I started learning to program when I was 10 years old, and have had a passion for it ever since. As an adult, I've worked for a variety of companies developing robust and secure business applications and system-to-system interfaces for government agencies and financial services companies. I now work for a unicorn tech company as a Senior Machine Learning Engineer, having acquired my masters in Machine Learning and Natural Language Processing. Through my work experience, I have gained extensive application development expertise and specialized knowledge in network/socket programming, graphics and UI programming, web services programming, secure application design, data analysis, and machine learning.

I began as a self taught programmer, where I learned the art of debugging. When I finally made my way into school at the University of Utah, it didn't take much for me to refine the finer art of computer science methodologies. I have been working professionally now for over 7 years. Throughout that time I have contributed to many OSS projects including FubuMVC, Ripple, React-Bootstrap, Karma, and Selenium, I have also championed other OSS projects.

“Matei is great! Super patient for a non-technical person and provides very intuitive explanations for what is happening in code (e.g. server talking to client, client talking to stripe). Also is very adaptable to each person's needs (fast at referencing developer tools). Highly recommend!“

“Denys is a very patient mentor. His way of teaching is to help students thoroughly understand how something works step by step, rather than teaching only to solve a specific problem. This is my first time working with Denys, and I will continue learning with him in the future.“

Furthermore, the PDF summary provided at the end is an excellent review resource, as he specifically pointed out the fundamental gaps in my knowledge, which was great“
