Summary
Jozef Zaťko is a Java Tech Lead with 11 years of experience building cloud-native, highly available backend systems from design through production. Based in Bratislava, he specializes in Spring Boot services, Kubernetes deployments, and observability—having led initiatives to introduce Prometheus, Grafana, Sentry and a dedicated Monitoring and Alerting Platform. He has driven technical roadmaps and Java chapter goals while reducing technical debt across Nordic fintech and international lending platforms. Comfortable owning the full lifecycle, he blends hands-on coding with team leadership, code review discipline, and CI/CD and Helm-based deployment practices. Notably, he pairs traditional JavaEE experience (document generation and JasperReports) with modern microservices and distributed messaging (Kafka, RabbitMQ) expertise. His background in software engineering and a track record of operationalizing monitoring make him adept at keeping complex systems both evolving and reliable.
