About

Hi, I’m Petr Kolonicz, a web developer with a passion for building scalable apps and designing information systems. I thrive in full-stack development, cloud services, and serverless architectures on AWS.

I’m experienced with hosting, internet access projects, and leading small teams. I enjoy contributing to open-source, hobby projects, and turning ideas into polished interfaces and reliable cloud solutions. I speak English (C1) and Czech (native), and I value clear communication and practical solutions.
