Tinkering with automation, AI, and whatever breaks along the way.
Query Anything with DuckDB — From Live APIs to a Finished Report
DuckDB lets you query files, folders, and live web APIs with ordinary SQL, no import step required. A small project pulling stock prices and SEC filings into an HTML report shows the reusable techniques for wrangling nested JSON from any API.
I Built a Virtual AI Team That Actually Works Like a Real One.
Skill files and instruction scripts hit a ceiling fast — skill rot, scope bleed, context dilution. Replacing them with a small team of role-based AI personas solved problems no amount of better scripting could.
Engineering Methodology in the LLM Era: Why Your Abstractions Are Now Technical Debt
LLMs have shifted the cost-benefit analysis of software design. Four principles for engineering when an AI, not a human, is the one navigating your codebase.
The Rise of the Software Factory — Orchestrating Autonomous Development
Software engineering is shifting from manual coding to a "software factory" model, where autonomous agents orchestrated through tools like Vibe-Kanban handle design, testing, and repository management in parallel.
Create Custom n8n Nodes
A complete, hands-on guide to building a custom n8n node with the n8n CLI — scaffolding, implementing an XSLT processor, testing locally, and deploying to a self-hosted Docker instance.
Build a Real-Time SQL Dashboard with n8n and amCharts (No Backend Required!)
How to build a production-ready business intelligence dashboard — live SQL Server queries, amCharts visualizations, and a custom background — served entirely through a single n8n webhook.
Using n8n as an Application Designer — From Workflow to .NET Web API
Combining n8n's visual workflow designer with Claude Code to turn a validated workflow design into a working .NET Web API — and an MVC UI on top of it.
Visual Software Development — Claude Context Engineering from Mermaid Charts and Pseudo Code, to Working C# Code (Part 1)
Building a Claude Code context for a .NET C# user-registration feature — from pseudo-code and Mermaid flowcharts to a reusable foundation for AI-driven code generation.
Visual Software Development — Claude Context Engineering from Mermaid Charts and Pseudo Code, to Working C# Code (Part 2)
Taking the Part 1 context — pseudo-code, flowcharts, and a class diagram — and guiding Claude to generate, test, and refactor working .NET C# code for a User Registration workflow.
Effortless Workflow Documentation — How to Use n8n and AI
Keeping process documentation in sync with a changing n8n workflow is tedious by hand. Here's how we pair an exported workflow JSON with Claude to generate and maintain it automatically.
n8n — for Easy Extract, Transform and Load
A walkthrough of designing a simple ETL pipeline in n8n — syncing a drop-shipping supplier's CSV inventory feed into a retailer's SQL Server database.
