A fresh start here. 2026-10-28 https://www.polysign.lu/updates/six-months-of-building/ Over the past six months, I’ve had the chance to work on a diverse mix of projects: mobile apps, games, and new SaaS products. That variety is the reason for this rebuild. I wanted a place that puts the work front and centre, with space to share what I’m making and the ideas behind it. There’s more on the way, too. I’m building educational tools and apps that I’ll be showcasing here very soon. Take a look around. This is where I’ll share what comes next.
