React-Node E-Portal Integration Help

The e-commerce portal I have been building in React and Node.js is roughly 70 % complete. Most core screens render, the cart behaves, and the main APIs respond, yet day-to-day I still hit thorny integration glitches that stall progress. The pressing pain points are classic code-level hurdles: subtle API mis-wires, optimisation bottlenecks, and stubborn bugs that surface when the front-end and back-end shake hands.

I want an experienced solution architect to join me in real time—screen-sharing, pair-programming, or short focused calls—to troubleshoot and refactor whatever surface area proves weakest. It could be a React component leaking state, a Node.js controller that blocks the event loop, or a database query that refuses to index correctly; the hot spot changes as we advance. Flexibility across the stack is therefore essential.

What I’ll provide:
• Full source in a private repo
• Access to the staging server and Postman collections
• Clear, reproducible steps for each issue as it appears

What I need in return:
• Rapid diagnosis and fixes for integration bugs
• Practical, performance-minded refactors rather than academic theory
• Guidance that leaves the codebase cleaner so the remaining 30 % ships smoothly

Sessions can be scheduled around GMT+5:30 evenings, though I’m open to staggered time slots that keep momentum high. If collaborating hands-on to push a near-finished portal over the line sounds interesting, let’s get started.
