Achievement Showcase
2020–2026, a fintech app inside TelegramAn API gateway for all our apps, 700 requests per second
Subscriptions through 8+ providers: App Store, Google Play, Stripe
A wallet on 9+ blockchains, with a receiver built on the outbox pattern
An AI assistant used by thousands of people
I joined as an intern and became a senior engineer three years later. Most of the time there were only two of us on the backend, so I got used to owning the whole system: from the database schema to night-time debugging when production got slow.

About
Pace
I work at a calm pace and look after my health: cycling, walks, enough sleep. I think products come out better this way than in crunch mode.
Languages
Russian is my native language. English B1, working toward B2. German A2.
