About me

Software Developer with over 2 years of hands-on experience building and maintaining web and mobile applications, with a strong foundation in Java and Spring Boot for developing RESTful APIs and backend services, alongside production experience with .NET WinForms and Node.js (ExpressJS & NestJS).

I have delivered scalable RESTful APIs and complex business logic for real-world systems — from internal project management platforms to university management and training systems — working extensively with relational databases PostgreSQL, MySQL, and SQL Server, as well as MongoDB when flexibility in data structure was needed.

I am comfortable containerizing applications with Docker, managing source code professionally using Git (following Git Flow), and consistently applying clean code practices, SOLID principles, and strong Object-Oriented Programming (OOP) concepts such as encapsulation, inheritance, polymorphism, and abstraction to design maintainable and modular systems.

With versatile technical skills spanning backend, frontend, and mobile development, a fast learning ability, and a genuine passion for creating complete, end-to-end solutions, I am ready to contribute meaningfully and grow together with your team.
