Tom Cassimon is a Senior Java Developer and Cloud Architect with 11+ years of experience building and migrating enterprise banking applications to Azure and Kubernetes. He combines deep Java back-end expertise (Spring, Hibernate) with practical cloud automation skills—Terraform, Helm and GitHub Actions—to enable zero-downtime upgrades and faster time-to-market. His career began on low-level C/HP-UX systems and spans work in C++, C#, PHP and Unix/Linux operations, giving him a rare full-stack operational perspective. At Argenta he helped transition branch and mobile services into a cloud-native integration layer, prioritizing fit-for-purpose Azure components and simplicity to avoid configuration sprawl. A pragmatic problem-solver, he also brings hands-on security and systems-engineering experience from earlier banking projects, plus freelance consultancy work that sharpens his ability to deliver production-grade solutions.
