    Playful Trading Card Website Build

    I’ve just launched my first trading-card game, “Dinosaur Deck,” under my new company, Fort of Toys, and I’m ready to give it a vibrant online home. The site has to feel as playful and colorful as the cards themselves while still guiding visitors smoothly to a purchase. Here’s the structure I have in mind. The landing page will highlight “Dinosaur Deck” up front, then tease the next releases—“Chemistry Compounds Deck,” “Space Deck,” “Periodic Table Deck,” and “Vedic Maths Deck.” Each of these needs its own section so I can swap in new artwork and copy as the designs finalize. For the product area I’m picturing a grid view filled with large, punchy images; when someone clicks a card deck, t...

    Stripe UPI + Wallets Integration

    I already accept card payments on my site; now I want to broaden the checkout so visitors can also pay with Stripe UPI first, and then Apple Pay, Google Pay and PayPal. You will receive my active Stripe account keys, so there is no account setup work—just the technical integration and any configuration changes inside the Stripe dashboard needed to switch on UPI and wallet payments. Recurring billing through Stripe UPI is essential because several subscription-based plans run on the platform. Once Stripe UPI is live and tested, we can move on to Apple Pay and Google Pay (using the standard Payment Request element or Stripe’s Web SDK) and finally wire up PayPal. Everything must run seamlessly inside the current Bubble workflows and respect my existing data structure, so no...

    I need a complete rideshare solution built from the ground up for both iOS and Android. The core flow is familiar—riders request, drivers accept, trips are tracked in real time—but there are a few extras that are non-negotiable: • Third-party booking: a user must be able to schedule and pay for a ride on someone else’s behalf. A common use case will be parents arranging rides for their children. • In-app texting: rider ↔ driver, plus system notifications, all stored for audit. • PayPal checkout: for now that is the only payment rail we’ll launch with, so make sure the integration is production-ready and PCI-compliant. • Centralised user store: one secure database that holds drivers, riders, and parents with clearly differentiated role...

    I need a fresh, fully-functional e-commerce site where I can showcase and sell physical products. The store should feel modern, load quickly on mobile, and make it effortless for customers to browse, add items to the cart, and check out.
