About Elias
Senior Software Engineer with 8 years of experience in Java/Kotlin, Spring Boot, and cloud platforms (Kubernetes/OpenShift) across banking, public sector, and connected-traffic systems.
Currently at Raiffeisen Switzerland: I build and run the full stack for internal chat applications with 1,000+ daily users — including production RAG/LLM pipelines that reached 98% answer correctness on an expert-validated evaluation set.
My background extends beyond the JVM: latency-critical C++ in eye tracking (SDK integrated by OEM partners including AMD) and a co-founded audio startup with 1,000+ customers. M.Sc. in Bioinformatics with a Max Planck thesis on neuroevolution.
On the side: an EEG-BCI prototype for robot-arm control (Python, C++, ROS2).
