My First Post

Purpose of These Posts

Since this is my first post, I’d like to share how I want these posts and reports to be.
I want them to feel like a journal—somewhere I document my entire journey toward becoming a data engineer, which is my current goal.
So, I’ll be sharing everything I’m studying and learning along the way.

Portfolio Progress

Today, I was finishing up my portfolio.
I built it using:

Pure JavaScript
CSS
HTML
Node.js (on the backend)

I’ve also been diving into data structures because I believe they’re fundamental.
Even though I already have a solid grasp of programming, I realized there were still some core concepts I was missing.

Study Plan

That’s why I plan to start Harvard’s CS50 course soon to strengthen my foundations.
I’ll also complement that with Augusto Galego’s data structures course.

Learning Big O Notation

Right now, I’m learning about Big O Notation.
I’ve understood that it’s a way to measure an algorithm’s complexity—both in terms of execution time and memory usage.
Essentially, it helps you evaluate how well your code scales as input size increases.

O(n) O(n²)

Conclusion

And that’s it for now! Thanks for following along.
