Working as a software engineer on various projects, which focus mostly on finances, banking and social

Achievement Highlights:
* Was part of a team that is in charge of developing soft real-time data transfer and management
system which included: MQTT protocol integration for stock exchange quotes, a fully functional chat
system, data management and integrations with MetaTrader 4, social components and social data
management via soft real-time flow. It was an endeavor focused mostly on implementing a
microservice architecture, together with new technologies which are on the rise, like Scala, Go, Erlang,
RealTime Protocols (MQTT, FIX) and database systems, which include: PostgreSQL, Cassandra,
ElasticSearch. Mostly our focus is to deliver the most reliable solution for forex trading. With the

ECR20 token NGC, and support for all major crypto currencies and tokens. The ICO raised over 45 mil $
in 15 days, starting from 1st December 2017.
* Developed a fully functional system for soft real-time data flow ( chat, notifications, generic data
routing ) using XMPP and HBase for Swipestox. Tech stack was Java, HBase, PostgreSQL, Swift with
later support for Firebase. The system was discontinued in favor of the previously mentioned MQTT
implementation which focused more on mobile client overhead and resource consumption.
* Developed a huge part of the NAGA exchange ( ), focused mostly on microservice
architecture. The tech stack included: Go, Scala, PostgreSQL, Erlang
