Tech stack

# Tools chosen to _last._

We pick tools that are well known, well documented and easy to hire for, so what we build can be looked after for years, by us or by anyone you choose.

01 The tools

## What we _build with._

Choose a group to see everything in it.

**Frontend:** React, Next.js, TypeScript

**Backend:** Node.js, Express, Python

**Database:** PostgreSQL, MongoDB

**AI:** LLMs, RAG, AI Agents, Vector Databases

**Cloud:** AWS, GCP, Vercel, Cloudflare

02 The reasons

## Why these, _and not others._

-   ### Frontend

    React, Next.js, TypeScript

    React and Next.js render pages on the server, so they load quickly and search engines can read them. TypeScript catches many mistakes while the code is written, before a visitor ever meets them.

-   ### Backend

    Node.js, Express, Python

    Node.js and Express run the APIs and admin panels behind a site. Python takes the work that is heavy on data or on AI, where its libraries are strongest.

-   ### Database

    PostgreSQL, MongoDB

    PostgreSQL when the data has firm relationships, such as orders, invoices and accounts. MongoDB when its shape changes often, such as content, menus and catalogues.

-   ### AI

    LLMs, RAG, AI Agents, Vector Databases

    Language models through their APIs, grounded in your own documents with retrieval, so an answer comes from your material and can be checked against it.

-   ### Cloud

    AWS, GCP, Vercel, Cloudflare

    Each project is hosted where it fits: Vercel for Next.js sites, Cloudflare in front for speed, AWS or Google Cloud for heavier back ends.
