      OkCapsule notes that it's rare to find a team like Sunrise Integration that combines technical expertise with exceptional people skills. Its mix of intelligence and charm was appreciated throughout the partnership. The objective was to transition the infrastructure of a custom e-commerce application to support headless commerce across different platforms. Impressively, Sunrise Integration completed the job below the estimated budget and faster than anticipated. (Verified via email)
