Hi, I'm Christien — a full-stack developer building fast, modern web products with Next.js and TypeScript, including interactive maps and 3D data visualizations with Mapbox, MapLibre, and Deck.gl.

A selection of projects highlighting my engineering approach and problem-solving. From concept to delivery, each build is designed to be performant, maintainable, and a pleasure to use.
Code that brings ideas to life. 💻
I help teams turn product ideas into reliable, well-crafted web and mobile experiences — built to scale, and a pleasure to maintain.
I'm a Full Stack Developer with 4+ years of hands-on experience in React.js, Next.js, TypeScript and Laravel. I excel at converting design concepts into functional, responsive applications across web and mobile platforms.
I focus on designing performant, maintainable and scalable applications—crafting clean interfaces with modern tools while ensuring seamless integration with backend systems.
Having mentored junior developers and worked in diverse teams, I combine technical skill with strong collaboration. Let's partner to build engaging digital solutions that address real challenges!
My journey started with a Dell laptop that could barely keep up with me. Builds were slow, my workflow was constantly stalling, and most days it tested my patience more than my code. But I refused to let it discourage me. I told myself: "This slow laptop is going to earn me a better one."
So I kept going. I leaned on every tutorial, doc, and community I could find, and I built — line by stubborn line. The beginning was hard, but my passion for this craft pressed me forward when nothing else would. Today, that old Dell is long gone, my setup is sharper, and so am I — but the journey continues.
The Stack I Build With
The languages, frameworks, and cloud tools I reach for to ship fast, scalable web apps — plus the mapping and 3D libraries behind my interactive data visualizations.
Experience that delivers. 😎
From concept to completion, I combine design thinking with thoughtful execution to help brands move forward with innovative and effective solutions.
