Dmitrii Frolov

I started writing Java at the age of 14, driven by a passion for game development: creating games, building marketplaces, and experimenting with everything that could be brought to life through code. Curiosity quickly turned into a profession — by 17, I was already working as a Java developer at T-Bank, building reliable fintech systems.

Today, I am a Tech Lead and Architecture Owner of the Segments team. We are responsible for debt collection across seven of the bank’s key credit products — meaning the stability of our solutions directly impacts the business. In addition, I am part of the Architecture Committee and the Collection Reliability team, where we focus on scalability, engineering evolution, and the resilience of the entire ecosystem.
