About Me

Software Engineer based in Magelang, Indonesia

I'm a software engineer with 7+ years of experience in full-stack development, specializing in JavaScript, React, Next.js, Node.js, and cloud technologies. Currently working at Alpha Red Solution and Eduqat, I build scalable solutions for hospitality and education technology platforms.

I'm passionate about building scalable applications, mentoring junior developers, and staying updated with the latest technologies. When I'm not coding, you can find me exploring new tech stack, contributing to open-source projects, or enjoying a good cup of coffee ☕.
