At Bereke Bank, I designed and shipped a credit-card microservice from scratch to production in six months as the sole backend engineer. Since launch, it has issued over 10,000 cards, and I integrated it with seven internal and external systems.

At Sberbank, I developed a high-load brokerage platform and a document-upload microservice that reduced request processing time under load by 7%. Earlier, I worked on banking microservices at Home Credit Bank and an e-commerce platform for a bank and its partners at ASPIRITY.
