At JiTTeam, I develop and maintain Kotlin microservices for advertising products used by sellers on a leading Polish e-commerce platform. I work on domain logic and asynchronous processing in a DDD and event-driven architecture.
I analyse production behaviour and troubleshoot incidents using Grafana, MongoDB and BigQuery. I also write automated tests and participate in code reviews, refinements and production deployments.
At Software Mind, I developed Java and Spring Boot microservices for SMS and MMS delivery for international telecommunications operators. I also contributed to modernizing a service-provisioning platform and maintained data integration and replication mechanisms using Debezium.
Earlier at Software Mind, I designed and deployed a monitoring environment for geographically distributed, SIM-enabled field devices, automating its deployment and configuration with Ansible. My computer science studies also included an AWS-based observability platform and a comparative analysis of concurrent task execution models on the Java platform.
