/** JavaScript development — the language everything else builds on */

JavaScript development, done cleanly.

Every framework we use — React, Vue, Node, Next.js — is JavaScript (or TypeScript) underneath. This page is really about the fundamentals: clean, well-typed, well-tested JavaScript that whatever framework sits on top of it can actually rely on.

What we build

JavaScript, applied.

✓

Custom interactive features

Anything a template or plugin can't do — built as clean, maintainable JavaScript instead of duct-taped scripts.

✓

TypeScript migrations

Adding type safety to an existing JavaScript codebase to catch bugs before they ship.

✓

Browser extensions & scripts

Small, focused tools that live in the browser and do one job well.

✓

Framework-agnostic frontend work

Sites and features that don't need a full framework — just solid, fast vanilla JavaScript.

Is it the right fit?

How much JavaScript does your project actually need?

JavaScript is the only language that runs natively in every browser, so some amount of it is unavoidable. The real question is how much. A site that is mostly text, images and a contact form needs very little, and loading a full framework for it makes pages slower on exactly the phones and connections most local customers are using. An application with live data, complex forms, drag-and-drop or anything that updates without reloading genuinely needs a framework, and there the structure pays for itself. We make that call per project rather than per preference, and we are happy to build the simple version when the simple version is correct — it is cheaper for you to run and easier for anyone to maintain later.

FAQ

Common questions

Do we need a framework, or just JavaScript?
Depends on the project — a small interactive feature might not need React or Vue at all. We'll recommend the lightest tool that actually fits.
Should we use TypeScript?
For anything beyond a small script, generally yes — it catches real bugs before they reach production and makes larger codebases easier to maintain.
Can you fix messy legacy JavaScript?
Yes — we regularly clean up and modernize older JS codebases, adding structure and types without necessarily rewriting everything.
