Writing
The commentary on the work. Some of it is long, some of it is a paragraph. Missing a week is fine. Missing direction is not.
Learn
Things I've figured out. Mental models, patterns, tradeoffs, lessons that age well.
Journey
Things I’m experiencing. Career longevity, learning later, staying relevant without chasing.
Notes
Shorter observations that didn't need to become essays. A discovery, an opinion about a tool, something a project taught me.

Stop Coding, Start Supervising
In a bold statement at CES 2026, Nvidia CEO Jensen Huang told engineers to stop writing code and start supervising it. This post explores how that single line reveals a major paradigm shift in software engineering—from coding as craft to AI-guided orchestration. For veteran developers, it’s not just a workflow change—it’s an identity crisis. And it’s not limited to tech. Drawing inspiration from adjacent fields like design, this post argues that engineers aren’t being replaced, but promoted.
AI is Fast, Production is Fragile
AI can write code fast — but production is fragile. A practical look at why bad prompts cause real outages, and the system I use to apply AI safely in real software engineering.
From Next.js to Astro: A Migration Journey
After starting with Next.js, I discovered Astro's content-focused approach was perfect for my blog. Here's what I learned during the migration.
