How I’m Building My Data Science Portfolio From Scratch

The Beginning of the Journey

Hi! I’m Alejandro, a physicist with a deep passion for data-driven problems. After years in academia, I’ve decided to pivot into Data Science — and I’m building my portfolio one real-world project at a time.

What I’m Doing

I’m not just following tutorials — I’m building practical projects that reflect industry-relevant challenges, such as:

• 📊 Sentiment Analysis — currently in progress!
• 🤖 Object Detection
• 🧠 Recommendation Engines
• 📦 ML Pipelines & MLOps

Why Build in Public?

I want to be transparent with my journey. This blog (and my website) will be the place where I showcase not only the results, but also the learning process. That way, employers and collaborators can follow along and see my evolution. a
