Senior🎓
Top SchoolPaweł Kołodziejczyk is a Senior Software Engineer with 11 years' experience building resilient, cloud-native backends and training teams in distributed systems. He specializes in Scala (now introducing Scala 3 and ZIO), Kafka-driven microservices, and Kubernetes, and has repeatedly combined hands-on engineering with internal knowledge sharing to raise team capability. As a former cloud architect and long-time technical trainer, he blends practical migration experience (12-factor approaches, DDD) with curriculum design that has trained hundreds of practitioners. He has a track record of optimizing prospecting and event-driven platforms for performance and scalability, and occasionally wears the technical recruiter hat to grow strong FP backend teams. Based in Queensland but rooted in Poland, he pairs an academic foundation from AGH with a pragmatic focus on observability and reliability in production systems.
