Hi! My name is Muhammad Hafid Khoirul.
I'm a software engineer based in Bogor, Indonesia. Currently, I'm working as a backend engineer at Qontak. I'm focused on backend technology, where I design efficient and scalable systems. My expertise includes building robust APIs, crafting optimized queries, and writing high-performance, well-tested, maintainable code.
Outside of development, I'm an amateur photographer and a writer. I enjoy blending creativity and logic in both tech and life.
