ABOUT CAGDAS ARDA
With over 15 years of experience in backend development, I specialise in building high-performance, low-latency systems for the banking, finance, and card payments industries. My expertise spans C#.NET (Framework & Core), Microservices, Event-Driven Architecture, and TDD, consistently delivering resilient, scalable, and regulatory-compliant solutions (PCI-DSS, AML).I thrive on optimising mission-critical systems — from card authorisation engines handling 500+ transactions/sec to middleware integrations for risk management and trade processing — achieving measurable performance gains and modernising legacy systems to.NET 8 standards.Beyond coding, I have led cross-functional teams as a Scrum Master, driven Agile transformations, and designed CI/CD pipelines in Azure DevOps, enabling faster, safer delivery cycles.I’m passionate about innovation in financial technology, modern architecture patterns, and collaborating with teams to build the next generation of payment solutions.
