Hire the Best Software Architecture Freelancers
in Ireland

I am an architect and builder of backend systems that handle millions of transactions, process data at scale, and stay resilient under pressure. Over 30 years of professional experience across telecoms, financial services, eCommerce, industrial automation, and high-performance computing have given me a deep understanding of what it takes to deliver systems that actually work in production — not just on paper. My career has been built on two pillars: technical depth and structured methodology. I write production code in Java (since 1996) and C++ (since 1984), and I architect the systems around it — from data models and API contracts to deployment strategies and fault tolerance. I'm equally comfortable designing a distributed architecture from scratch and diving into code to solve a performance bottleneck. Clients I've delivered for include Jet-com/Walmart, McLane, Accenture, Vodafone, Nokia-Siemens Networks, Amadeus, and several major Italian Banks. Beyond individual contributor work, I've led engineering teams in complex environments and critical projects. My approach to architecture is systematic and documentation-driven. Every engagement follows a structured process: requirements analysis, boundary condition mapping, data model definition, security strategy, component selection (with a strong preference for well-maintained open-source), API and protocol design, and deployment planning, including clustering, geo-distribution, redundancy, and fault tolerance. Security is not a layer I add at the end — it's embedded in how I think about every design decision. Zero-trust architectures, TLS/SSL, OAuth2/OIDC, RBAC, and CI/CD pipeline hardening are foundational elements, not afterthoughts. I deliver production systems that perform, scale, and hold up under real-world conditions. If your project needs an architect who also codes, leads teams, and takes ownership end-to-end — let's talk.
