Improve speed and remove error

Budget: 2000 UAH Deadline: 1 day

Anton, I see two critical points here: speed and failure in the cart/checkout. First, I will check what exactly is slowing down the pages — heavy scripts, images, cache, or server requests — and remove the unnecessary without risking functionality. At the same time, I will find the cause of the error in the order processing and fix it at the level of logic or integrations. I have experience with e-commerce, so I work not "blindly," but based on symptoms and causes. I am ready to quickly get started and provide a clear result.

Hello. I have extensive experience in website optimization. I am ready for collaboration.

I will conduct a comprehensive technical optimization of the critical rendering path (CRP) for instant loading and resolve the script conflict that blocks order processing.

Please let me know if the checkout error is recorded in the server's error.log as a 500 (Internal Server Error), or if it is a JS failure that only appears in the browser console after clicking the button? This will determine whether we will "treat" the server request handler or fix the library conflicts on the frontend that prevent the client from completing the payment.

I am ready to start diagnosing the logs and analyzing the scripts immediately after gaining access. 🤝

Please let us know what the website is built on (WordPress/Shopify/custom) and if you can send the URL and simple steps after which the error occurs during checkout? We will also need access to the admin panel/hosting or at least a screenshot of the error and information about the latest changes/plugins.

We have 4 years of experience with JS (React, HTML/CSS) and Python (Flask/Django). We regularly speed up websites: image optimization, minification, lazy-load, critical CSS, caching/CDN. Experience with marketplaces: we have fixed checkout errors (cart, payment, validation), raised Lighthouse scores to 90+.

We are ready to start with a quick audit, then a plan and corrections. Write in the chat to agree on access and get started right away.
