What I'm looking for

I'm looking to take end-to-end technical ownership of critical backend components, building scalable, fault-tolerant, secure, high-load systems in fintech, banking, or cloud-native microservice environments.

I've built and launched SmartDeal's mortgage-selection MVP, then migrated it into Kubernetes-based microservices spanning bank-offer search, notifications, and a mobile client account. The product was later acquired by Cian.

Across Practice ofSuccess, Light-Service, Dom.RF Bank, and ITeco, I've delivered secure Java and Spring Boot services for fintech, payments, CRM, and banking platforms—optimizing PostgreSQL, implementing Redis caching and asynchronous messaging, and automating delivery with Docker, Kubernetes, Jenkins, AWS, and Yandex Cloud.
