Summary

The company I worked for first was mainly focused on bussiness integrations with government systems. I took part in developing a system for alcohol virtual movement registration for one of Russia's biggest supermarket chain (X5). The system was what people call "legacy" and was not really well documented, so it would take a lot of learning and code reading before I could actually get to the task. Also, the most legacy part about that project was that I and my collegues had to "divide" one big system written with the usage of EJB3 into various microservices using Spring-Boot + OracleDB.

My second and third (current) companies are mainly focused on working directly on government systems and services. The set of projects I and my collegues have been working on for the past 2 years are responsible for Moscow architechure documentation storage and processing. When something is built in Moscow, there's a lot of documents that go with that, before, at the time, and after the building is finished. So we work on microservices that help organize the document processing and storage. That includes a lot of work with Spring-Boot for backend document processing operations, BPMN Activity for organizing the bussiness process, PostgreSQL for storing documents, events, and other information. Currently I am one of the "oldest" employees in my team, so there's also a lot of communications and mentoring involved.

I wouldn't say I have a lot of experience with cryptocurrency so far, I have just started getting into the topic lately, but I have always wished to try myself at international work as my whole previous experience has always been at purely Russian domestic companies. I want to do something about that, and I am fully willing to enhance my cryptocurrency knowlege and get deeper into the world.
