic. I ensured the system was secure by encrypting sensitive data and using prepared statements to prevent SQL injection. The system also includes real-time election timers, candidate filtering, and detailed election results.
This project showcases my ability to build a complete web application with Java technologies and deliver a working product from start to finish. It demonstrates my understanding of user authentication, database connectivity, data security, and server-side logic. I also implemented role-based access control for admin and regular users.
Project 2: E-Commerce Website (Python)
I am currently developing a fully functional e-commerce website using Python. The project includes product catalog management, shopping cart functionality, user authentication, order processing, and an admin dashboard. I have implemented search and filter features to improve user experience and am integrating a payment system for real transactions.
My role: Lead developer – I designed the database schema, built the backend logic, and created the frontend interface. I ensure smooth user experience and secure data handling. This project has given me commercial experience in understanding client requirements and delivering solutions.
Both projects demonstrate my technical versatility, attention to detail, and ability to deliver results independently. I am passionate
