PROFILE

Sebastian

Sebastian Alfers developed and modernized the docker/compose-for-agents repository over three months, focusing on containerized AI agent workflows using Java, Docker, and Akka SDK. He built a demo application that integrates a GPT-4o-mini-powered chat agent with a streamlined UI, enabling real-time interactions through session management and server-sent events. Sebastian implemented secure, secret-based OpenAI API key handling and refactored deployment to use Docker-based builds with direct Maven execution, removing legacy scripts for reliability. He updated documentation and demo assets to support onboarding and reproducibility, demonstrating depth in environment management, integration testing, and security while laying groundwork for future CI/CD improvements.
