Developing services for Sports Betting platform using Erlang/OTP.
Working with hot code swapping, erlang distribution, and rabbit MQ as a transport. Some services in python.
Enable future scaling platform using elixir, Kafka as transport and split components which should be able to consume millions of requests as soon as possible and store to Kafka topic, from which other components would take data and store to DB in a more lazy way.
Nowadays working on crypto trading platforms with high-realtime requirements.
Help businesses get rid scaling issues and limitations in the software.
Working on helpful social projects.
Projects with high technology requirements.
So as my favorite language is erlang, I would like to work with erlang.

knowledge of Erlang as functional language and comprised profound use of Erlang’s OTP libraries
and design principles, interaction with relational and non-relational databases, implementing and
testing of certain mathematical models related to finances and risk-management. Development and
support of CRM system with BPMN processes was based on the use of Erlang and its OTP
libraries, and partially Elixir, use of non-relational Rocks-DB, installing/porting of the system to
different platforms (Linux, MacOS, and Windows, that required, in particular, certain
study/knowledge of cmake syntax). Also, the latest project required certain work with/on javascript
libraries related to cryptography (PKI and use of digital signatures) and use of different
cryptographic transformations. Both development of betting servers’ backends and CRM system
comprised testing of the whole chain of ‘server-client’ processes by means of browsers’
Development Tools.
