    Backend developer of digital mobile operator izi. Currently using tech. stack: Java 8-17, Spring (Boot, API Gateway, WebFlux, Data JPA), Hibernate, ProjectReactor, Quarkus, Mutiny, Flyway and Mongock migrations, PostgreSql, MongoDB, Rabbit MQ, Kafka- Developing new, maintaining and refactoring existing microservices, bugfixing, creating new features according to business requirements. Also participating in moving functionality from the core modular monolith into separate microservices according to business domains. E.g. I've refactored content service based on Quarkus framework with reactive stack (RestEasy, Mutiny) and Mongo database (ripped of all blocking instructions and upgraded library version to the latest) which results in increasing stability from 98.7% to 99.5% according to load tests. - I've created a new push notification service using the Firebase Admin SDK as a replacement for the legacy FCM API and added a push token validation mechanism, which reduced the number of 'dead' tokens. Altogether, this led to a threefold decrease in the time required for broadcasting push notifications- Mentoring and onboarding new colleagues, code review.
