Hello, I am looking for a Shopify developer for a custom sweepstakes / raffle website. Concept: Users will register on the website and purchase entry codes like a digital product. After purchase the user receives unique entry codes via email or SMS. Each week we will run a live draw and select winners from all entries. Main features needed: • user registration • purchase of entry packs • unique code generation • database to store entries • random winner selection system • admin dashboard to manage draws • integration with Shopify payments (Apple Pay, Google Pay, card) Important: The system must be scalable and secure. Please let me know: • if you have built similar systems • what technology you recommend • estimated timeline and cost Thank you.
