My Portfolio Site
This is a portfolio site created to give a quick overview of what I can do in terms of design and animation. Created at the start of my freelancing career, it was what gave me most of my jobs in freelance. A combination of NextJS, TailwindCSS and Framer Motion.

Anime Workout App
Created a Next.js web app for working out with your favorite characters, made into an APK, and uploaded to the Google Play Store. Currently at 100,000 downloads.

I made the app from start to finish, including the back end, front end, design, animations, and marketing.
