Plain Markdown, Stable IDs, and Two-Layer State: Patterns From Building a PM Assistant Plugin
I built a Claude plugin for a PM on my team — daily briefing across seven tools, a live action dashboard, and a markdown vault that grows over time. Here are the patterns that survived, the ones that didn't, and the install bug that cost me half a day.
How I Build Custom Skills for Claude Code (And Why You Should Too)
The thought process behind creating reusable skills that turned repetitive dev workflows into one-command automations — from Jira-to-PR pipelines to automated verification.
My Claude Code Workflows After 280+ Messages
A look inside my actual Claude Code usage — the workflows that stuck, the friction I hit, and the practical tips that made me more productive as a frontend developer.
Using AI for Frontend Architecture Decisions
A practical look at how AI tools can help senior developers think through complex frontend architecture decisions — with real examples from production projects.
Building with AI: My First 30 Days
How I integrated AI pair programming into my daily workflow as a senior frontend developer, and what surprised me most about the experience.
