Available to hire
I’m a Senior Full-Stack Software Engineer with 20+ years delivering backend platforms, secure APIs, modern web applications, and enterprise integrations across regulated and data-intensive environments. I build end-to-end solutions on .NET and ASP.NET Core on the backend and React/TypeScript or Blazor on the frontend, supported by robust Azure delivery and DevOps pipelines. My recent work focuses on agentic AI, Semantic Kernel, Azure AI services, and high-throughput data and payment workflows.
I thrive in multi-tenant architectures, IAM, observability, and production support, applying Clean Architecture, CQRS, microservices, and automated testing to deliver scalable, secure, and evolvable systems.
