⚑ Software Engineer Senior Lead | Java | Enterprise Systems | Payments & FinTech

πŸ’¬ About Me

Software Engineer Senior Lead with 10+ years of experience developing enterprise payment systems in the financial technology sector.

Currently working at Clear2Pay (an FIS company), where I contribute to the development of enterprise payment processing platforms used by financial institutions. My work focuses on implementing backend services in Java and supporting deployment of applications using Docker, Kubernetes, and Helm. I collaborate with cross-functional teams including Developers, QA Engineers, Technical Architects, Business Analysts, and Non-Functional Testing (NFT) teams, while coordinating with other platform teams whose systems integrate with or provide components for our solution.

My work contributes to real-time payment systems supporting high-value financial transactions within European banking infrastructure, focusing on the SEPA Instant Credit Transfer (SCT Inst) scheme.

Over the course of my career at FIS, I progressed from Junior Java Developer to Software Engineer Senior Lead, gaining deep experience in enterprise software development and payment processing platforms.

Core expertise:

  • Java backend engineering
  • Enterprise payment systems (SEPA Instant / SCT Inst)
  • Backend services and enterprise system integration
  • Financial technology infrastructure
  • Containerized platforms (Docker, Kubernetes, Helm)

I enjoy working on complex backend systems and building reliable software for financial infrastructure.

Always focused on the solution - not the problem.
