Jeffrey is the tutor you want

Jeffrey is an extremely knowledgeable and compassionate tutor. I had 2 sessions with him and can say with confidence I trust his judgement and guidance. I hired him to help me study for several IT certifications because I am a recent college grad with degree in computer network and cyber security; but I have "NO" work experience. Jeffrey is guiding me with the best approach to obtaining certifications. In addition, he shared knowledge of a non-profit organization called Civil Air Patrol (CAP). It's an auxiliary of the Air Force but a volunteer service; I could work on cool cyber projects and take part in their IT programs to help gain meaningful experience. This has given me strength and I am very thankful.

Amazing Tutor for Data Structures & Algorithms!

had a great session with my tutor where we went over different sorting algorithms in Data Structures and Algorithms. He explained the concepts clearly and broke down the logic behind each sort—like bubble sort, merge sort, quicksort, and more—in a way that was easy to understand. What I appreciated most was how patient and thorough he was, making sure I grasped both the theory and the practical implementation. You can tell he really knows his stuff and genuinely cares about helping his students learn. Highly recommend if you're struggling with DSA or want to strengthen your foundations!

very knowledgable, and quick to adjust to the lesson needs

I had a use case with a cloud provider I had not used before. Jeffrey quickly determined how we needed to proceed to solve the issue I was having with clear understanding and methods to work through how I needed to continue and what I needed to learn to be competent.

Henry, 1 lesson with Jeffrey

I would compare Jeffrey to Ferdinand Porsche, He is the absolute best!

We went over interview questions for Cybersecurity interview, and he explained difficult concepts in simple terms. Would recommend to anyone! I told him-he needs to start his own school. If I had all the money in the world, I would listen to him every day for an hour just to be on top in the IT field. He is very on top of it! As Jeffrey told me to be amazing you always need to be working on it like you have a fun car project to work on every day to come home and get excited. If I could always have him by my side while working on it I would! Since Jeffrey kept on bringing up the car example to me this is what I would refer him as:) "I couldn't find the sports car of my dreams, so I built it myself"-Ferdinand Porsche with this quote I would describe Jeffrey! Thank you so so much Jeffrey for all of your help! Wish we could do it for longer!
