I created an automation that lets powerful cloud language models answer questions about private company documents without ever seeing real sensitive data. The cloud model only ever receives surrogate values. Real names, passport numbers, financials and other secrets stay inside my network. This article explains how I put that together, the challenges I ran into, … Read more
Agent skills have become one of the most useful design patterns for building practical AI agents. I created an automation that combines agent skills with code execution sandboxes inside a custom Python and React agent. The result is an agent that can not only answer questions but follow step-by-step workflows, execute code safely, and produce … Read more
I created an automation that dramatically reduces unnecessary LLM context and lets the model orchestrate complex workflows with real code. The two design patterns at play are simple in concept but powerful in practice: tool search and programmatic tool calling. Both solve problems that crop up as agents grow: tool definitions bloating the context window, … Read more
I created an automation that treats a knowledge base more like a living file system than a static set of vectors. Instead of relying only on semantic search, this approach lets an AI agent actually explore folders and files, form hypotheses about where answers live, and then dig deeper—just like a developer reading a codebase. … Read more
I built a set of agentic workflows to see how far coding agents can take routine automation. I wanted to answer a practical question: when should you use a coding agent like Claude Code to generate Python workflows, and when should you stick with visual workflow tools such as n8n? I tested real examples, deployed … Read more
Overview I built a full-featured Agentic RAG application that lets an LLM interact with private company data safely, efficiently, and transparently. The stack is intentionally simple: a React frontend, a Python FastAPI backend, and Supabase for storage, vectors, and auth. I used DocLing for document parsing and LangSmith for observability. The result is a multi-user … Read more
I created an automation that turns short lived AI calls into long running, reliable agents. These agents can research, synthesize, and produce reports that span hours and many data sources. The trick was adding a control layer, which I call an agent harness, around the AI so it can plan, persist progress, and resume work … Read more
I created a multi-user AI agent that runs inside an e-commerce dashboard and can answer account-specific questions like “Where is my order?” or “Show me the invoice for order #6.” I built the agent with n8n and Supabase, and I focused heavily on security. In this article I’ll explain the full architecture, show the demo … Read more
Context engineering has become a crucial skill for anyone working with AI agents today. As these agents grow more advanced and capable of independent operation—accessing the web, knowledge bases, and various tools—the traditional approach of prompt engineering no longer suffices. The key challenge is managing the context window, which is the limited amount of text … Read more
Fine-tuning is a powerful way to transform your AI agents, making them more specialized, reliable, and aligned with your unique tone of voice. In this article, I’ll walk you through how to get started with fine-tuning, explain why and when to use it, and share a system I built using Airtable and n8n that allows … Read more
Building AI automations and agents involves understanding many concepts that help you create smarter and more efficient workflows. In this article, I will explain over one hundred of these essential concepts in a clear and practical way. This guide is meant to help you gain a solid grasp of AI automation, whether you’re just starting … Read more
I created a comprehensive crash course to help you build automations and AI agents using n8n, guiding you from an absolute beginner to a confident creator of full workflows. By the end, you’ll understand key concepts that allow you to build more advanced automations. This article breaks down the process step-by-step, explaining technical ideas in … Read more
