I need two specific, high-priority modules built and integrated into my existing Supabase architecture: 1. Automated Payment & Vendor Splits (Stripe Connect) Implement Stripe Connect (Express or Standard) to handle multi-sided transactions. Automate a 40/60 profit split (40% Platform / 60% Creator) at the point of sale. Configure automated onboarding flows for student "vendors" (KYC/KYB). 2. Dynamic DRM & Asset Security (The "Vault" Security) Implement Dynamic PDF Watermarking: Every file must be stamped with the Buyer’s Name, Email, and IP Address at the moment of download. Access Control: Ensure files are never directly accessible via a public URL; use Supabase Row Level Security (RLS) and Signed URLs to protect assets. Session Locking: Prevent a...

I’m looking for an Australia-based freelancer who already has an active ABN and knows the local onboarding requirements for Square, MyZeller, Stripe and any other tap-to-pay service. Square will be the first cab off the rank, but I’ll ask you to mirror the same setup across MyZeller and Stripe so I can accept both credit/debit cards in person and online transactions through my site. What I need from you is straightforward: help me open and verify the merchant accounts, connect the right bank details, fine-tune fee settings, and run a few live test sales so I’m sure payouts land where they should. If you’ve handled PCI compliance checks, GST mapping or daily settlement reconciliation before, that’s a big plus and will speed things up. Deliverables • Fu...

I’m ready to build a full-featured e-commerce web application and need a developer who can take the idea from concept to deployment. The core goal is to deliver a fast, secure online store that works flawlessly on desktop and mobile browsers. What I already know: this is a software-development job, not marketing or design in isolation, and the deliverable must be a web application, not a mobile or desktop installable. Scope of work • Plan and propose the tech stack that best balances performance, scalability, and ease of maintenance. Popular choices like React or Vue on the front end and Node, Django, Laravel, or similar on the back end are all on the table—convince me why yours is the right fit. • Design a clean, intuitive UI/UX with responsive layouts. &...

I want to launch a straightforward e-commerce site focused on selling my products and services online. The key requirement is a smooth, secure payment-gateway integration that lets customers pay without friction. Here is what I have in mind: • A clean, responsive storefront where I can showcase items, set prices, upload photos, and write descriptions. • A reliable payment solution (Stripe, PayPal, Razorpay, or a comparable gateway) fully configured, tested, and ready for live transactions. • An intuitive admin dashboard so I can add or edit products, track orders, and view basic sales reports—no coding knowledge on my end should be necessary. • Standard e-commerce essentials such as user-friendly navigation, cart functionality, order confirmation emails...

I have a production-ready mobile application that runs on both iOS and Android, but a handful of functionality bugs are undermining the user experience. I need those issues tracked down and resolved first, then I want to integrate Stripe and Apple Pay so users can complete in-app purchases seamlessly. Once everything passes review, the final step is publishing the updated builds to Google Play and the App Store. You will receive the full source code, existing build files, and store-listing credentials. Please test thoroughly on real devices, confirm that payments process in sandbox and live modes, and handle any store-side compliance tweaks that appear during submission. Deliverables • Bug-free iOS & Android builds • Fully working Stripe and Apple Pay flows (sandbox + l...

The site I have in mind revolves around one clear objective: secure, high-quality video storage and playback. Every clip will be sold individually, so the flow must guide a visitor from preview to one-time payment and then straight into their personal viewing area. After purchase, members log in to stream their content as often as they like, yet no subscription model or recurring fee should appear anywhere in the journey. A clean dashboard is important on my side too. I need to upload new teaching videos, set the single-purchase price, and monitor sales without digging through code. If you already have experience integrating payment gateways such as Stripe or PayPal, handling protected streaming (AWS S3 + CloudFront, Vimeo OTT, or any comparable stack), and building member authentication ...

FREELANCE DEVELOPER NEEDED – STABILIZE & IMPROVE REACT NATIVE MARKETPLACE APP (EXPO + SUPABASE + STRIPE) PROJECT OVERVIEW I am developing a peer-to-peer rental marketplace mobile application where users can list items for rent and others can book them. The concept is similar to platforms like Airbnb or Fat Llama, but focused on renting physical items between users. The application is already built and functional. The current priority is stabilizing and refining the existing system, improving reliability and UI consistency before expanding into additional features. This project is NOT about building an app from scratch. The core product already exists. The main goal now is to strengthen the existing architecture, improve stability, and polish the user experience so the platfor...

Our existing subscription platform (React + Express on Replit with Supabase) needs two tightly-scoped automations completed and deployed. Payment flow (target 1–2 days) • At sign-up, Stripe takes the first payment, then a GoCardless Direct Debit is created for recurring monthly charges. • Webhooks must reliably update each client’s status and next-billing date inside Supabase. Domain go-live (target 1 day) • As soon as the initial payment clears, a Cloudflare API call should register the client’s chosen domain, apply the required DNS records, and provision SSL automatically. • A confirmation email is sent to the client once DNS and SSL validation succeed. Codebase & tools: Node.js, Replit, Supabase, Stripe, GoCardless, Cloudflare. Ple...

Cloud storage focus – Finalise Cloudflare R2 uploads & signed URLs – Google Drive API integration for master e-book assets and b...

Auf meiner Website können Personen mit Diabetes Zoom-Webinare buchen. Die Buchung läuft bereits über Calendly; jetzt soll die Zahlung direkt im Buchungsschritt erfolgen. Ich habe sowohl ein Calendly- als auch ein Stripe-Konto angelegt. Deine Aufgabe ist es, beide Konten so einzurichten, dass möglichst viele Zahlungsarten automatisch angezeigt und genutzt werden können – konkret Kreditkarte, Bankeinzug, Klarna, Überweisung und PayPal. Der Prozess darf ausschließlich auf Deutsch erscheinen; Mehrsprachigkeit ist nicht nötig. So stelle ich mir die Zusammenarbeit vor: • Du verbindest Dich per Remote-Session (TeamViewer, Zoom o. Ä.) auf meinen Rechner und richtest alles gemeinsam mit mir ein. • Du aktivierst in Stripe die e...
