About

Who am I?
I’m a backend developer who’s been writing Java for decades and Kotlin for years — long enough to appreciate the tradeoffs and long enough to have some strong opinions.

I created this blog to share practical insights about building reliable backend systems using Kotlin, Spring Boot, Reactor, and other tools I work with daily. This isn’t a beginner’s tutorial site — it’s a collection of patterns, experiments, and lessons that actually matter in production.

I publish under the name Red Mug Guy. It keeps the focus on the ideas, not the credentials — though if you’re wondering, I’ve spent most of my career in tech, leading backend projects, mentoring engineers, and sweating the details that most people don’t see until things go sideways.

Why the red mug?
It’s on my desk. Every day. Usually filled with something caffeinated.

Thanks for stopping by. If something resonates (or breaks), feel free to reach out or leave a comment — when I open up feedback, I’ll post a way to get in touch.
