Prior to joining Yugabyte in 2020, Walker held the position of Interim CTO at P27 Nordic Payments and served as the Enterprise Programme Director and Chief Architect of Global Enterprise Data Platforms at Worldpay, in London. In his previous roles, he implemented crucial systems for several high-profile organisations, including the Dutch National Police, Diageo, Network Rail, Turkcell and Telkom SA.

"David's extensive experience and expertise in the field make him an invaluable resource in driving innovation and growth. We are confident that this partnership between Obsidian Systems and Yugabyte will empower businesses in the region to scale and manage their data more effectively, while fostering stronger relationships between our companies,” says Van Staden.

During his visit, Walker will engage with Obsidian Systems clients and local businesses, discussing innovative solutions and best practices in database management. This collaboration between Yugabyte and Obsidian Systems showcases the commitment both companies have towards delivering cutting-edge technology solutions and supporting the growth of businesses in South Africa and beyond.
