🤖 What I'm building

• 🏢 AI agents for procurement at Mercanis, an AI-native Source-to-Pay platform with agents built in and integrated with legacy ERP systems
• 🧠 Agentic workflows: tool-calling agents, multi-step orchestration, human-in-the-loop approvals
• 🔌 Model Context Protocol (MCP): connecting LLMs to real business systems and APIs
• 📚 RAG pipelines: embeddings, vector search and grounding answers in enterprise data
• 🛡️ Production AI: evals, observability, guardrails and cost control for LLM apps
• 🎥 1,000+ free videos on YouTube and 500+ articles, now covering AI engineering alongside Node.js, NestJS and cloud
