Who am I?

Think of me as a code-wielding samurai, slicing through bugs and crafting clean, efficient software. I am Jonas Nikolopoulos, a full-stack developer obsessed with building, breaking, and optimizing until everything runs like a well-oiled katana.

When I’m not in the code dojo, I’m at the gym, hunting great food, or geeking out over Japan. Always learning and improving, because great code, like mastery, is a lifelong pursuit.

jstack Website

We rebuilt 3 key pages of jstack’s WordPress site using Next.js, Tailwind CSS, ShadCN, Contentful, and my Webkit. The design stayed the same, but the new setup is faster, cheaper, and easier to maintain.

Android Anime App

I built a simple anime app in May 2024 for my UI2 course at KdG using Android Studio, Kotlin, and Jetpack Compose. It was my first time using Kotlin, and even though the UI was basic, I learned a lot from the project.
