Deep dives into Angular, build tooling, and real-world engineering
Staff Engineer with 9+ years shipping production software — Angular, React, Node.js, build tooling, and the platform work that keeps teams moving.
Welcome to my blog 👨🏻💻 — long-form, hands-on articles on Angular internals, framework migrations, build tooling, debugging production issues, and how AI is changing the way we write code.
Each post starts from a problem I had to solve on a real project, written up step by step with the code, the dead ends, and the fix — the article I wish had existed when I started.
