After graduating from Moscow State University I started my career as a researcher and a software engineer in a small company. This helped broadening my practical knowledge and acquiring new skills ranging from database management, C++ and C# programming, and Python to image and image sequence analysis, computational optimisation, GPGPU and deep learning. During these years I participated in a number of international projects which included writing proposals, designing and developing proof of concepts and presenting them to customers in the UK and Singapore.In 2021 I joined Yandex - one of the biggest IT companies in Eastern Europe - to help developing ML-based microservices for ride hailing efficiency. Here, I improved my ML skills — decision trees and time series forecasting, specifically — and gained experience in A/B testing, uplift modelling, microservice architecture, big (very big indeed) data analysis, MapReduce programming.Also, I am a co-founder of a Bulgarian SME which provides R&D services to other companies. It can be seen as a side project which I participate in my spare time to solve problems other than my primary job can offer and to broaden my scope of knowledge (new methods and new domains) and extend list of technologies I can use.
