01. About Me

Background & Specialization

Profile Photo

I'm an IT Administrator and Full-Stack Software Developer focused on building practical digital systems for real-world business needs. My work spans enterprise application development, databases, REST APIs, system integration, and software deployment.

I work primarily with Java and Spring Boot on the backend, alongside React and Next.js for modern web applications. I place strong emphasis on clean architecture, reliable data models, maintainable code, and software that can evolve as business requirements change.

My experience also extends to IT infrastructure and system administration. I work with Windows and Linux environments, Docker, databases, networking, deployment infrastructure, and technical support, allowing me to take software from development through deployment and ongoing operation.
