Java and Spring backend development
Java and Spring services, REST and SOAP APIs, and integrations built to run reliably in production, not just to pass a demo.
Open to senior backend roles, architecture reviews, and consulting
Senior Java and Spring Boot engineer for business-critical systems.
I build, modernise, and support Java and Spring Boot backend systems, APIs, and integrations across insurance and pensions, digital banking, fintech, and enterprise platforms.
More than a decade shipping and supporting systems where uptime, security, and careful change really matter.

How I Can Help
Focused backend and architecture support
Production-minded support for teams that need senior Java and Spring delivery, an architecture review, or backend-led AI integration.
Architecture and delivery review
A second senior perspective on your system, catching reliability, data-accuracy, and maintainability issues before they reach production.
Backend-led AI integration
AI and chatbot features wired cleanly into your existing services, with the same care I bring to any backend work.
Value proposition
What I bring to senior engineering and architecture roles
The value is not only in writing the code. It is in understanding the system around that code and keeping delivery steady.
Strong backend ownership
Most of my work is Java services, integrations, and data-heavy workflows, along with the release and support work that goes with them.
Comfortable in regulated domains
Insurance, pensions, banking, and fintech shaped how I think about security, data accuracy, operational stability, and controlled change.
Architecture that stays close to delivery
I take on architecture and solution design, but I keep it tied to implementation so the design survives production and future change.
Responsible AI adoption
I treat AI like any other backend concern. It has to prove real value, integrate cleanly, and stay supportable once the novelty wears off.
