About
Ibnu Sofian Firdaus
Software engineer from Indonesia, currently at Mekari. I've worked across e-commerce, logistics, and SaaS — building backend systems, internal tools, and things that handle real scale.
I care about writing code that other people can read and understand. I enjoy thinking through system design, career growth, and the lessons that only come from shipping things in production.
Outside work: reading, writing this blog, and occasionally convincing myself to exercise.
