About

📩 [email protected] 5 years ago, I was working as a Lab Analyst. I didn't have a Computer Science degree. I didn't have a "tech background." I just had a curiosity for Data and a willingness to learn. That curiosity took me on a wild journey from self-teaching SQL in the evenings to working as a Data Engineer for world-class companies like Amazon 📦 and Nestlé 🍫. Now, I share everything I learned along the way so you don't have to guess. I post daily about: ➤ Data Engineering & AI: Real-world skills, not just theory. ➤ Career Growth: How to break into Data and climb the ladder. ➤ Motivation & Habits: The actions you take daily determine your success.

      After 1 year, I got promoted to Data Engineer ll. I’m so grateful to Inditex for giving me this promotion! The duties were very similar, although in the last role I was doing more mentoring to some junior engineers. I'm sure that they are shining now!

      This was my first job as Data Engineer. Wow! I’m no longer an analyst but an Engineer. It felt so cool! I’m so grateful to Inditex who gave me the chance to work as Data Engineer l. I was in the Master Data team and my colleagues were awesome. With Snowflake as cloud data warehouse, my team and I were maintaining more than 150 data entities which where built using Kimball data modelling best practices.
