Who Am I?
Hello! I'm Alex, a software engineer based in Teresina, Piauí, Brazil. My passion lies in understanding how things actually work, from electron flow in low-level hardware to complex web systems and AI-driven solutions.
I believe that technical knowledge doesn't have to be boring or superficial. This blog (Bit a Bit) was born out of my desire to document my research and explain complex technical concepts in a simple, straightforward way — "uncomplicating technology, bit by bit".
