I've worked on a solution for carshare company. Carshare’s users can book a car wherever they are,  using WEB/iOS/Android applications.
I’ve worked on major features, such as Payment System integration, ERP (Odoo) integration, Grafana setup. 
I’ve used Timescale DB for saving metrics. TimescaleDB is an awesome DB for time-series data.
I can insert data faster to TimescaleDB than to Postgres. TimescaleDB supports all Postgres functionality, such as dump, restore, join and geo.
Also I’ve moved some business critical properties to DynamoDB. 

My main responsibilities on the projects included: code review, requirement definition, performance improvements, designing, implementing and maintaining Java applications, supporting continuous improvement by investigating alternatives and technologies.
I'm looking for interesting project and challenging tasks. I want to try myself in big data or blockchain. Considering to switch to Golang. Office in Lviv or Kyiv is a big plus. Ongoing projects are preferred over startups and legacy
