E-Commerce Site Development Help

I’m building an online store focused on selling digital products and want an experienced developer to move the project forward. The core storefront will sit on WordPress, yet I also expect custom functionality that may tap into standalone PHP or even .NET components, so a good grasp of all three will be useful. Here’s what I need: • Clean WordPress installation configured for e-commerce • A lightweight theme tailored to digital downloads, fully responsive • Payment gateway integration (credit cards and PayPal at minimum) • Secure, automated delivery of purchased files with license-key support • Clear admin workflows for adding new products, coupons, and reports • Basic on-page SEO and performance tuning so pages load fast • Documentation so I can maintain everything after hand-over Acceptance criteria: the site must process a test purchase end-to-end, email the buyer a protected download link, and store the order in the dashboard without errors. If you have experience blending WordPress with custom PHP or .NET pieces, please tell me which similar projects you’ve launched and how you secured digital assets. Let’s get this store live quickly and smoothly.
