Hello! I have served many similar projects; to proceed further, please open the chatbox so we can discuss and proceed. I read through your issue, and this looks like a typical case where things are already built but not behaving properly in production. I’ve dealt with similar Node setups on AWS where the real problem isn’t writing code, it’s figuring out what’s actually breaking under the hood. I’m comfortable working directly on EC2, checking logs, fixing API flows, and sorting out auth issues like tokens, headers, cookies, etc. Login and account creation bugs usually come down to small logic or timing issues, so I’d start by tracing requests and fixing that flow first. After that, I’d clean up the API sequence and then look at performance, memory usage, and anything slowing the system down. I don’t rebuild things unnecessarily; I focus on fixing what’s already there and making it stable. One thing I’d like to check: are you using any process manager like PM2 or just running Node directly on the server? We can start quickly once I get access. Best regards, Jasmin

Hi, thank you for posting this good task! It sounds like this is a backend automation/debugging project, not a rebuild - and that’s exactly where careful Node.js work matters most. Your main issue isn’t just bugs, it’s unreliable logic in a live AWS environment where login, account creation, and API sequencing all need to work consistently under real server conditions. I’d approach this directly on your EC2 setup: first trace the current request flow end-to-end, then isolate where authentication, token/cookie handling, headers, or sequence timing are breaking. From there, I’d fix the logic, clean up failure handling, and optimize the Node.js processes so the system runs faster and more reliably without introducing new instability. My focus would be: - login and account creation debugging - correcting API call order and auth flow - fixing bad responses / silent failures - improving server-side performance, logging, and stability - making the existing code easier to maintain going forward I’m comfortable working inside deployed AWS environments, debugging live Node.js systems, and improving existing codebases rather than starting from scratch. For automation-heavy systems, small mistakes in request timing, session persistence, or retry logic usually cause the biggest failures-I know how to find and fix those quickly. If you want someone who can step into the current AWS setup, understand the logic fast, and get this stable, I’m ready to start. Best regards, Diah

Hi, As per my understanding: You've got a Node.js automation system on AWS EC2 that's deployed but buggy—login issues, account creation flow problems, wonky API sequences with headers/tokens/cookies, plus needs speed/stability tweaks on the live server. Implementation approach: - Quick code review on your AWS env to pinpoint login/account bugs. - Refactor API logic for proper sequencing/auth handling. - Optimize Node loops/requests for perf gains. A couple questions: 1) Main error logs from recent failures? 2) Specific APIs involved? I'll share my portfolio on your first message. Confident we can nail this post-chat. Cheers

Hello, I’ve reviewed your Node.js automation system issues, especially the broken login flow and unstable API call handling on your EC2 setup, and I’m confident I can stabilize and optimize the deployment directly in your AWS environment. I’ve previously debugged and refactored high‑frequency Node.js services on EC2, resolving authentication failures and reducing API error rates by over 40%. The real challenge here is not just fixing broken endpoints but tracing how tokens, cookies, and headers propagate through the existing logic under live load. Many systems fail because updates are made locally without understanding how AWS runtime conditions affect execution order and state. I’ll profile your current system, repair the login and account creation flows, correct API sequencing, and rewrite inefficient sections to improve speed and reliability. I’ll also test behaviour directly on EC2 to ensure fixes match the production environment. Before starting, I need access details and clarity on your current logging level so I can trace the issues efficiently. I can begin immediately. Best regards, John allen-.
