Derrick Koo

Front-End Developer, JavaScript Engineer

Intro

Hello! I’m a front-end developer based just outside sunny Denver, Colorado. I’m currently a Lead Front-End Engineer at 10up, where I help build products for clients small and large, including some of the biggest names on the web.

I strive for accessibility, performance, clean code, smooth user experiences, and elegant application architecture. If you’d like to talk about code or potential projects, please get in touch.

Areas of Expertise

HTML, CSS


I’ve been building websites for fun, education, and career since the days of GeoCities and MySpace. I discovered HTML and CSS while noodling with custom blogs in college, and have been hooked ever since.

JavaScript


JavaScript is my bread, butter, and jam. I’ve worked on large-scale applications using frameworks such as React, React Native, Ionic, Angular, Meteor and Backbone, and am always hungry to learn more.

WordPress


WordPress is one of the most powerful and extensible open-source content management systems on the planet. I’ve been building WordPress sites of all shapes and sizes for well over a decade.

Lore

I was born and raised in New York, and bounced around Manhattan, Brooklyn and Queens for most of my adult life.

Prior to joining 10up, I was a member of the Editorial Production team for seven years at The New Yorker, where I was part of the team who migrated newyorker.com to WordPress from a proprietary CMS.

In a previous life, I majored in history at Columbia and earned a master’s degree in journalism at NYU. I strongly considered pursuing a career writing and reporting in the city before answering my true calling to write code in the mountains.
