What is covered
A hired developer covers the full backend delivery cycle: designing and documenting REST or GraphQL API endpoints, implementing business logic in TypeScript (a statically typed superset of JavaScript), connecting to databases such as PostgreSQL (an open-source relational database management system), MongoDB (a document-oriented NoSQL database) and Redis (an in-memory data structure store used for caching and pub/sub messaging), and configuring Docker containers and CI/CD pipelines. For real-time features, developers implement WebSockets, a protocol enabling full-duplex communication over a single TCP connection, to support chat, notifications and live dashboards. Frameworks used include Express.js (a minimal Node.js web application framework), NestJS (a TypeScript-first Node.js framework for scalable server-side applications) and Fastify, selected based on your architecture requirements. See REST and GraphQL API development services for project-based API work.
