“I had an amazing experience learning Power BI with Rafael as my mentor. He is superb—extremely knowledgeable, clear in his teaching, very professional, and genuinely passionate about helping others learn. He took the time to explain every concept in detail and ensured I was confident before moving forward. I highly recommend Rafael to anyone looking to upskill in Power BI. ⭐⭐⭐⭐⭐ He solved my doubt, so genuinely and professionally. I am his fan, not only for the Power Bi, but also for his personality. Note:- Its an AI written review but 100% genuine review from Chetan Gupta (India). Lots of Love, Thank you. You made my day“

“Lucas did an amazing job helping me with my problem. I got completely turned around debugging the issue for two days and I thought I tried everything. In the end, we tried the same everything, but more calmly, and there it was, problem identified. I can now move on to fixing it. But in the meantime, I also want to mention that it was great pleasure chatting with Lucas. His English is perfect, his technical knowledge is broad, his manner is pleasant, and he didn't talk down to me. I almost hope I'll have another problem to ask him about...“

“I had a fantastic session with Erum focused on understanding the internals of the Spark UI. She explained complex concepts like stages, tasks, and shuffles in a very clear and visual manner. What really stood out was how she connected the theory with real Spark execution graphs and showed me how to interpret performance metrics effectively. Erum also guided me through practical optimization techniques—like how to reduce shuffle overhead, how Spark breaks jobs into stages, and how to use partitioning intelligently. Highly recommended for anyone needing deep, hands-on Spark guidance“

“Ryan was so quick to respond, very helpful and friendly. We were given many options to improve what we already had and then Ryan guided us through the best options for our timeline. The work together was a combination of tasks I could execute on my own time, and direct edits through the code window that we could insert immediately. 100% satisfied!!!“
