You will get Amazon Product Upload Automation using Selling Partner API (SP API)
Project details
Automate your Amazon product uploads and updates with a powerful backend solution built using the Amazon Selling Partner API (SP API). This project is designed for Amazon Seller Central and Vendor Central users who want to save time, reduce manual work, and ensure their product data stays perfectly synced.
I’ll develop a secure, scalable API (using Laravel or FastAPI) that connects directly to Amazon’s SP API — handling Feeds, Listings, and Catalog Items seamlessly. Your system will automatically upload product data such as SKUs, titles, prices, descriptions, images, and quantities with real-time tracking of upload statuses.
Key features include automated feed submission, error and retry handling, token refresh management, and multi-account support. You’ll also receive detailed logs, monitoring tools, and integration support for your existing app or platform.
This solution cuts upload time by up to 90%, improves data accuracy, and ensures hassle-free synchronization for thousands of SKUs. Ideal for growing eCommerce businesses, Amazon sellers, or agencies managing multiple stores.

Build POS For Mobile Shops
I started working with Dayan in August 2023 under the same contract. Initially, he was hired for a different project, which unfortunately had to be closed midway. However, after observing his skills, dedication, and work quality, we decided to continue the contract and shift him to another project—our School ERP software.
Dayan played a key role in developing multiple important modules of the ERP system. He consistently provided valuable suggestions at critical stages of development. Whenever there was a need to adopt new technologies to enhance the product, he took the initiative to study them and quickly implemented effective solutions, even if the technology was new to him. On several occasions, he also recommended better and more scalable technology choices to improve overall system performance.
In terms of communication and availability, Dayan is extremely responsive and reliable. He does not work by watching the clock and has always been available when required. If he was ever unavailable, he informed us well in advance, demonstrating strong professionalism.
He consistently met deadlines as long as requirements remained unchanged. His coding approach is ethical and professional—he focuses on writing clean, original code rather than relying on copy-paste or AI-generated solutions. If you have a clear vision and can communicate your requirements effectively, he will deliver exactly what you expect.
I highly recommend Dayan without any hesitation. He is a dependable, skilled, and committed professional, and anyone hiring him can do so with complete confidence.

→ Multivendor marketplaces & e-commerce platforms
→ API integrations, automation & backend systems

Recent AI projects shipped:

→ E-commerce AI Assistant — trained on a client's product catalog to help customers discover books and accessories through a conversational interface.
→ Carity AI (Car Dealer Chatbot) — worked as backend engineer on a Canada-based AI assistant that powers 60,000+ AI conversations per month, helping dealerships automatically qualify used car inventory.
Also delivered:
