The backend tools behind our apps, bots and workers
The backend saves records, confirms payments and sends messages. Two languages cover it in our work.

Where we use it
Need an API, a background worker or a bot built?
We build those in Node.js and Python. Node.js handles the app itself: saving records, serving an API, running a messaging bot. Python takes the work that leans on its data and audio libraries, such as cleaning or scoring records and handling speech. Most projects need only one of the two, and the section below is how we decide.
When one language is enough
A second language means a second deployment and a wider hiring brief. A project that only needs Node.js is simpler with Node.js alone. Python is worth adding when a job leans on Python’s data or audio libraries.
How a request moves through
In a typical app that uses both, a request reaches the Node.js app, which saves it to the database and answers straight away. Work that needs Python goes to a Python service, either through a queue or by calling its FastAPI endpoint, and the result is written back where the Node.js app can show it.
Connected layers
Records live in the data layer; screens come from the frontend. These tools support our web apps and voice agents. The full tool list is on the tech stack page.
