Sean M.
MVP Engineer | Full-Stack .NET Developer (Azure, OpenAI, Automation)
I’m a senior full-stack engineer specializing in building scalable web applications, automation pipelines, backend services, and AI-powered integrations. I’ve spent the last several years architecting enterprise systems that support mission-critical operations at national scale. Most recently, I designed and deployed massive-scale data integrations across an entire national K–12 education system—supporting 20,000+ schools and 13 million students, with platforms used daily by tens of thousands of administrators. I bring that same level of care, clarity, and engineering rigor to every client project, big or small. What I can build for you: • Custom web applications using C#, .NET, Blazor, and modern JavaScript • API integrations, automation workflows, and backend services • AI-powered features using any model provider (Azure OpenAI, OpenAI, Anthropic, Llama, etc.) • Secure cloud architectures using Azure Functions, serverless patterns, and identity systems • Power BI and Microsoft ecosystem integrations (REST API, automation, identity/security workflows) • MVPs and internal tools to streamline business operations and validate new product ideas What you can expect when working with me: • Clear communication and consistent delivery • Clean, maintainable, scalable code • Ability to take a concept from idea → architecture → implementation → deployment • Ability to work solo or integrate seamlessly into an existing engineering team If you need a developer who can own a project end-to-end—or jump into an existing system and make it better—I can help.
