Experienced engineering,
focused on outcomes.

I'm a Senior Full-Stack Software Engineer with 8+ years of professional experience building software across backend, full-stack and cloud environments.

My core expertise is in C#, .NET, SQL and AWS, with a strong focus on clean architecture, maintainability, scalability and reliable software delivery.

I've worked on enterprise applications, SaaS platforms, APIs, integrations and distributed systems, collaborating with engineering teams and stakeholders to turn requirements into production-ready solutions.

I work particularly well with teams that need an experienced engineer to build features, improve existing systems, solve technical problems or take ownership of a technical initiative.
