About Me

I'm Fadhil Hanri Kamarz, a Web and iOS Developer based in Jakarta.

My academic background is in petroleum engineering, but my passion lies in technology. Driven by the philosophy of "Do what you love", I transitioned into software development. I started my journey by learning HTML and JavaScript because the tools were lightweight, highly accessible, and run on any laptop.

Today, I specialize in building local-first applications, native mobile architectures, and custom data parsers.
