Hi, You’re not dealing with a big rewrite here , the real issue is a few broken links between price logic, API responses, and React state. I can trace the cart total formatting problem, repair the misconfigured backend routes, and clean up the duplicate rendering caused by the current useEffect/state flow while keeping your structure intact. I’ve fixed similar React + API issues in demo and production-style ecommerce builds, and I’ll work methodically through the frontend and backend together so the app becomes stable, predictable, and easy to verify. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can start immediately and aim to have the core fixes reviewed within your four-hour window. Could you share the repo access and confirm whether the API is plain REST or connected to any auth/middleware? Could you share the repo access and confirm whether the API is plain REST or connected to any auth/middleware? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, I can jump into your small eCommerce demo application and fix the broken frontend and backend issues while keeping the existing project structure intact. I will review the cart calculation logic, correct the price formatting or type conversion issue, fix the misconfigured backend API routes, and resolve the frontend useEffect or state management bug that is causing duplicate or incorrect rendering. I will also test the full flow after the fixes to confirm the cart total is accurate, API endpoints respond correctly, and the browser console is clean. Since this is an urgent debugging task, I can work directly from the provided codebase, identify the root causes quickly, and deliver a concise summary of what was fixed. If the project is small as described, completing this within four hours is realistic. Best, Justin

This sounds like a typical partially-wired eCommerce demo where a few small mismatches across frontend and backend end up breaking the flow. I’d start by reproducing the cart issue and inspecting how price values move through the system, since these bugs are usually type-related (strings vs numbers, formatting leaking into calculations, or floating point rounding). On the backend side I’d verify each route response shape and status handling, especially if Express/PHP routing is inconsistently returning data. Then I’d move to the frontend and trace the useEffect/state flow to catch any dependency issues causing duplicate renders or repeated fetches. I’ve seen similar state sync problems while working on a Vue/Nuxt setup at Bubbl where effect-like watchers kept re-triggering API calls. Once stable, I’d centralize cart total logic into a single utility so UI and API don’t diverge again. I’ll keep console clean and ensure consistent data flow end to end.

@mickeysz

Hello From my perspective, issues like incorrect cart totals often come from type mismatch or inconsistent price formatting between frontend and backend, while duplicate rendering usually happens due to uncontrolled useEffect execution or improper state updates. Misconfigured API routes typically result in failed requests or unexpected payload structures that break UI rendering. Compared to similar debugging tasks, the key focus here is not restructuring the application but quickly isolating root causes and applying minimal safe fixes while preserving the existing codebase and functionality. In terms of experience, I have worked on Node and Angular based applications where I handled similar issues such as duplicate API calls causing repeated renders, cart miscalculations due to string vs number handling, and REST endpoints returning incorrect responses. In one case, fixing redundant state triggers in a checkout flow reduced duplicated UI updates and stabilized the full purchase process during testing. My plan is to reproduce the issues locally, inspect network and console logs, trace frontend state behavior, validate backend API responses, and apply targeted fixes to cart logic, routing, and useEffect dependencies without altering the overall structure. Thank you.

Hi, this sounds like a straightforward debug fix, and I can help get it stable quickly. The issues you listed are the kind I handle often: cart math going wrong because of type/format problems, API routes misbehaving, and React state updates causing duplicate renders or stale data. I’d approach it by tracing the broken flow end to end, fixing the Node.js and JavaScript problems at the source, and then testing the full checkout/cart path so the demo behaves cleanly. I’m comfortable jumping into existing code without changing the structure more than needed. I’ll keep the frontend and backend aligned, clean up the API Development issues, and make sure the console stays free of errors. Since you want this done fast, I’d focus on the highest-impact fixes first and move through the app carefully so nothing else breaks. If you want, I can start right away. Osama

@cliftonc20

Hello, this reads like a small full-stack bug pass where the real work is tracing a few coupled data-flow failures without disturbing the existing structure. The real engineering risk is hidden state and contract drift between the API responses, numeric coercion, and frontend render lifecycle, because that is what usually turns a “simple fix” into repeated regressions. I’ve built and debugged production web systems with this same shape: backend routes, client-side state, and data integrity issues that surface as duplicate renders or incorrect totals. The Node.js/API side of this is familiar territory. The closest match is Dent-Cloud, where I worked across backend APIs and frontend data flows, including cases where response shape and client assumptions had to be tightened without rewriting the app. DocIntel AI is also relevant from the standpoint of keeping frontend and backend contracts clean under an existing architecture. I usually approach this by isolating three layers first: value normalization, API contract verification, and render/state triggers. That makes it possible to fix the total calculation, route failures, and duplicate rendering with minimal surface-area changes. If useful, I can start by mapping the failing request/response paths and identifying where the cart values or render cycle diverge. Clifton
