Why your vault index matters more than your note count
Hoarding notes doesn't scale with AI. How an _INDEX.md became the vital contract to stop my agents from breaking the blog.
My B2B tech stack: How I use NotebookLM and Obsidian to close healthcare deals
Selling clinical software requires processing hours of meetings and dense PDFs. Here is the AI workflow I use to turn raw documents into lethal proposals.
AI does not fix broken processes: it accelerates them
Before automating with AI, teams need to map decisions, data, traceability and rules. If we automate chaos, we only get faster chaos.
NEW, REVIEW, DUPLICATE: the guard that stops a content agent from writing the same post ten times
How I designed a deterministic three-state guard to prevent my content agent from repeating topics on the blog
Field Engineering: How We Built a Portable Molecular Lab in Patagonia

How I built a system that extracts AI memories from a VPS, organizes them in Obsidian Karpathy-style, and publishes articles automatically to a blog, X.com, and LinkedIn.
MCP / Tool Use: The Future of Real Tool Integration
How Model Context Protocols are revolutionizing the way AI agents interact with external tools to execute complex tasks.
One Week of Building: 82 Decisions That Shaped an AI Product
What Engram's memories reveal about a real week of development: bugs caught, architecture hardened, and the invisible decisions that make a medical agent work.
From Equipment on the Street in Full Lockdown to Building AI Agents in Patagonia
I'm not the developer who learned to code on YouTube. Twelve years solving real problems in healthcare, management and business before writing a single line of code. This is the story.
Cotocha: the agent orchestrator that runs my life from a VPS
How I built an AI agent system that handles infrastructure, alerts, databases, and blogging from a server in Germany. No middlemen, no fancy dashboards.
