GlobalRental: car rental marketplace in Montenegro

A marketplace where local rental companies list their cars and tourists book them online. I was the technical director: first I managed the contractor, then wrote the code myself.

Most rental companies in Montenegro are small, and many of them have no proper website. GlobalRental pulled their cars into one catalog. A tourist picks a city and dates, sees the price with deposit and delivery right away and books without signing up. Each rental company gets its own dashboard: cars, a booking calendar, customers, seasonal prices.

I joined on the investor’s side at the end of 2023: I wrote the specs, signed off the contractor studio’s milestones and set up production and deployment. In 2024 I wrote code alongside the studio’s developer and owned the emails, a Telegram bot for booking alerts, Sentry error monitoring and the admin panel with stats. From late 2024 I ran the code alone: frontend, backend and infrastructure. 331 of the 645 frontend commits and 136 of the 294 backend commits are mine.

Over that time the product got car onboarding by VIN with a photo of the registration document, car moderation in the admin panel, five interface languages and four currencies, and in 2025 yacht rentals. Card payments went through Stripe and were tested with a live payment. In spring 2025 we opened partner sign-up, and 15 rental companies registered in the first ten days.

Online payment never reached real customers: ads brought no leads, and in 2025 the investors stopped the project.
