Frontend Engineer

Ruth Andiswa Sitinga

Frontend engineer who builds interfaces that feel alive.

I build products in React and TypeScript, then tune the small stuff — motion, timing, feedback — until an interface responds like something breathing under your cursor.

About

Ruth Andiswa Sitinga

I'm a frontend engineer who thinks in React and TypeScript, with Node.js for the backend work that supports it. I care about the moment between an action and its response — the hover, the load, the transition — and I build with the belief that good engineering is what makes an interface feel like it's paying attention to you.
