At Jinius Ltd (Bank of Cyprus), I lead technical merchant onboarding and work with merchant development teams on REST API, XML, CSV, and XLSX integrations. I validate feeds before production deployment and use Python scripts and regular expressions to automate data validation.

Previously, I developed Oracle BRM products at Cablenet Communication Systems PLC and real-time charging functionality at Amdocs Software Systems Ltd. My work also included SQL-based billing investigations, application testing and debugging in Linux/Unix environments, and maintaining IT equipment at European University of Cyprus.
