About me

Allow me to reintroduce myself

David Choi

Software Engineer @ Orange County, CA

I eat burgers, pizza, and burritos for a living. To support my lifestyle, I attended UC Berkeley, learned how to learn, worked in sales, and eventually found my passion for web development.

I read through blogs and books to understand how to program, but found that I learned best through writing code and real life projects. I took on freelance challenges and practiced coding using online tools like Codecademy, Team Treehouse, Reddit, and Thinkful.

And now I'm a web developer specializing in branding clients and developing reusable UI components. Experienced in front end development through flexible technology solutions for admin dashboards, travel commerce, loyalty program management, online and mobile payments, branding, and landing pages. Specifically interested in development using JavaScript. I also stretched my skills by writing automation tests in Java using Selenium. I'm currently working on the UI for Solver's data warehouse cloud application built on and Angular, TypeScript, Sass to build a responsive, scalable, and performant application.

I have focused on the front end, but I enjoy all parts of the stack and I have a strong desire to continue learning new technologies and I'm always looking for ways to make myself and make my code more efficient.

Go Lakers! And Go Bears!

Shoutout to my lovely wife, our cute little pup, Morty, my ma, pa, and brah, and of course the man upstairs, Jesus Christ!
