Hi, I'm Pavel Kalandra.
Software engineer and engineering leader based in Prague.
What is this page?
kalandra.tech is my personal website, but it's also an experiment. I'm building it transparently — every version, every architectural decision, every deployment is public.
About Me
What drives me as an engineer — and a few things about me beyond the keyboard.
The tech stack I work with, the career path that got me here, and a glimpse of life outside the IDE.
How I built this site
kalandra.tech itself — built in public, with every architecture decision, deployment, and lesson learned written down as it happens. The site is the artifact.
Covers the webpage and its hosting, the API and its hosting, the database with event sourcing, the CI/CD pipeline with E2E tests. And more.
