What began as side projects has grown into JExcellence—a journey of crafting enterprise-grade applications with the power of Once UI.
Can you tell a bit about yourself and how you got into coding?
I'm Justin, 25, from Germany. By day, I work as a full-stack developer at a company that builds web-based financial software for municipalities. Right now, I'm part of the automatic testing team, making sure everything we ship is reliable and solid.But really, my journey with code started way before that. I've been programming for over a decade — first as a hobby, and for the last couple of years more officially through my own company.
4-6 hours
Spent coding after work
It all began with Minecraft. I was following tutorials, tinkering around, until I noticed a plugin nobody had ever built properly. That challenge kept me busy for six years. I even ran a full Minecraft server powered entirely by plugins I wrote myself. My very first website came out of that too: a trading auction system connected to the server.
From there, things slowly grew. I picked up my first contract doing WordPress sites, then got curious about new frameworks and tried out everything I could — Vue, Angular, React, and more. Somewhere along the way, I realized I was spending 80% of my day coding. Sometimes I built useful tools; sometimes I just experimented with random ideas. I made plenty of mistakes, fixed them, and kept going.
That's still how I approach programming today: with curiosity, a willingness to try new things, and the drive to turn side projects into something bigger.
What kind of side projects did you first use Once UI for?
I first came across Once UI while building a simple beauty site for a client. I wanted the design to look clean and professional without spending weeks reinventing layouts and components. Once UI made that process smooth — I could focus on content and flow instead of pixel-perfect styling.
