Good backend systems should remain maintainable, understandable, and reliable long after the first deployment.

I'm Alfian Nur Rachman, a backend engineer who has spent over a decade crafting server side systems that governments, utilities, and enterprises actually depend on.

My work spans from the Indonesian National Police enterprise suite to one of the country's largest utility apps. I've led teams, designed databases, and shipped architecture that handles millions of users.

Most recently focused on Golang, distributed systems, and building engineering cultures that value clarity over cleverness.

Based in Bandung, West Java, Indonesia
