# Welcome

I'm **Emmanuel Konan**, a Software & Security Engineer with a focus on **applied cryptography, Public Key Infrastructure (PKI), and secrets management**. I like problems that sit at the intersection of solid theory and real deployment — where you have to understand the math *and* ship something that runs in production.

This site is my public working notebook: field notes, deep dives, and hands-on demos. Everything here is built around one habit — taking a concept apart until I can explain it simply, then writing it down. It doubles as evidence of how I think and communicate.
