Hello. I need a team (or a single developer if you can complete all required work.) to build a cash back website. I would prefer an open-sourced CMS with easy access for admins for purchase tracking while maintaining excellent security. I don't have many specific requirements now but the main points will be:
1. Easy, fast navigations and reliable system for visitors and easy management for admins
2. Real-time accurate tracking (If merchants/affiliates support that)
3. Strong privacy protection on registered users' information, including encrypted storage of any possible financial information.
