Built to answer a simple question, How do you operate hundreds of embedded devices without ever touching them?

I don't have a favorite stack. I have a favorite question, How does this actually work?
That question has shaped almost everything I build. Whether I'm working with cloud-native systems, networking, operating systems, backend services, or hardware, I'm drawn to understanding what's happening beneath the abstraction. I enjoy building systems not just for the end result, but because it's the most rewarding way to explore how computers really work.

I primarily write C/C++, Go, and JavaScript/TypeScript, while also having hands-on experience with Java and Python.
My work focuses on cloud-native systems and network security, with an emphasis on building reliable and secure infrastructure. I rely on technologies like Docker, Kubernetes, PostgreSQL, Redis, Kafka, Git, and Linux to design, build, and operate those systems, choosing the right tool for the problem rather than the other way around.

RSSA simple breakdown of how different layers detect, propagate, and react to events from DB triggers and outbox events to Kafka, webhooks, and eBPF/XDP.
Understanding one repository fingerprint led me through GPG, Release files, hashes, and the cryptography behind every apt install.
