⭐ Top Rated | 92 Jobs Completed | 1,200+ Hours ⭐ ***Senior Software Engineer who builds production-ready AI systems*** 🚀 Building an AI product, LLM system, or agentic workflow — but not sure how to structure it so engineers can actually ship it? I bridge the gap between AI ideas and production reality, delivering system designs, RAG architectures, and .NET backends that teams can build from day one. 🚀 With 10+ years in .NET engineering and system architecture, and deep hands-on experience in LangChain, LangGraph, OpenAI, and vector databases, I help startups and enterprises go from concept to a working, scalable AI system — without the expensive rework that kills most AI projects ━━━━━━━━━━━━━━━━━━━━━━ 🔨 WHAT I BUILD ━━━━━━━━━━━━━━━━━━━━━━ → Agentic AI systems — multi-agent workflows, tool-calling, memory & orchestration (LangGraph, CrewAI, AutoGen) → RAG pipelines — end-to-end retrieval systems with Pinecone, Chroma, FAISS, Weaviate → .NET AI backends — ASP.NET Core APIs integrating LLMs, webhooks, and microservices → AI system documentation — SRS, SDS, UML, architecture diagrams developers can build from → System architecture design — scalable blueprints for SaaS, enterprise, and government platforms → Cloud AI integration — Azure OpenAI, AWS Bedrock, Cognitive Services ━━━━━━━━━━━━━━━━━━━━━━ 🛠️ TECH STACK ━━━━━━━━━━━━━━━━━━━━━━ LangChain · LangGraph · CrewAI · AutoGen · OpenAI GPT-4o · Claude API · Pinecone · NodeJS · Chroma · FAISS · Weaviate · ASP.NET Core · .NET 8 · C# · Azure AI · AWS Bedrock · SQL Server · REST APIs · UML · n8n ━━━━━━━━━━━━━━━━━━━━━━ 📁 RECENT PROJECT HIGHLIGHTS ━━━━━━━━━━━━━━━━━━━━━━ ▸ AI Voice Agent — Designed and built a real-time voice agent with n8n automation and LLM-driven conversation flows. Result: fully automated tier-1 customer interaction, zero human handoff. ▸ AI Hotel Booking Engine — Architected a GenAI booking assistant with intent recognition, RAG-based policy retrieval, and .NET backend. Result: Result: self-serve resolution replaced manual support for common booking queries ▸ AI Contract & Compliance Platform — LLM extraction + vector DB + automated audit trail for enterprise compliance checks. Result: replaced a fully manual contract review process. ━━━━━━━━━━━━━━━━━━━━━━ 🔄 HOW I WORK ━━━━━━━━━━━━━━━━━━━━━━ 1. Understand your goals — map business requirements to AI capabilities honestly 2. Design the architecture — full system blueprint before any code: data flows, agent roles, API contracts, guardrails 3. Build iteratively — clean implementation, tested at each milestone 4. Document and hand off — SRS, SDS, UML so your team can maintain and scale independently ━━━━━━━━━━━━━━━━━━━━━━ 📩 LET'S WORK TOGETHER ━━━━━━━━━━━━━━━━━━━━━━ Most AI projects fail not because of bad code — but because of unclear architecture and missing requirements. I help you get that right first. Message me with your project idea — I'll respond within 2 hours with an honest assessment and a clear path forward. 📩
