🎓 Master’s in Systems Architecture 💻 10+ years building production backend systems in .NET 🤖 AI integrations in C#/.NET: MCP, RAG, LLM agents, voice AI 🏥 Domains: medtech, e-commerce, AI products 🚀 Experience across enterprise (€1B+) and high-growth startups 👥 Led engineering teams of up to 20 developers I’m a Senior .NET Engineer building AI-powered backend systems. With 10+ years in production .NET, from €1B+ enterprises to unicorn startups , I focus on embedding AI directly into existing platforms. AI & LLM Integration - MCP servers connecting AI to your tools, APIs, and data - RAG pipelines: ingestion, embeddings, vector search - OpenAI, Azure OpenAI, Semantic Kernel integrations - Agentic workflows: tool-calling, reasoning, automation - Voice AI: real-time STT → LLM → TTS, webhooks, CRM sync Backend Engineering - Scalable APIs: .NET 8+, ASP.NET Core, REST, gRPC - Microservices: Docker, Kubernetes, Kafka, RabbitMQ, Redis - Observability: App Insights, Serilog, Prometheus, Grafana - Legacy modernization with clean architecture & testing - Performance: caching, async, background jobs Most AI engineers work in Python. I build natively in C#/.NET, so AI integrates directly into your stack. Need MCP, RAG, voice AI, or all three in production? Let’s talk.
