About me
Hello, I’m İbrahim Qarayev, a backend-focused software developer specializing in Java and Spring Boot.
I build RESTful APIs and backend systems using modern development practices, applying object-oriented programming (OOP), clean code principles, and layered architecture to create maintainable and scalable applications.
I focus on writing secure, reliable, and well-structured code while continuously improving my skills in backend development, software architecture, and modern technologies.
What i'm doing
-
Backend development
I build scalable and maintainable backend applications using Java and Spring Boot, following clean code practices and layered architecture principles.
-
RESTful API Design
I design and implement RESTful APIs with well-structured requests and responses, input validation, and effective error handling.
-
Microservices Architecture
I design and develop microservice-based systems using Spring Cloud, focusing on scalability, service communication, and system resilience.
-
Secure Application Development
I implement authentication and authorization using Spring Security and JWT (JSON Web Tokens), applying secure coding practices to protect applications and reduce potential vulnerabilities.
-
Database Design & Management
I work with relational databases such as MySQL, PostgreSQL, and Oracle SQL, and write efficient queries and database logic using PL/SQL. I also use Redis for caching and performance optimization.
-
Messaging & Asynchronous Processing
I use Apache Kafka to build event-driven and asynchronous systems that improve scalability and reliability.
-
DevOps & Infrastructure
I containerize applications using Docker, manage database migrations with Liquibase, and work in Linux environments.
-
Testing & Code Quality
I write unit tests and integration tests to ensure application reliability, maintain high code quality, and support long-term maintainability.
-
Version Control & Collaboration
I use Git along with GitHub and GitLab to manage source code, track changes, and collaborate effectively on projects.
-
Continuous Learning
I continuously improve my backend development skills by learning new technologies, following best practices, and building real-world projects.
