About

I am a software engineer. I have been working in the IT industry for more than 10 years. The bulk of the projects that I involved in were heavy enterprise applications with strongly connected business entities and complex business logic, as a rule, having a high load, and a huge number of users.
I have an economist education, but after half a year of practice as an economist, at the dawn of my career, developing macros on VBA, I’ve realized that the description of logic and the management of complex processes and data structures are much closer to me. And so my career as a programmer began.

What I do
I manage processes of development and delivery of new features, select technologies for new solutions, monitor the application codebase, do code reviews and release management, develop software architecture, by the way: I really like microservices, orchestrating and all related to high load infrastructures. Usually, I create infrastructure for new projects or change it to a more progressive one for old ones.
I’m actively involved in backlog formation and the distribution of tasks between employees.
And I also write code. Whatever global tasks confront me, I never deny myself the pleasure of taking a task to develop.
