Welcome to A Coder’s Musings
I am Vivekanand, a software engineer with over a decade of programming experience, I’ve worked across a range of languages—starting with Java and Go, dabbling in C, and now delving into the raw power of pure arm64 and amd64 assembly. Like many, I’ve faced intimidating bugs and performance puzzles that seemed unsolvable at first glance. But thanks to the generous global programming community and the wealth of online resources, I’ve always managed to find a path forward. That spirit of sharing and support is now inspiring me to give back by documenting what I’ve learned.
