    He delivered solid work on Milestone 5 with multi-language support, 200-card monthly limit, and test ad implementation. He was also very responsive and helpful when we encountered issues on our end - always professional and patient. Looking forward to continuing with Milestone 5.5 for the remaining ad features and final store assets. Highly recommended!
