Hostaway + MIRA
Hi, I worked with Rajneesh from Bolder Technologies on our Hostaway API integration project. He helped us with calendar sync, quote generation, add-ons, coupons, and a custom checkout system integration.
The project had some complex requirements, but he handled everything smoothly and was very responsive throughout the process. Communication was easy, and the final system worked exactly as we needed.
I’d definitely recommend him for custom API integrations and booking website development.
