    Python for Data Science Bootcamp

    I genuinely learned so much in this class that is immediately usable.

  • Hannah Hill Jul 15, 2026
    Python for Data Science Bootcamp

    Art, our instructor, provided many applied examples of how to use the knowledge, and he made sure we were practicing the problem-solving skills we'd need to be able to find and use Python's built-in aids to debug code independently. He welcomed questions and providing assistance to students one-on-one, while somehow focusing on the insights from that interaction that showed key take-aways applicable to the entire class.

    10/10! Garfield is fantastic! He brought a group of strangers together to complete a hard task and made it fun. Even online, I felt connected to my classmates as we worked together to learn a new skill. The materials are so effective for learning that it baffles me that it took me so long to learn SGL before coming to this class. I feel like I have needed glasses my whole life and finally got them!

    SQL Bootcamp

    Great introduction to Noble Desktop, as this was the first class within my course package.

  • Adrian Houston Apr 25, 2026
    SQL Bootcamp

    I took this course in person just for fun while visiting NY — not planning a pivot to data science, just curious — and it was exactly what you'd hope for when learning a new programming language. The instructor, Garfield, was the best: a great mixture of storytelling, leading questions about the logic behind SQL, and his own humor to keep students engaged throughout the entire bootcamp. The content was easy to follow and well organized, and even though three consecutive days of six-hour coding sessions sound like a nightmare in theory, the practical applications and Garfield's calculated and humorous approach made it a delight.

  • Keith Williams Mar 18, 2026
    Python for Data Science Bootcamp

    This is a very good choice if data science is your goal. I will take the SQL course next.

  • I really appreciated just how up-to-date the material is. The instructor, Brian, was great. I loved his instruction methods.

  • Daniel DaSilva Mar 8, 2026
    SQL Bootcamp

    10/10 experience with Noble Desktop! The materials provided were excellent, and the instructor was top-notch. Garfield was an excellent instructor. He talked slowly, gave lots of analogies to help us absorb the content better, used humor, and was very patient with us all. I would absolutely take a class with him again. The class had a good pace and no pressure self-exercises. Extremely helpful to have the Zoom recordings so I can go back and watch as I practice.

  • Class content and materials were fantastic. I learned a lot more than I expected. The instructor is great -- he knows this stuff inside and out.

  • Crystal J. Mar 2, 2026
    Python for Automation

    Art knows the material very well, and he is super helpful in keeping us caught up and answering questions. I like that he does impromptu tests of our knowledge. I don't always get it right, but the quick checks help.

  • Crystal J. Mar 1, 2026
    Python Machine Learning Advanced

    I love Brian's teaching approach -- he explains the material in detail, and gives us adequate time to try things for ourselves. I LOVE that he teaches the outline of the material, but also improvises and shows more of what can be done. The materials were fantastic. Loved using VS Code. I hadn't used it before, but I like it way better than Google Collab. The VS Code environment is so much more stable.

  • Christopher O. Feb 8, 2026

    Garfield has been a solid instructor for all four of the data science bootcamps I have attended. He is a master of the material and is effective at conveying concepts and theories with an appropriate amount of humor and anecdotes to keep things interesting. The pace of the bootcamp is fast but that was anticipated. We were introduced to all the major concepts of the topics, and I'm enjoying learning further outside the classroom.

  • Julio O. Oct 22, 2025
    SQL Bootcamp

    I liked the fact that the class is hands-on, and the presentations cover the important concepts very well.

  • Kash was a great instructor, and I certainly learned a lot. Thanks!

  • Take this course if you are interested in learning best practices and principles for safely incorporating AI APIs into your full-stack web applications. Intermediate experience with Python, JavaScript, HTML, and CSS is advisable. I had Brian, the creator of the course, as my instructor. He's passionate about this technology, and you will benefit from his professionalism and real-world experience in this space. At the end of the course, you will know how to augment web applications with AI technology, and you will have two apps and a detailed 141-page reference document to refer back to.
