About Me

I'm a result-focused professional with 10+ years in IT industry. My role could be different depending on the current project stage and needs of a team. I'd been working on research projects for 5 years in applied science in data analysis. After that, I started working on projects with international and all-Russian big brands. We developed and implemented a lot of digital marketing and interactive media products. Also, I have an experience as a data scientist in user behavior research for online mobile products.

I carry out research on stock market and real estate. Passionate about researching how to improve performance. You can see my projects below.
