We rock thesetechnologies.

The library the modern web agreed on.

React is how interfaces are built now. It was created at Facebook to solve a problem every large product eventually has — keeping what the screen shows in step with what the data says — and it solved it so decisively that it became the default for the industry rather than a choice within it.

For a business that matters in a way that has nothing to do with fashion. A React codebase can be picked up by a developer anywhere in the world. The talent pool is the largest in software, the documentation is exhaustive, and the ecosystem around it means most problems you will meet have been solved, tested and written up by someone else already.

Not a framework you rent

React is open source and governed in the open. Nobody can raise its price, change its licence terms against you, or discontinue it — the guarantee no proprietary platform can offer.

Components, not pages

The interface is assembled from pieces that are built once and reused everywhere. A change to a button is a change to every button, which is why a React product gets cheaper to change as it grows rather than more expensive.

A hiring pool, not a dependency

If we disappeared tomorrow, you could hire for this. That is a deliberate property of the choice, and it is the single most important thing to ask of any agency's stack.

One language, from the browser to the database.

Node put JavaScript on the server, and in doing so removed the oldest tax in web development: two languages, two teams, two ways of describing the same thing, and a translation layer between them where the bugs live.

It is built for exactly the shape of work a modern product does — thousands of connections waiting on a database, an API or a payment provider at the same time. Node handles that concurrency on a single thread without the memory cost of a thread per request, which is why it sits under so much of the world's real-time software.

Shared language, shared logic

Validation rules, pricing logic and types are written once and used on both sides. The form cannot disagree with the server about what a valid order looks like.

Built for waiting

Most server work is waiting on something else. Node is designed around that, which is why it holds high concurrency on modest hardware.

The largest ecosystem in software

Whatever you need to integrate — a payment provider, an ERP, a shipping carrier — a maintained, battle-tested client already exists.

Thirty years old, and still the one serious answer.

PostgreSQL has been in continuous development since the 1980s and is, by a wide margin, the most capable open-source database in existence. It is the boring, correct choice — and in a system that holds your orders, your customers and your money, boring and correct is the entire specification.

It refuses to lose data. Transactions either complete or they do not; there is no state where a payment was taken and an order was not written. That guarantee sounds obvious until you have used a database that does not make it.

Correct under pressure

Full ACID transactions, enforced constraints and referential integrity. The database refuses impossible data rather than trusting every piece of code that ever touches it.

One engine, many jobs

Relational tables, JSON documents, full-text search and geospatial queries in a single system — so a product rarely needs a second database bolted alongside it.

Nobody owns it

Open source under a permissive licence, and offered as a managed service by every major cloud. You can move hosts without rewriting a line, which is the opposite of every proprietary alternative.
