NFC Multi-Platform App
Shuja was a pleasure to work with and delivered a large quantity of work at a fair price. Communication was excellent and he always made sure the job was completed to a high standard. Shuja fixed small bugs very quickly(usually same day!) and was always available for extra work for further upgrades I requested.
