Product surfaces
Next.js and React applications with routing, account areas, and interface states that match how the product is actually sold.
Product engineering
TypeScript
Typed web platforms, APIs, and product UI — one language from the domain model to the screen.
We use TypeScript when a product needs a shared language across the interface, the API, and the rules of the business. The compiler is the means. The result is a codebase a small team can change without guessing which shape a payload will take.
Most of this work is Next.js and React on the surface, with Node or edge handlers behind it. We also adopt TypeScript inside an existing JavaScript product, one boundary at a time, when a rewrite would throw away software that already earns its keep.
TypeScript
What the work covers
Typed APIs
HTTP or RPC handlers whose inputs and outputs are checked against the same types the client uses.
Shared domain models
The nouns of the business — accounts, plans, orders, permissions — defined once and imported where they are enforced.
Design-system implementation
Components that match an existing brand, including the awkward states: empty, loading, partial, and denied.
Auth and permissions
Sign-in, invitations, roles, and the checks that keep one customer’s data out of another customer’s session.
Incremental adoption
A typed boundary around a legacy JavaScript module, so the next change is safer without a flag-day rewrite.
Delivery
What you leave with
- A web product a team can run in preview and production
- API contracts checked at the boundary
- A component layer later pages can extend
- Notes on how to add a feature without inventing a second pattern
Fit
Choose this when
- The product is primarily a website or web app.
- One language across UI and API will keep the team smaller.
- You expect the interface to change often in the first year.

When another practice fits better
These are the switches we recommend in scoping, not a disclaimer.
