Backend
Server-side technologies for APIs, integrations, application workflows, and reliable business logic.
Backend
Introduction
Backend technologies handle the parts of a website or application that don't live in the browser: processing form submissions, enforcing business rules, talking to a database, calling third-party services, and exposing data through APIs that the frontend (or another system) can consume. Where frontend work is about what a user sees, backend work is about what happens correctly and securely behind that screen.
This category covers Node.js as the runtime, Express.js for building HTTP APIs on top of it, Prisma and Mongoose as the two most common ways to talk to a database from a Node.js application (Prisma for SQL databases, Mongoose for MongoDB), GraphQL as an alternative query layer to plain REST APIs, and REST APIs themselves as the default integration pattern most third-party services expect.
When These Technologies Are Used
Backend work is required whenever a site needs to do more than serve static content — anything involving user accounts, form processing, payments, dynamic data, or communication with another system. REST APIs are the default choice for most integrations because nearly every external service (payment gateways, CRMs, email providers) speaks REST. GraphQL becomes useful when a frontend needs to pull data from several related sources in a single request and over-fetching plain REST endpoints would be wasteful. The choice between Prisma and Mongoose comes down to the database itself, not preference — Prisma for relational (SQL) data with strict schemas, Mongoose for MongoDB's more flexible document model.
