Viktor B.

Mathematician Programmer and Lecturer, Computer Science PhD

Hello! As a holder of a PhD and a Master's degree in Computer Science and Math, I like to tackle non-standard problems in Optimization, Operational Research, Mathematical Modeling, Computational Methods, and Algorithms. I like to deliver solutions from formulation through production-ready code, document the solutions, and tweak them for further improvement. As an experienced developer in C, C++, and Python, and also a teacher of Programming and Mathematical courses, I would like to help you in these fields. So full-stack engineering problems, like: - Research , - Scientific Writing, - Coding, - Documentation, - Manual creation, - Tutoring, - Lecturing, - Mathematical and Statistical Analysis are the things I'm eager to do. I have no fear of dealing with new programming languages or frameworks, and basic knowledge of C/C, MATLAB, Golang, Java, SML, etc., allows me to switch between the tools if it's required for the task.
