Frontend Lead · Software Engineer
Mohammad Hosseini
I design and build frontend systems that scale beyond a single product.
Rather than solving the same problem repeatedly across projects, I turn recurring problems into reusable systems — reducing duplication, improving consistency, and making the next product faster to build.
Eight production projects later, this site is where I expose the engineering behind them.
You can see a live work sample of mine below — a theme engine running in the page, not a screenshot of one. The full source of this site is public.

The machine that builds storefronts
This is the config a client theme actually is. Nine axes compile into a full token system — colour, rhythm, shape, type — and into the storefront’s structure. Edit the JSON or move a control; they are two views of the same file.
