Fix E-Commerce Cart Checkout Sync

Looking for an Experienced Full-Stack Engineer I’m looking for an experienced full-stack engineer to help resolve a critical issue in my existing e-commerce project. The issue appears to involve the shopping cart and checkout workflow. Product quantities and prices may become inconsistent after certain user actions, and cart data may not always synchronize correctly between the frontend and backend. This could affect order calculations and the overall purchasing process. I need someone who can carefully review the existing codebase, identify the root cause, and implement a reliable fix. Experience with frontend and backend development, API integration, database management, and e-commerce systems is important. I’m looking for someone who takes debugging seriously, pays attention to detail, and can communicate clearly throughout the process. If you have relevant experience and are interested in discussing the project, please send me a DM with a brief introduction, your technical background, and examples of similar issues you’ve solved. Budget: USD 250–750
