About Cumaali Sentuna
International operations and retail leader with 20+ years across jewelry retail, wholesale, supply chain and e-commerce in the United States, the Gulf and Türkiye.
I build the commercial systems that move product across borders: store networks, wholesale channels, procurement and digital commerce. At Atasay I helped open and operate 16 international jewelry stores (UAE 10, Iraq 4, Qatar 1, Istanbul Airport 1), supported overseas store performance as Overseas Stores Executive and Operations Supervisor, and earlier coordinated fine jewelry manufacturing and wholesale in the United States for brands and retailers including QVC, HSN and Walmart. I also led JOU brand development in Türkiye and later digital and operational infrastructure work including SAP, RFID and inventory control.
At Qatris Jewellery LLC in Houston I served as International Operations Manager (2023–2025), building US wholesale operations and a network of 120 retail clients across multiple states while coordinating custom manufacturing in Türkiye and end-to-end commercial logistics. At Lizay Diamond (2022–2023) I managed gold procurement and supply for a nationwide retail network. At Sulis Gold (2025–2026) I led T-Soft e-commerce operations, product content, online merchandising, inventory processes and digital marketing coordination.
I am the author of KILL THE BORDERS: Global Marketing Strategies for a Borderless World. EU citizen, based in İstanbul, open to relocation, and focused on international retail / wholesale roles where operations and B2B & B2C sales meet.
