Things I’ve been
working through.
JavaScript Array Internals: Memory Layout Without the Myths
JavaScript arrays are objects with specialized element storage: engines may pack dense indexed elements contiguously, but holes, mixed types, and properties force more general representations.

React Fiber: Buffers, Hooks, Lanes, and Commit
Work-in-progress buffers hold the next tree, hooks store state on fibers, lanes prioritize updates, and commit applies the finished tree in a short, ordered phase.

React Fiber: How the Tree Walk and Work Loop Actually Run
Fiber walks units of work depth-first, can pause between units, and only finishes a tree when the work loop completes without higher-priority interruption.

Hi, I’m Mohammed.
I’m a senior software engineer based in Dubai. My work spans enterprise platforms and SaaS products, from the behavior of a single interaction to the architecture of a large application.
I care about how a page feels to use and what happens beneath it. Some of that thinking becomes an article, some becomes a tool, and some finds its way into the next thing I build.
