Systems Architect / Fintech Specialist / Team Lead

With over 23 years in the trenches of software development, I’ve evolved from a Java developer into a Systems Architect focused on high-stakes payment industries. My career hasn’t been just about writing code; it’s been about engineering resilience. I’ve led teams of 5 to 10 engineers, navigating the complexities of multi-tier architectures and ensuring that systems handling over 100 TPS remain rock-solid under pressure.
My expertise is deeply rooted in the banking sector and payment processing, where I’ve repeatedly guided organizations through the rigorous demands of PCI DSS and SSS certifications. I don't just build applications; I build secure, compliant ecosystems. From the initial strategic analysis to final deployment, I bridge the gap between complex business logic and high-performance infrastructure.
My professional journey has been truly global, delivering high-level solutions for clients across Switzerland, the UK, and Germany, all the way to Los Angeles and Hawaii. While my core is in Java (J2EE), my modern toolkit is built around Docker, Kubernetes, and a wide array of data environments-including DB2, Oracle, PostgreSQL, and MariaDB. Whether it’s a massive banking migration or a small, precision-focused project, I thrive on solving architectural puzzles that require both technical depth and clear leadership.
