Personalized Artificial Intelligence Lessons: Machine Learning, Deep Learning, Computer Vision and much more. Computer Engineer. Theory and practice. Immediate availability.

Honestly, Andrei's one of the best coding instructors I've had. The guy actually knows his stuff and explains things in a way that makes sense, even when you're completely lost. His lessons are pretty well put together - not boring like some other courses I've tried.

Here a very professional teacher, the god of Java come to him to not have any questions about IT subjects.

Andrei was super helpful in teaching me R which was a new programming language for me.

I’ve had the pleasure of working closely with Andrew on our startup, Tic Drive a platform for booking car services through workshops. As one of just four team members, he played a central role in building the entire backend, managing the database, and contributing to the frontend alongside me.

Beyond his strong technical skills, what truly stands out is his ability to explain complex concepts clearly and patiently something I’ve experienced firsthand while collaborating on our mobile app (now live on the App Store) and website. He’s not only a talented and reliable developer but also a natural teacher. I’m confident any student would benefit from his guidance.

I had a chance to take a couple of classes with him and the doubts I had he took them all away, a really really knowledgeable prof and very passionate about his work and the IT world, plus we have stayed on good friendly terms and besides programming we also talk about other things, he is a really interesting person.

Andrei has been my teacher for a couple of months now, and I’m absolutely thrilled. He’s helping me build a project in Python while also giving me a solid foundation to understand the language itself. He’s incredibly knowledgeable, extremely polite, punctual, and always willing to help. I believe I have very high standards, but he has gone far beyond my expectations. He’s been incredibly helpful!

Andrei is a very kind and competent teacher. He understands my difficulties with patience and explains complex concepts in simple and clear ways. I absolutely recommend him to anyone who needs serious and effective support in Computer Programming!

I have had lessons with Andrei more than once on C++ programming, functions, arrays... and he has been a huge help!

Andrei is very good at explaining in general, understanding the student's gaps and solving them. He has a lot of experience in the field and in my project at university he helped me a lot! He managed to be very efficient in terms of understanding and timing.

I am a student taking a C# class at the University of Nevada Reno. I have been struggling with certain programming concepts. Andrei has been tutoring me for the last few weeks and he is an EXCELLENT instructor! He has an expert understanding of the program, he is patient, and he explains concepts very well. I fully recommend that other students needing additional help learning C# contact Andrei.

I had a great experience studying JavaScript with Andrei, he’s very clever, aware of what I needed, he just evaluates your status and makes you understand everything that seems impossible. I strongly recommend him, for me it was a great and worthy experience.

Andrei is a great teacher and an expert in programming languages. He is serious and responsible. I found his method very good.

I've been studying with Andrei for 3-4 months already and I recommend him because up to now he has clarified every doubt I had, he is helping me really a lot with javascript and is able to deal with every problem

Andrei helped me learning the Python language for an exam at University. He is very prepared on the subject and also extremely helpful and kind! I recommend him to everyone!

My family hired Andrei to fix problems i had in Mathematics (9th grade, 15yo).
We mainly worked (approximately 3 weeks) on polynomials and equations, also going through everything previously encountered during the year.
His ability to explain such difficult things (from my point of wiew, someone could obviously find it easy) is unmatched, compared to my former teachers; this is either bad luck with them or i was just really lucky with Andrei (more likely).
His charisma and his positive attitude makes it easier (he's also a really funny guy) , also considering the fact that he's absolutely prepared on everything i needed (or one could need).
Everything was honestly flawless, and my marks went from an E- to a B+, stuff i honestly wasn't expecting.
Overall, Andrei cleared 100% of my gaps in maths.
Would totally recommend, he crushed my expectations.

Andrei is exceptionally skilled. He taught me programming and tailored a personalized course for me. Definitely recommended!
