Car-Booking REST API for a Mobility Platform

Overview

A Node.js REST API service that manages car bookings for a car-sharing / mobility platform. It sits between the consumer-facing booking apps and the upstream mobility fleet-management system, exposing a clean booking interface backed by a configurable fleet model.

The Challenge

The platform needed a dedicated booking backend that could talk to a third-party fleet/mobility provider’s configuration endpoints while presenting a stable, JWT-secured REST surface to its own web and build clients. Bookings had to be fleet-aware (each operating region/fleet has its own configuration) and deployable as a self-contained container.

What We Built

An AdonisJS 4.1 API application organized into Controllers (application, config and uptime/health endpoints), Services, Models, Middleware and Ace CLI Commands. Fleet behavior is driven by JSON configuration (default_fleet.json, fleets.json, default_language.json) so a single codebase serves multiple operating fleets by name. Authentication uses JWT via AdonisJS Auth; persistence runs through Lucid ORM with interchangeable SQLite / MySQL / PostgreSQL backends. The service ships with a Dockerfile and a staging docker-compose, GitLab CI, and structured logging through Winston with syslog transport. Internal registration routes are flagged for network-level protection.

Technologies & Approach

AdonisJS was chosen for a batteries-included MVC + ORM + auth stack on Node.js, keeping the booking domain logic concise. Axios handles outbound calls to the fleet provider, Moment manages time/availability windows, and the multi-driver Lucid config lets the same API run on a lightweight SQLite box or a production Postgres/ MySQL cluster.

Outcome / Impact

Delivered the booking backbone of the mobility product, maintained across roughly three years of activity (2019–2023). It demonstrates building integration-heavy, fleet-configurable services that bridge a studio’s apps to an external mobility platform.

Capabilities Demonstrated

• REST API engineering on Node.js with AdonisJS
• Multi-tenant/fleet configuration driven by JSON
• JWT authentication and route-level access control
• Pluggable persistence across SQLite, MySQL and PostgreSQL
• Containerized delivery with Docker, docker-compose and GitLab CI
• Third-party mobility/fleet API integration
