"I would like to endorse Lukas Halim for his outstanding contributions to the field of IT and analytics.

I began my IT career in 2017, where I had the opportunity to work on Tableau projects. At the time, I had little knowledge of analytics. While searching for resources on platforms like YouTube and Udemy, I discovered Lukas Halim's videos. After watching just a few, I quickly connected the dots and applied what I learned to my projects.

Due to the success of my work, I was encouraged to pursue Tableau certifications. Once again, it was Lukas's courses—both paid and free—that played a crucial role in helping me achieve 2-3 certifications during that period. Although Tableau has evolved significantly since 2017, I still refer back to Lukas's courses whenever I need a quick refresher. His teaching has been instrumental in my growth in analytics."
