Buy Mario Iseli a coffee

Explorer, lifelong learner, camper/vanlife enthusiast, and occasional indie hacker. I build open-source tools, tinker with infrastructure, and teach the next generation of nerds — mostly fueled by curiosity and an unreasonable amount of coffee. Your donations help me stay independent: new lab gear, weird side projects, and the freedom to keep learning out loud. I genuinely appreciate every contribution.

And yes — a solid chunk will literally become coffee. The habit is real. ☕
