At netPrint, I designed and implemented backend components for a high-load microservices platform using Java, Kotlin, Spring Boot, and PostgreSQL. I integrated payment services for a leading Eastern European bank, increasing successful transactions by over 10%.
I also led the backend architecture design for a customer bonus and promotion system, applying DDD principles and Apache Kafka to reduce campaign time-to-market by 40%. I contributed to decisions on service boundaries, data flows, and fault tolerance.
At 42, I developed and maintained backend services for EMIAS, a large healthcare platform. I implemented Kafka message streams and Prometheus monitoring, and refactored legacy modules to reduce response time by up to 50% under high concurrent load.
Earlier, at GMCS, I improved report generation performance threefold and implemented a workflow management module deployed to Microsoft Azure. I currently develop personal and freelance software projects with Java, Kotlin, Spring Boot, and PostgreSQL, managing them from design through deployment.
