Backend-Focused Full Stack Developer.

Hi, I'm Sarah Nurhaliza

I architect powerful backend systems and bring them to life on the web — building from the core out, with clean logic and elegant interfaces.

Who I Am

About Me

I'm a Semester 4 student at CEP-CCIT FTUI (Faculty of Engineering, Universitas Indonesia), specializing in Full Stack Development with a deep focus on Backend Architecture, Web Development, and Mobile App Development.

My passion lies in understanding how systems work at their core — building robust, scalable backend logic and connecting it seamlessly to the web. I believe a great developer doesn't just write code; they design systems that stand the test of time.

Like a butterfly, I'm always evolving — transforming challenges into elegant solutions. Like a sunflower, I grow toward the light: always learning, always reaching further.

"The best architecture is one you never have to explain."
