Migrating a JTL-Shop to Shopify: What to Import and What to Skip
There is no one-click connector from JTL-Shop to Shopify. Here is how I planned a real migration - what I imported, what I deliberately did not, how scripts verify the result, how to stop notification mails during an order import, and the launch checklist.
Scheduled AI Agents — What Weeks of Unattended Runs Teach You
Notes from running scheduled, unattended AI agents for a few weeks — a daily upstream-sync job, a research agent that publishes a page, and review-bot tuning. Guards, state files, failing publish steps, and where it breaks.
Proving Where Data Stops — How I Debug Multi-System Integrations
A shop field that never updates, a CDN that can't find its images, a sync that "randomly" skips entries. A method for multi-system integrations — instrument every hop, read the boundary evidence, hand over proof instead of opinions — with five real cases from the last weeks.
Personalized Products and Packaging Fees in Shopify
How I modeled printed cups with tiered prices and a logo upload in Shopify, and the options I weighed for passing a per-item packaging licence fee through to customers — with the pitfalls I hit.
Purging Cloudflare's Cache Automatically on Every Netlify Deploy
This site sits on Netlify behind Cloudflare, and after every deploy Cloudflare kept serving stale HTML. Here's why the Netlify-CDN-Cache-Control header was a dead end for static files, and the 26-line build plugin that purges Cloudflare's edge cache the moment a deploy goes live — including the CJS/ESM gotcha that broke the first build.
Upgrading pg-boss 10 → 12 When There Is No Migration Path
pg-boss 12 cannot migrate a v10 schema - v11 moved job storage to partitioned tables and the migration chain starts after that cliff. Here's how I upgraded a production job queue anyway - drop the schema, rebuild queue state from my own tables, and the job-ownership guard the rollout taught me to add.
I Built My Own SEO Crawler - Architecture Notes from seo-pulse
Instead of paying for Screaming Frog or Ahrefs, I built my own SEO audit tool - a Bun monorepo with a Nuxt 4 UI, a pg-boss worker that crawls and scores sites, and an MCP server so AI agents can trigger crawls and read findings. Here's the real architecture, and the parts that hurt - deploys killing workers mid-crawl, queue schema upgrades, and Docker builds dying without an error.
Claude Code in Real Client Work — Workflows, MCP, and Where It Breaks
A year of running Claude Code on actual freelance and agency projects — the workflows that hold up, why MCP is the real game changer for client work, the failure modes nobody puts in demos, and what I promise clients about AI-assisted development.
Nuxt 4.5 - Vite 8, Rspack 2, SSR Streaming, and the Road to Nuxt 5
Nuxt 4.5 is the biggest release in a while - Vite 8, an Rsbuild-powered Rspack 2 builder, experimental SSR streaming, stable error codes, and a pile of groundwork for Nuxt 5. Here's what actually matters, what to test before upgrading, and why the Nuxt 3 clock is about to run out.
The Real Variable in AI Coding Isn't the Model — It's the Harness
Benchmarks show that switching edit formats improved Grok Code Fast by 10x — zero training compute required. As a developer who relies on AI agents daily, the harness deserves far more scrutiny than we give it.
Oh My Pi — The Open-Source Coding Agent I Actually Use Every Day
Oh My Pi is a fork of Mario Zechner's Pi coding agent with ~1,300 commits of incremental improvements. Here's what makes it different, why harness quality shapes agent reliability more than model choice, and why I run it instead of Claude Code.
The Supply Chain Is the New Attack Surface - npm Worms and Slopsquatting in 2026
A self-replicating npm worm and AI-hallucinated packages are the supply-chain threats hitting JavaScript developers right now. Here's how they work and how I lock my projects down.
