ABOUT ME
Experienced developer with over 10 years of teaching, freelancing and research experience.
Experienced developer with over 10 years of teaching, freelancing and research experience.
I am first and foremost a teacher, holding a high school position ever since I was doing my masters over 5 years ago. Right now I teach various introductory courses and tutorials at the university level, covering languages and concepts such as Python, Java, algorithms and data structures, C#, machine learning and web development using Angular, React, Firebase and various backend technologies.
I have a PhD in machine learning and my philosophy is "if I can't explain it well enough for most people to understand it, I need to go back and understand it better myself before trying again".

A lot of machine learning experience, mostly gained during my 3 PhD years. Mostly ran experiments and finetuned algorithms to provide better results on our data sets. I worked with data from various fields and used algorithms raging from genetic algorithms, to linear and logistic regression, to SVMs, to most neural networks and also decision trees and random forests.
I also did freelancing and industry work using machine learning, where I used tensorflow intensively, mostly in computer vision applications.

Used Python 3 intensively in my teaching and research career. Our first year university students work a lot in Python. For some of them, it's their first contact with a programming language, so as an educator, I must have a strong grasp of the language in order to properly teach them.
Also used Python 3 for most of my machine learning work.

I highly recommend working with Vlad. He is professional and highly skilled. Once again, he answered all my questions and explained anything I asked very clearly. He is also very considerate of time, which I appreciated. He works efficiently and ensured we made effective use of the time throughout the session. He's an excellent mentor and returning for another session with him was very helpful and enlightening.

Vlad is an excellent mentor. He asked in advance for the files and came to the session prepared. He was knowledgeable and professional. As well as providing detailed help, he listened and answered any questions. I was very happy to have the issues resolved by the end of the session.
