about()

Systems that hold up under real business load

I'm a results-driven Full-Stack .NET Developer specializing in enterprise application development, ERP solutions, and system integration. I build scalable applications with ASP.NET Core, Blazor, SQL Server and RESTful APIs — with hands-on experience across Frappe ERP, Docker, Nginx, Umbraco CMS and cloud-based deployments.

My focus is on designing business-critical systems, integrating third-party services, and shipping maintainable, high-performance software that supports complex workflows — not just demos that work on a happy path.
