High-Throughput SEPA Payment Gateway & Clearing Engine Modernization

Led architecture modernization for a Tier-1 German banking group, transitioning legacy batch clearing jobs to real-time ISO 20022 message processing.

• Architectural Implementation:
  • Designed an idempotent event-sourcing transactional ledger with event replay capabilities using Kafka and PostgreSQL.
  • Engineered resilient circuit breakers and rate limiters compliant with BaFin audit standards and PSD2 regulation.
  • Achieved 99.999% availability during peak transaction clearing windows (over €180M processed daily).
  • Cut transaction latency from batch windows down to sub-800ms real-time settlement.

codeworking.org: Distributed Systems & Java Microservices Curricula

Authored comprehensive architectural deep dives, engineering decision blueprints, and practical computer science curricula translating 15+ years of enterprise Java and microservices production experience for engineering teams worldwide.

• Architectural Implementation:
  • Published battle-tested guides on zero-downtime database migrations (splitting monolithic schemas into microservices data stores).
  • Designed complete reference implementations demonstrating Kafka event-sourcing ledgers and outbox patterns in Java Spring Boot.
  • Formulated resilient service-to-service communication guides comparing gRPC, JSON-RPC, and async messaging under failure scenarios.
  • Mentored mid-to-senior software engineers through structured architectural review rubrics and hands-on production diagnostics.
