Hello! I’m Insan, a Site Reliability Engineer with 6+ years of experience building reliable and scalable systems across industries, including technology, energy, and telecommunications.
I’ve worked in corporate and startup environments, collaborating with professionals from diverse backgrounds. These experiences exposed me to both modern and legacy technologies and deepened my understanding of various business processes.
I don’t limit myself to specific tools; I focus on fundamentals like data structures, algorithms, computer architecture, networking, and distributed systems. This helps me learn new technologies quickly and solve complex problems effectively.
I speak English, Japanese, and Indonesian.
