    How I Actually Use Claude Code Day to Day

    Not the demo workflow. The unglamorous, high-leverage things a terminal agent is genuinely good at once you stop asking it to write your app for you.

    Designing an API Your Frontend Actually Wants

    Most frontend complexity is a backend design decision arriving in disguise. What changes when the same person builds both.

    React Re-renders: The Mental Model That Fixed My Performance Problems

    I spent a year sprinkling useMemo on things. Then I learned what actually triggers a re-render, and deleted most of it.

    Angular Signals in Practice: Replacing RxJS Boilerplate in a Real Dashboard

    Signals didn't kill RxJS in our codebase — they killed the ceremony around it. Here's what actually changed when I migrated a live HRM dashboard.

    Scoping a Feature So It Actually Ships

    The feature that took four months was supposed to take three weeks. It wasn't an estimation problem — it was a scoping one.

    State Management in React Without a State Management Library

    Most apps reaching for Redux have three kinds of state and are treating all of them the same way. Separate them and the library becomes optional.

    Cursor vs Claude Code: Which One I Reach For, and When

    They're not competitors so much as different shapes. One lives in the editor, one lives in the terminal, and the shape decides the use case.

    Writing a CLAUDE.md the Model Actually Follows

    Most project instruction files are wishlists. The ones that work are short, specific, and say what not to do.

    Standalone Components: How I Restructured a Large Angular App Without Stopping Feature Work

    NgModules weren't the problem — the dependency graph they hid was. A file-by-file migration path that never needed a code freeze.

    Design Tokens for Developers: Stop Writing Hex Codes

    A dark mode that took an afternoon instead of a sprint, and the naming scheme that made it possible.

    Angular vs React: How I Actually Choose, After Shipping Both in Production

    Not a feature comparison. The three questions I ask about the team and the product before writing a line of code.

    Angular Change Detection: OnPush, Zoneless, and What Actually Makes an App Fast

    Most Angular performance problems aren't change detection. But when they are, the fix is rarely the one people reach for first.

    AI Code Review: What It Catches, and What It Will Never Catch

    After a few hundred AI-assisted reviews, a clear pattern: it's excellent at local correctness and blind to whether you built the right thing.

    Angular Reactive Forms at Scale: Typed Controls, Dynamic Fields, and Cross-Field Validation

    The Frontend Folder Structure That Survived Three Rewrites

    Organise by feature, not by file type. Sounds obvious; almost nobody does it, and the cost compounds quietly.

    The Backend Skills That Made Me a Better Frontend Developer

    Four things I learned on the server side that changed how I write client code — and why 'full stack' is about judgement, not a longer skills list.
