Position: Senior Software Engineer | Tech Lead | Architect

English level: fluent
Years of experience: 11

One of my biggest achievements is creating multiple projects from scratch single-handedly which are now used by hundreds of millions of active users (parts of messaging systems at eBay Classifieds, electric car fleets management at Shell). 
Apart from that, I pushed through and worked on several initiatives which greatly helped companies to achieve more:
 - a generic Open Banking (PSD2) connection test which reduced developer work from 1-2 days to 10 minutes per bank connection
 - internal Cassandra monitoring tools
 - Google Cloud PubSub subscriptions autoscaler
 - various internal libraries that are written in Go, Kotlin, and Nim
I have been working as a Software Engineer since 2012 in 3 different countries (Ukraine, Poland, Netherlands). I was employed by leading companies (for example, eBay, Shell, ING), was a team leader, global architect, and a mentor for interns. Some of my working directions include financial systems, high-frequency trading, data warehouses, HA/HL (high availability / high load) applications, communication channels, and cloud solutions serving hundreds of millions of people around the world.

My major is backend development using Go, Kotlin, and Java. Apart from that I’m usually involved in the design and development of applications written in Python as well as building infrastructure with the HashiCorp stack. I also fancy Nim programming language which is great, although it didn’t get a huge outreach so far.
I'm looking for full or part-time, fully remote employment. Any projects of any complexity are very welcome.
I don't support and don't work on projects representing products that I believe to be harmful to society (for example, alcohol, drugs, gambling).
