The argument

A React app is just a tree of decisions.

Each branch · a contract. Each leaf · a token. Each render · a decision held.
02 — Ecosystem

React,
and the right neighbours.

Meta-framework/01
Next.js 15

App Router, Server Components, streaming, and edge-first deploys. Our default for product surfaces.

03 — What we build

Three shapes,
one toolkit.

01 — SaaS
SaaS
platforms.

Multi-tenant products. Auth, billing, admin, telemetry — wired to ship from day one.

  • →Multi-tenant auth · org / role / scopeOIDC
  • →Billing · usage + seatStripe
  • →Admin · feature flags, audit logRBAC
  • →Workspace · roles, invites, settingsOrg

02 — Internal tools

tools.

Operator UX. Tables that scale to a million rows; commands that don't pretend they're forms.

  • →Command bar · keyboard-firstcmd-K
  • →Bulk actions · undoableOptimistic
  • →Permissions · per row, per cellRBAC

09 — Questions

Things people
actually ask.

React is the lingua franca: largest hiring pool, most mature ecosystem, and the longest-running list of patterns for problems you haven't hit yet. We pick Vue, Svelte, or Solid when a project's runtime constraints make the case — but for most product surfaces, React buys the most optionality per line of code written.
Default RSC for product surfaces — better TTFB, lower JS, simpler data flow. Pure SPA for tools that live behind auth and don't need SEO or hydration latency. We pick per surface, not per project.
Tokens land as code, not as a Figma file. Components ship behind Storybook with VRT, a11y tests, and MDX docs. Designers and engineers edit the same primitives — there is no "design version" of the truth.
Yes — about half our work is brownfield. We start with a tech audit, identify the safe seams, and ship into the existing app behind feature flags. No big-bang rewrites.
Vitest for unit/integration, Playwright for e2e, axe-core for a11y, Chromatic or Playwright VRT for visual regression. CI runs the full suite on every PR; nothing ships if the suite is red.
You do. All work is delivered under a work-for-hire clause; the repo, the tokens, the runbook — all yours from day one. We keep no embedded SDKs or licensing strings attached.
10 — Start

Let's build
something worth shipping.

Two-week diagnostic, four-week MVP, twelve-week ground-up. Bring the brief — we'll send a plan, not a pitch deck.
