Summary
👤
Senior🎓
Top SchoolWaldemar Sojka is a Principal Engineer based in Dublin with 14 years of experience building cloud-native data and backend systems using Java 17, Scala, Spring Boot, Kubernetes and both AWS and GCP platforms. He has progressed from QA and performance testing into hands-on engineering and platform design, repeatedly applying Apache Spark, EMR/DataProc and BigTable/HBase to large-scale data problems. At Dun & Bradstreet he blends DevOps and developer responsibilities—Terraform, Jenkins, Git and container orchestration—delivering resilient services that span S3, DynamoDB, Elasticsearch and serverless Lambdas. Comfortable across the full lifecycle, he pairs strong testing discipline (JBehave, JUnit, Mockito, Selenium) with production-grade deployment practices. A pragmatic technologist, he often brings testing-first thinking to system architecture, reducing risk while accelerating delivery.
