Java developer building Jakarta EE 10 applications, including a Java 17 PDF viewer for secure file access.

I'm developing private enterprise Java applications with Java 17 and Jakarta EE 10. My PDF Viewer project provides browser-based access to processed previews of technical drawings, with authorized downloads and printing.

At FedEx Express Europe, I developed systems for automated logistics and took ownership of CRISP, the Shipment Inventory System for sorting facilities. Earlier, I maintained mission-critical FX trading systems at Silverlink Technologies GmbH and contributed to a banking system project at Sygnity S. A.
