After 15 years of building web applications, I've learned what separates a project that works from one that lasts — thoughtful architecture, clean code, and honest communication.
My sweet spot is .NET-heavy full-stack development with a particular depth in Umbraco CMS customization. I'm the developer you bring in when the backend needs to be solid, the CMS needs to be tailored, and the frontend needs to hold up under real-world use.
What I specialize in:
.NET & Backend Development
C#, ASP.NET Core, MVC, REST API development, Web API, SQL Server — building scalable backends for SaaS applications, enterprise platforms, and client-facing portals.
Umbraco CMS Development
Certified Umbraco Expert with deep experience in CMS customization, multi-site builds, headless Umbraco, and content architecture for e-commerce and corporate sites.
Frontend Development
Angular, React.js, SCSS, Bootstrap, HTML5 — clean, responsive UIs that integrate tightly with .NET backends.
Cloud & Infrastructure
Azure deployment, CI/CD pipelines, cloud-hosted .NET applications, and Azure DevOps — getting your app live and keeping it stable.
Database & Legacy Systems
MSSQL, MySQL, Oracle, IBM DB2 — including legacy system migration, database optimization, and modernizing older .NET codebases.
E-Commerce Development
Custom e-commerce solutions built on Umbraco, integrated with payment gateways, inventory systems, and third-party APIs.
I work best with clients who have a clear problem and want a developer who takes ownership — not just someone to execute tickets. I keep my workload focused so every project gets proper attention.
Feel free to message me with what you're building — I'll tell you honestly if it's a good fit.
