With over 12+ years of experience in Full-Stack development, particularly in React and Python, I can quickly identify and resolve these critical bugs. I’ve worked on numerous e-commerce projects, troubleshooting similar issues involving REST APIs and payment processing. I’m available to start immediately and can ensure the fixes are implemented and tested by the weekend. Let’s get your shop up and running smoothly! Please see our portfolio on this link : https://www.freelancer.com/u/webperfection123 Best Regards, Priyanka

@denisSolution

Hi, I’m Denis. I’ve worked on e-commerce systems where React frontends and Python backends needed tight integration for checkout, payments, and order processing. The issues you described with API mismatches and session-related failures are common when components aren’t properly aligned or when edge cases in data flow aren’t handled. I’ll start by reviewing the API contracts and the frontend/backend data handling to pinpoint where mismatches occur. Once the root causes are clear, I’ll fix the React-Python integration, stabilize the checkout flow, and ensure digital product delivery works reliably. Testing the full purchase journey will be the priority to confirm everything functions end-to-end. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

I’ll thoroughly test the complete flow from login → product purchase → payment → order processing → digital delivery, while ensuring existing functionality remains intact. Timeline: Within 2 days Availability: Immediate Experience: React, Python, REST APIs, databases, payments, authentication, and e-commerce debugging I can share relevant full-stack debugging examples upon request. Best regards, Muhammad Rizwan LA

@ranjika08

The main risk here is that the visible errors—missing data, failed checkout, broken delivery—may all come from one or two backend/API bottlenecks rather than separate bugs. In cases like this, patching symptoms wastes time, so I’d debug the request/response chain, payment flow, and session/auth handling first, then verify the full order path from cart to delivery. I’ve worked on React + Python troubleshooting for live web apps, including REST API inconsistencies, checkout/order failures, login/session conflicts, and database-linked issues inside existing systems. That kind of work is very different from building new screens, and it fits this brief well. A couple of points would help me hit your weekend deadline cleanly: - Which payment provider and digital delivery method are in use? - Have any recent code changes triggered these issues, or are they older unresolved bugs? - Do you want fixes only, or also a short summary of root causes after testing?

@shaktistanwar

Hi, I can start immediately and troubleshoot your existing React + Python e-commerce application, with the goal of restoring the complete customer purchase flow within your 2-day deadline. I understand the priority is not rebuilding the application, but identifying the root causes and fixing the existing frontend, backend, API and transaction issues. I can handle: React ↔ Python REST API debugging and integration fixes Incorrect/missing data and API response handling Checkout and payment processing failures Order creation and status workflow issues Digital product delivery problems Authentication, sessions and authorization issues Database/API consistency and error handling End-to-end purchase-flow testing Regression testing after fixes I’ll first reproduce the issues, trace requests from React → API → Python backend → database/payment → order/delivery, identify the root cause, and implement focused fixes without unnecessarily changing working functionality. I’m experienced with React, Python, REST APIs, databases, authentication and e-commerce workflows, and I’m comfortable working directly inside an existing codebase. Availability: Immediate Timeline: Within 2 days Budget: Can work within your stated range after reviewing the existing issues/codebase. I can share relevant full-stack debugging examples and start as soon as access is provided. Best regards, Shakti Tamnwar

@melikatfz

Hi there, It sounds like your e-commerce site is facing critical integration issues that could disrupt customer transactions and overall user experience. Left unresolved, these problems can lead to lost sales and customer dissatisfaction. With my extensive experience in both React and Python development, I can swiftly identify and fix these integration issues, ensuring a smooth customer journey from browsing to purchase. Here are my questions: What specific errors or messages are you seeing during the checkout process? Could you share any recent changes made to the codebase that might have triggered these issues? Let's discuss your project now!

@Joya1996

What you need fixed is the transaction chain itself—frontend data loading, backend/API communication, successful checkout, and the customer receiving the digital product without auth/session problems. In ecommerce systems, these bugs tend to be connected, so patching one screen without tracing the full flow usually leaves hidden failures behind. I’d debug this from the API layer outward, verify payloads and order states, then run full purchase-flow testing after the fixes. I’ve done similar repair work on React/Python applications where broken API mappings caused missing product data, checkout failed due to backend processing issues, and login/session conflicts blocked post-purchase access. Working inside an existing app and stabilizing it fast is very different from greenfield development, and that’s the kind of work I’m used to. A couple of details would help me target the first pass properly: - Is the digital product delivered instantly after payment, or only after a status change/webhook confirms the order? - Do you already know whether the checkout problem is frontend-side, backend-side, or still unconfirmed? - Is there a staging copy available for safe testing before changes go live?
