How to Build Reliable AI Products: A Production Engineering Guide
AI demos are easy. Reliable AI products are an engineering problem.
Notizen, geschrieben während der Arbeit.
Technische Posts, Produktentscheidungen und ehrliche Beobachtungen — geschrieben beim Bauen, nicht danach.

How Chrome Extensions Actually Work in 2026 (Manifest V3 Explained)
MV3 is four moving parts — manifest, service worker, content scripts, and UI — not a single script tag anymore.
Personal Page - From Personal Site to Product
Stop presenting projects. Start shipping a system that compounds trust.
Build in public
Build-Log
Was shipped wurde, was kaputtging und was sich änderte — geschrieben, als es passierte.
ResistGate 1.3.3 — clearer popup, better first glance
Shipped a popup refresh focused on first-glance clarity: the popup now states the job plainly, the current-tab shortcut says exactly what it does, and the empty state lost its duplicate copy. Small release, but every session starts at the popup.
Amethyst 1.6.2 — the popup stops trying to be the dashboard
Rebuilt the Amethyst popup around one question: where did today go? It now opens with the daily total, top sites, and a single button into the full dashboard. Removed the tracking badge, comparison chip, sync button, and feedback card — the glance view answers fast, then gets out of the way.
Published the agent-readable portfolio series
A run of notes on making this site readable by AI agents: the MCP server, the public API, the data model, and the security lessons from exposing it all. Personal sites are becoming APIs — this series documents doing it for real.
KI-Engineering
Wie sich KI-Funktionen verhalten, wenn echte Menschen sie nutzen — nicht in kontrollierten Demos.
API vs MCP: When Should You Use Each?
Use the interface that matches who's reading — humans, software, or agents.
How I Would Build an Agent-Readable Personal Hub From Scratch
Start with the data model, then expose the same truth through pages, APIs, MCP tools, and examples.
Chrome-Erweiterungen
Praktische Guides für Manifest V3, privacy-first Browser-Tools und Extension-Distribution.
How to Publish a Chrome Extension to the Web Store in 2026 (Full Checklist)
The Web Store review is a product gate — privacy policy, assets, and MV3 compliance matter as much as your code.
How I Built ResistGate: A Chrome Extension That Makes You Earn Distractions
Real products need friction by design — ResistGate makes you type before distraction, not just block URLs.
Produktentscheidungen
Preise, Produktentscheidungen und was ich gelernt habe, als ich Dinge bauen wollte, die Menschen wirklich kaufen.
I Turned My Personal Hub Into an Agent-Readable Surface
A personal site should not only be browsed by people. It should also be legible to the tools people use to discover, evaluate, and remember work.
The Future of Personal Websites Is APIs
Your website should not only be visited. It should be callable.
Systemdesign
Architektur-Trade-offs, Primitive statt Komplexität und dauerhafte Systemmuster.
Content Kit: Personal Hub MCP and Public API
A technical launch is easier to distribute when the story, snippets, and proof points are already packaged.
Security Lessons From Making My Personal Hub Agent-Readable
The first rule of agent-readable systems: do not give the agent more power than it needs.
Wie ich denke
Wie ich Entscheidungen treffe, fokussiert bleibe und ohne Team vorankomme.
How I Handle Payments as a Solo Founder (ResistGate & Amethyst)
PayPal subscriptions, webhooks, and a Postgres entitlements table — the smallest stack that unlocks Pro in the extension.
The Payment Stack at Each Revenue Stage (ResistGate & Amethyst)
Freemius, Paddle, and custom PayPal each fit a different MRR band — pick the stage you're in, not the stack you wish you had.
Wie ich arbeite
Schlaf, Routinen, Lernen und was mich wirklich auf voller Kapazität hält.
