I've always been fascinated by how data moves across the world at the speed of light. It's not magic! The internet relies on open standards and precise addressing. I wanted to refresh my knowledge of networking fundamentals and the TCP/IP suite of protocols, so I went through a few resources and later made this post from my notes, covering common protocols (IP, TCP, UDP, DNS, BGP, NAT, DHCP, IPSec) and explaining how everything fits together.

I recently took a deep dive into the Linux kernel to understand how it handles processes, scheduling, memory, and more. While I had some OS knowledge from school, it always felt too abstract - so I wanted to see how things actually work. This post covers what I learned, from system calls to interrupts, and how kernel development differs from userspace.

Modern applications are often complex, distributed systems. Debugging them is not fun: you have to follow requests across services, logs get lost, and metrics are often hard to correlate. It's like looking for a needle in a haystack - except the haystack is on fire, and the needle keeps moving. This is where OpenTelemetry (OTel) can help.

I had a great time on The Cillers Podcast chatting about my journey in tech and hackathons! We talked about organizing hackathons at GitHub, how they foster creativity and collaboration, and their role in inspiring new product ideas. We also touched on boosting development speed with great tools and managing technical debt. Big thanks to the Cillers team for having me!

After more than a decade of writing software, I've read lots of opinions on how to write good software. Everyone loves to throw around rules and principles, so I'll do it too.
