I've spent the last decade or so building backend systems for banks and fintech companies. Most of my work lives at the infrastructure layer - Java services with Spring Boot and Project Reactor, running on Kubernetes, across AWS, Azure, and Oracle Cloud depending on who the client is.
Alongside the development work, I handle the ops side too - infrastructure, deployment pipelines, monitoring. Owning the full path from code to production means fewer surprises and fewer handoffs.
