Zidni Ridwan Nulmuarif — Software that feels effortless.

I build fast, friendly web and mobile apps for teams around the world, and ship my own: a video editor, a kids learning app and a handful of open-source tools.

A developer who ships.

Zidni Ridwan Nulmuarif at the Dicoding Developer Conference
Dicoding Developer Conference

8+ years building web and mobile products, from banking apps to fleet dashboards, now working remotely.

I have 8+ years of experience with HTML, CSS, JavaScript, TypeScript, Angular, Ionic, the MERN and MEAN stacks, Next.js, Vue.js, React, Kotlin, React Native, Express, MySQL, PHP and Python, with a focus on web and mobile development.

I turn analysis into products: a clear high-level overview first, then the programming languages and data structures that solve the problem.

Outside of code I like writing, reading, farming and graphic design, comedy and sci-fi films such as Interstellar and Inception, and running. I used to compete in athletics and marathons, and a healthy body keeps me productive.
