Profile

As a software developer, I have practical experience creating secure backend solutions, microservices architectures, and scalable systems. Projects ranging from full-stack DevOps microservices and database-driven apps to encrypted Java chat apps have motivated me to concentrate on clean design, modular code, and effective problem-solving. I thrive in environments that challenge me and encourage ongoing growth.

Programming excites me because it involves solving complex problems and creating scalable solutions. I enjoy streamlining algorithms, improving system architecture, and exploring frameworks and languages such as Java, JavaScript, SQL, Dart, and Python. My journey started at 16 when I developed a game, igniting my lifelong passion for software engineering.
