About Tomasz
Java Solution Architect | Legacy Systems, Integrations, Kafka & Cloud
Gdansk, Poland - 2:20 pm local time
Many organizations depend on software that has been running for years. These systems are often difficult to maintain, poorly documented, tightly integrated with other platforms, and risky to change. This is where I can help.
I am a hands-on Solution Architect and Senior Java Engineer with experience in enterprise systems, legacy modernization, system integration, security, and cloud-native development.
My typical projects include:
• Java 8 → Java 17/21 migrations
• Java EE / JBoss → Jakarta EE / Spring Boot modernization
• SOAP to REST integration layers
• Keycloak and IAM implementations
• Kafka and event-driven architectures
• Kubernetes and OpenShift deployments
• API-first development with OpenAPI
• Integration and E2E testing using Testcontainers, Cucumber and MockServer
Unlike many architects, I stay close to the code. I regularly work on implementation, troubleshooting, performance issues, integration challenges, deployment pipelines and production support.
I have worked in healthcare, insurance, telecommunications, logistics and public-sector-related environments where reliability, security and maintainability are critical.
If your team needs help modernizing an existing system, improving architecture, solving integration problems or preparing a realistic migration strategy, I would be happy to discuss the project.
