"Lukas is a top notch teacher you’d find. I found his materials and approaches to a topic very helpful."

"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."

"Lukas Halim is intelligent, hardworking, empathetic, and intentional. I would trust him with any commitment he decided to undertake."

"Lukas is a highly skilled professional and passionate about his work. I enjoyed collaborating with him . "

"I have known Lukas since 2005 and we worked on one of the projects. Lukas is technically very sound IT professional and I highly recommend him for what he does. "

"Lukas Halim's Tableau course served as my initial introduction to the software when I decided to shift my career from software testing to a Tableau developer role. Despite having an accountancy background and no prior formal education in technology, I sought out high-demand tech jobs after moving to the USA. I eventually found a position in functional testing with a leading bank in 2006. After seven years in that role, the desire for a technology-focused career led me to Tableau after seeing some impressive, visually-rich reports during a meeting. I discovered Lukas Halim's course on Udemy around 2015 and enrolled, believing it would fully prepare me for a job transition. While I initially felt ready, I realized during a subsequent interview that the course was foundational and only covered the basics. However, it was a valuable starting point that prepared me to seek out more advanced courses later on, which ultimately gave me the confidence needed to pursue my career goals."
