Gdynia, Pomorskie, Poland

Senior PHP backend and platform engineer with nearly 20 years of commercial experience. Currently Technical Lead at EASI'R, building microservice backends, event-driven integrations, and managing Kubernetes-based delivery for an automotive dealer CRM platform.

What I'm looking for

Looking for backend, integration, or platform-adjacent engineering roles where I can contribute across the full delivery stack — from PHP services and APIs to Kubernetes workloads and CI/CD automation. Prefer product-oriented teams, remote setup, and environments where code quality and operational reliability actually matter.

  • Developed a suite of integration microservices connecting the platform with external systems: lead intake and tracking for third-party partners, aftersales workflows, dealer vehicle configuration and stock, customer and vehicle data synchronization, and manufacturing and ordering tracking — event-driven via Kafka, AMQP, and Amazon SQS.
