Early in my career 20 years ago I built database applications without fully grasping their inner mechanics. Facing performance issues, racing conditions bug and even corruption often left me helpless.

I resolved to truly understand the workings of database systems, ensuring I knew every query from my app and its execution in the db and what I choose to make as a transaction and what I make into an atomic query.

From that day I have fascinated by pursuing deep understanding of what is happening behind the scenes in software. If you follow me here you would see deep dive posts about backend, databases and operating systems.
