Oleg started his employment with ObjectStyle back in 2013. At first, he was mostly working on the Apache Cayenne project. He then became a software engineer on one of the client’s projects here at ObjectStyle. The team was implementing DevOps best practices to improve time-to-market and software quality for the client. Practices like code reviews and unit tests were a norm. Over time, Oleg became the team lead on that project. He was responsible for making decisions regarding the apps’ architecture, choosing technologies, and performing code reviews. On the managerial side, Oleg synced up with customer on the daily basis, turning customer ideas to technical tasks and distributing work between team members. Since he had started as the lead, the team introduced elements of the Kanban framework to its work routine to increase transparency and improve efficiency.

In 2022, Oleg was promoted to Engineering Manager on a tech-heavy startup project where he now heads a team of engineers. He performs some managerial duties, but mostly oversees the technical implementation by reviewing other programmer’s work and making technology stack choices.

Oleg holds a degree in Economic Cybernetics from Belarusian State University in Minsk.
