What I'm looking for

I am looking for engineering roles leveraging Kotlin/Java and graph databases, with opportunities to build data-driven services, work across cloud infrastructure, and contribute to resilient, automated deployments in collaborative teams.

I am a senior-level software engineer with 4+ years of professional experience in Java and Kotlin, complemented by extensive hands-on work with Neo4j for graph analytics and data import pipelines. I have built and maintained microservices using Spring Boot, deployed with Docker, and worked across AWS and Azure environments.

My recent work includes contributing to interconnected projects for a major exchange, developing a RADAR analytics service and a network traffic permission tool, both leveraging Kotlin, Spring Boot, Vue.js, Cypher, Postgres, and infrastructure-as-code tools like Terraform and GitLab CI. I have also supported IoT cloud applications and handled backend responsibilities for transaction security systems.

I bring additional strengths in front-end development (Vue.js, JavaScript, TypeScript), SQL and NoSQL databases, DevOps basics including Kubernetes and Kustomize, and automation using Python and VBA from prior analytics roles. I communicate fluently in English and Polish and I seek engineering roles where I can apply graph data expertise and build resilient, data-driven services.
