CareerConnect’s checkout flow is already wired to the PayPal REST APIs, but the live environment still throws payment-confirmation errors and occasionally rejects the stored API credentials. Everything runs on a Node.js backend hosted on an EC2 instance, so I need an experienced developer to step in, audit the current code, and get the integration production-ready. Here is what I expect you to tackle: • Review the existing PayPal REST setup (client ID, secret and webhook ID are in place) and pinpoint why live transactions fail to confirm. • Re-configure or regenerate credentials if necessary and update the Node.js environment variables securely. • Create or adjust the webhook in my PayPal dashboard, then validate the callback URL on EC2 so that real-time payment ...

My finance backlog lives inside a proprietary project-management portal and needs disciplined, daily upkeep. All financial data from multiple bank feeds must be entered, normalized, and matched so the running balance aligns with our statements; any exceptions have to be flagged and cleared. After each entry cycle, I also rely on you to raise invoices from the same portal, chase unpaid ones, and mark them as settled once payment hits the account. The platform lets me pull real-time dashboards, but only if the data is clean. That means you will: • Enter every transaction promptly, assigning the correct cost codes and notes • Reconcile portal balances against our monthly bank statements until they match to the cent • Generate and export summary and detail reports that...

Shopify Plus Developer (Remote – Indonesia Preferred) I’m launching a brand-new Shopify Plus store for our Australian bathroom-ware brand and need a seasoned developer who can take the project from first commit through ongoing maintenance. The storefront must serve both retail customers and trade partners, so you’ll be configuring B2B trade accounts with features such as custom pricing tiers, seamless re-ordering and automated invoicing. From day one the site has to speak to our warehouse team: all orders will flow into CartonCloud, and pick-and-pack will be completely paperless. If you have also touched Cin7 or Unleashed, that flexibility will be a bonus for future phases, but CartonCloud is the system we’ll integrate first. You’ll work on: theme devel...

I want to replace a patchwork of spreadsheets and email threads with one streamlined process that automatically produces accurate, professional invoices the moment a purchase order is fulfilled.

I need a quick, real-money check of my Shopify store’s PayPal integration. You will place a symbolic order for US $0.75 and walk through to the “Payment confirmed” page so I can be sure the hand-off and return flow are working. Here’s the flow I expect: from the storefront checkout you choose PayPal, complete the payment, and land back on the Shopify confirmation screen.

I’m building a full-stack web platform that sells access to an in-house large-language-model (LLM). The site’s core is e-commerce, but instead of one-off product sales I need subscription services with clear, tiered plans (think “Starter”, “Pro”, “Enterprise”). Each tier will unlock a different usage quota to the model, so the paywall must integrate tightly with the API gateway that fronts the LLM. Scope of work • Design a responsive customer-facing site where visitors can learn about the model, compare tiers, and sign up. • Implement secure user authentication, payment processing, and a dashboard where subscribers can view remaining tokens, upgrade/downgrade, or cancel. • Build the back-end that meters requests to the L...

1. Overview This project covers the design and delivery of an all-in-one car rental and fleet management system: a single system that handles reservations, fleet, payments, customer communication, and reporting for a rental operation. The goal is to replace the usual patchwork of spreadsheets, paper agreements, and disconnected booking tools with one connected workflow that runs from a customer's first booking through to the final invoice. The platform is built for car and van rental as its core use case but is structured to flex into adjacent rental markets — motorbikes, boats, equipment, and long-term leasing — through configuration rather than rebuild. ## 2. Objectives - Let customers book and pay 24/7 through a branded online channel, without a phone call or a deve...

Our training organisation runs in-person workshops for corporate executives and now needs a high-end, clean, responsive website that moves all enrolment steps online. The site must let visitors submit an initial Expression of Interest, progress to a bookings page, register as users (registration is mandatory for every attendee), and then complete payment on the spot. Core flow 1. Visitor lands on an EOI form, submits, and receives an automated acknowledgement. 2. From that confirmation, the visitor is directed to choose a workshop date on the bookings page. 3. They create a user account or sign in—no guest checkout. 4. Payment is completed through either credit/debit card or direct bank transfer; the system should record payment status and trigger the appropriate email rec...

I’m building a new marketplace on Sharetribe and need someone who lives and breathes the platform. The first milestone is to create custom listing fields and powerful search filters so buyers can find exactly what they need in a few clicks.

What I’ll look for when I review your proposal: • How many Sharetribe marketplaces you have taken live, with links I can test today • Your exact role on those projects (solo developer, tech lead, etc.) and how many years you’ve worked with Sharetribe • A ballpark timeline to get these customisations into production and your estimate...

I need a clean, fast-loading website that lets me sell digital products—specifically elektron kitoblar va hujjatlar—to my audience.

I need a developer who can connect my existing PHP site to a reliable payment gateway. The goal is to give customers a smooth, secure checkout experience from start to finish. I am currently leaning toward well-known services such as PayPal, Stripe, or Square, but I am open to your recommendation if another platform would suit the codebase better. You will be working with a live production environment, so clean, well-documented code and clear hand-off notes are essential. If you have prior experience handling tokenization, secure storage of credentials, and sandbox/live environment switching in PHP, that will help us move quickly. Once the integration is complete I’ll run a few test transactions; as long as those settle correctly and the confirmation callbacks reach my applicat...
