The Good, the Bad, and the Ugly of Working as a Software Engineer at AWS

After 5 incredible years at AWS, I have recently decided to join Zscaler.

As someone who's dabbled in everything from Aurora DB to 5G, VPC, Gen AI security, and even filed a few patents (no big deal), I’ve seen it all: the good, the bad, and yes, the downright ugly. But don’t worry—there’s plenty of fun to be had along the way.

For this post, I'm using Raspberry Pi 3 with Raspbian 9.3 with Kernel 4.9
