I am a senior .NET developer with more than 25 years of experience building, modernizing, and supporting enterprise software. My core expertise is in C#, .NET Core, .NET Framework, legacy systems, API architecture, and complex business applications.
I have extensive experience with SQL and NoSQL databases, system integrations, REST and SOAP services, SAP ECC, and healthcare, finance, mortgage, logistics, and education domains. I work comfortably across both modern cloud-native environments and long-running legacy platforms.
I have delivered measurable operational improvements, including reducing critical incidents by 20%, accelerating deployments by 35%, increasing support productivity by 30%, and lowering infrastructure costs by 18%. I focus on maintainable architecture, performance, reliability, and practical business outcomes.
My technical background includes C#, ASP.NET, WinForms, WebForms, Angular, React, JavaScript, TypeScript, SQL Server, MySQL, MongoDB, Docker, Kubernetes, Azure, AWS, RabbitMQ, and Umbraco. I also have strong experience maintaining and migrating Delphi, VB.NET, VB6, and Classic ASP applications.
I apply SOLID principles, Clean Code, Clean Architecture, and Agile practices including Scrum and Kanban. I am seeking opportunities where I can contribute my experience in software architecture, application modernization, integrations, and complex problem-solving.
