Guest Speaker - RevoU Masterclass Data Analytics

A fun and engaging session with students and aspiring analysts

One month ago, I had the privilege of being invited as a guest speaker for an event focused on SQL and data analytics. It was an incredible opportunity to connect with students and aspiring analysts—especially meaningful because I once sat in their place, trying to figure out what “real” data work looked like outside the classroom.

Session 1: SQL and Data Analytics

In the first session, we walked through the fundamentals of data and databases: what data means in the real world, how databases store and organize information, and why understanding this foundation matters for any data-related role.

Then we dove into SQL basics, starting with:

  • Simple SELECT statements
  • Filtering with WHERE
  • Sorting with ORDER BY
  • Basic aggregations using GROUP BY
  • Understanding how JOIN works and why it’s essential for combining data

Rather than focusing purely on syntax, it was aimed to explain the “why” behind each operation—why you would join tables, how filters help narrow down insights, and how grouped data can help summarize large datasets.

After that, we transitioned into some hands-on exercises, where participants could apply what they’d learned right away. It was great to see how engaged everyone was during the exercises and the thoughtful questions that followed. It was also surprising how well everyone was doing, much faster in learning than what I used to be 3 years ago!

Session 2: Alumni Sharing Session

Later in the day, I joined the Alumni Sharing Session, where I spoke about my journey into data analytics. I shared:

  • How I first got into data
  • What helped me the most when learning
  • The challenges I faced when transitioning into a data role
  • I also shared stories from real projects—especially how mistakes and messy data often teach us more than clean, perfect datasets ever could.

We also talked about career paths, job interviews, and how to keep learning in a field that evolves quickly. One point I emphasized was that you don’t need to be a “data expert” to get started. If you understand the fundamentals, stay curious, and keep practicing, you’ll eventually grow.

Final Thoughts

What I enjoyed most was the open Q&A and discussion that followed each session. It’s always encouraging to hear fresh perspectives and questions that challenge the way we think about data.

Speaking at this event reminded me how powerful it is to give back. Helping others gain confidence with data—even in small ways—feels deeply rewarding. I’m grateful to have been part of it.

Special thanks to RevoU and the team involved, I wouldn’t have been able to share what I have to others without their help. Thank you for inviting and giving me such an amazing opportunity, and I’ll always be ready to share any knowledge anytime.
