Day One: Getting Back on the Keyboard

After years of people management, I'm rebuilding my engineering skills from scratch. Here's why — and the plan.

#rebuild#learning#ai

I’ve been a manager for a long time. A long time. My last meaningful production commit was years ago. My PR reviews were mostly about process, not code. My hands got soft.

This is the start of a rebuild.

Why Now?

Three reasons:

  1. The agentic era changes everything. AI-assisted coding, agentic workflows, the entire landscape has shifted. If I don’t learn this, I’ll be irrelevant.

  2. I miss building. There’s a specific joy in making something work — the dopamine hit of a green test suite, the satisfaction of shipping. I want that back.

  3. Leadership requires empathy. I can’t credibly lead engineers if I don’t understand what their daily work feels like in 2026.

The Plan

I’m going to learn in public. Every project, every failure, every “aha” moment goes on this blog.

Phase 1: Foundations — Modern JavaScript/TypeScript, React, the ecosystem that’s emerged.

Phase 2: Full Stack — Build actual applications. Frontend, backend, infrastructure.

Phase 3: Agentic — Build with AI agents, not just with AI assistance.

The Rules

  • Ship fast. Done > perfect.
  • Write about everything.
  • Ask stupid questions publicly.
  • No ego — I’m a beginner again.

Let’s go.
