Hey — I'm Chris, an iOS engineer from Vietnam. I spend most of my working hours thinking about the infrastructure side of mobile development: build systems, CI pipelines, developer tooling, and the quiet problems that slow teams down before anyone notices.

This blog is where I think out loud. On the tech side, I write about iOS, Swift, and the engineering decisions behind maintaining mobile infrastructure at scale. I'm more interested in how I reasoned through a problem than just presenting the answer — so most posts read more like an investigation than a tutorial.

I also write personal essays in Vietnamese, mostly under the Chuyện Nghề series — honest reflections on career, craft, and what it actually feels like to work in this field for years. That side of the blog is quieter and more personal, but it matters just as much to me.

Glad you found this corner. Hope something here is useful — or at least honest.
