Hi, I’m William Mittel, a senior .NET developer focused on modern Azure cloud solutions, high-performance Blazor applications, and resilient microservices. I design secure REST APIs, orchestrate enterprise integrations, and leverage data analytics to deliver reliable, scalable software in cloud-native environments.
I’ve built end-to-end solutions for government and enterprise—from In-Court Processing systems to CRM migrations—using a broad stack that includes .NET, Azure, React/Vue, Elasticsearch, and event-driven architectures. I’m pragmatic about requirements, value clean architecture and observability, and continually improve development processes to deliver high-quality software.
