Germany-wide Vehicle Rental Platform

I planned, designed, built, and deployed an online rental platform for a Germany-wide vehicle rental chain.

It is built on Laravel 12 and the rapid application development framework Filament, which made it possible to build a complex multi-portal app with exceptional speed and reliability.

The platform includes:

• A public-facing front end for browsing and booking
• A customer login area for managing bookings
• A franchisee portal for station-level operations
• An administrator area for full platform management

Full Rental Lifecycle via QR Code

Bookings and fleet management work in real time. The entire rental lifecycle — pick-up, incident reporting, and return — is handled from within the app. Real-world actions like vehicle pick-up and return are triggered via QR codes, making the process fast and paperless.

AI-Accelerated Development with Conductor

Laravel's strict conventions for the location and structure of data and business logic make it exceptionally well-suited for AI-assisted development — the predictable organization lets coding agents work accurately and confidently.

Using Conductor, a multi-agent tool for macOS, I worked on several major features simultaneously in separate git worktrees — with fine-grained control and review of every line of generated code. Combined with Claude Code and ChatGPT Codex, I estimate the total programming time was reduced by 50–75%.
