I'm learning offensive security full time, and writing down what I get wrong on the way.

Working through Linux, networking, Active Directory and web application security. Experience building sites before this, which turns out to be a useful place to start from.

Understanding how things break, not just how they work.

I focused on understanding how things work, not just making them function. Now I focus on how to break those things. Web Development did come in handy.

HTML & CSS

Where it all began. I challenged myself to build a Tesla homepage clone using only HTML and CSS, deliberately avoiding JavaScript to force myself to master the fundamentals first. It taught me that working within constraints breeds creativity, and that you can achieve more with pure CSS than most people realise.

JavaScript

This is where everything clicked. I went from static pages to building interactive applications, learning DOM manipulation, event handling, async/await, and how to actually think like a programmer. Every bug I solved made the next one easier. Projects like my to-do list and login system pushed me to understand not just what code does, but why it works.

Node.js

Taking the leap to backend development. Building REST APIs, handling user authentication, connecting to databases, and finally understanding what happens on the other side of a fetch request. It changed how I think about web development as a whole.

Offensive Security

Where I am now. Six months in Medellín studying full time: Linux and networking fundamentals, Active Directory, web application vulnerabilities, and working towards CPTS. Building sites taught me how applications are put together. This is learning how they come apart. Everything I work through gets written up under Writeups.
