At Capgemini, I built two React Native Windows retail solutions: a modernization of a legacy POS system and a greenfield Self-Checkout initiative. They support multi-locale layouts and were deployed across 1,250+ stores in the GCC/MENA region, processing 40+ million transactions.

I also developed mobile apps across ecommerce, healthcare, and pharmaceutical work, using React Native, Swift, and Objective-C. Earlier, I developed iPad POS and Mac OS applications, including work on iSCSI migration and HFS+ compatibility.
