At Eurasian Bank, I’m developing backend services for notifications and payments, including Kafka event processing and Camunda workflows. I’m preparing a new notification service for production to replace a legacy service; switching to push notifications reduced SMS usage by 80%.
At Netcracker Technology (NEC), I led the migration of backend services from Spring to Quarkus, reducing memory usage by 15% and improving startup times. I also redesigned the service configuration system, cutting configuration size by 50% and request overhead by 10–23% while maintaining backward compatibility with older production versions.
I designed, developed, and maintained B2B backend services at Netcracker Technology (NEC), taking responsibility for technical decisions, implementation, and production support. I built a mechanism for loading configuration from S3 at runtime and migrated a service from Hibernate to jOOQ.
Earlier at Netcracker Technology (NEC), I developed backend features and integrations for an enterprise B2B telecommunications platform. I also collaborated with senior engineers on features and service improvements, and gradually took on more responsibility for design, implementation, and production support.
