Java Backend Engineer | Forex & Payments Systems | Spring Boot | Microservices

About

I am a Java backend engineer with over 3 years of experience building and maintaining systems in the forex and payments domain at First National Bank (FNB).

I work on backend services that support foreign exchange transactions and cross-border payments, where correctness, consistency, and system reliability are critical. My focus is on building clean, maintainable services using Spring Boot and designing APIs that perform well in distributed environments.

Over time, I have gained practical experience with transaction boundaries, concurrency, and system behaviour under load, and I apply this when designing and improving backend systems.
