What I'm looking for

I’m looking for a senior full-stack role where I can build reliable ASP.NET Core microservices and AI-powered experiences on Azure—shipping fast with strong CI/CD, real-world impact, and close cross-functional collaboration.

I’m a Senior .NET Full-Stack Engineer with 8+ years delivering production-grade C# and ASP.NET Core applications across e-commerce and enterprise SaaS platforms. I build measurable business outcomes through clean architecture, CI/CD automation, and cross-functional collaboration, with strong expertise in microservice architecture and React/Angular frontends.

In recent roles, I’ve designed ASP.NET Core Web APIs integrated with Azure OpenAI Service and Azure AI Search for vector-based semantic product search and conversational commerce, and I’ve shipped real-time order-status and inventory endpoints using SignalR and Server-Sent Events. I also develop ML.NET-based personalization and integrate RAG-style solutions via Semantic Kernel, while leading backend reliability at scale with robust testing and Azure-native services.
