About

I am a senior software developer with 20+ years of experience in .NET development and a PhD in Computer Science. I work with clients on software that has to be reliable, maintainable, and useful in real business environments.

My background spans finance, energy, research, healthcare, transport, and industrial software. I have contributed as a hands-on full-stack developer, dev lead, Scrum master, and technical problem-solver, usually in systems where delivery pressure, legacy constraints, and operational complexity all exist at the same time.

I am strongest when I can combine backend engineering, cloud delivery, and product-facing work: designing APIs, building web applications, integrating Azure services, improving existing systems, and helping teams ship practical solutions without unnecessary complexity.

My contribution typically covers the full software lifecycle: requirements analysis, solution design, architecture, implementation, testing, deployment, troubleshooting, and collaboration with stakeholders and delivery teams. Where needed, I also take on technical leadership and coordination responsibilities.

Core areas I work in include .NET backend and APIs, Azure cloud solutions, full-stack web delivery, legacy modernization, and technical leadership.
