Mobile App Backend/API Fixes

@masummsnr

Hi, Inconsistent API responses and tokens expiring too early are server-side issues I can fix without touching your front end. Early expiry usually traces to a mismatched expiry clock or refresh logic; flaky social login often comes from bad OAuth callbacks or token exchange. I'd start by reproducing the failing calls and auditing your auth middleware, then wire in the new third-party endpoints with real error handling. I've built and debugged Node.js REST APIs and Firebase auth flows over four years of mobile work, so live fixes are familiar ground. After, I'll add quick sanity tests and brief inline docs so future updates stay clean. I can have the priority auth and API issues stable in about 6 days. First step: share repo access and I'll map the failing endpoints and a fix order. Regards, Nurullah Al Masum

@vasylklymiu

I think starting with a thorough review of the existing backend and stabilizing the authentication flow will be the best approach to restore reliability and support future improvements. I am a full stack developer with experience debugging live applications and improving backend systems. I can quickly dive into the current codebase, fix inconsistent API behavior, integrate new endpoints, and strengthen authentication and user management flows. I pay close attention to error handling and code quality to ensure the system remains stable and easier to maintain going forward. My goal is not only to resolve the current issues but also to leave the backend cleaner and more predictable with clear inline documentation and basic sanity tests for future updates. We can discuss the details in chat. I look forward to working with you. Which backend technology is your server currently built with?

@hugog17

⭐Hi there Let's set interview schedule if you want discuss for ur project more detail . Your live app needs backend fixes that make API calls, auth, and user flows stable again without touching the mobile UI too much. Fixed similar Node.js backend issues for a React Native app where token expiry, social login, and reset email failures were causing daily user complaints, then reduced auth related support issues by 70 percent within 2 weeks. For ur app, the first step is checking failing API logs, token TTL logic, refresh flow, social provider callback, and password reset trigger path. After that, broken endpoints can be refactored with clear error handling, stable response format, and quick sanity tests so future updates dont break same flows again. Can also wire new third party endpoints cleanly with env config, retry logic, and brief inline docs. Time line : 5 days Total Budget : 12000 INR Are the current backend APIs built fully in Node.js, or is there also another service handling auth?

@manoval09

I need the **complete project description** to write a compelling proposal. The text cuts off at "holding i" — I'm missing the core details about what's actually broken on the server side. Can you paste the full project description? Once I have it, I'll generate a tight, technical proposal that: - Directly mirrors their specific pain point - Shows I understand their backend/API issues - Suggests a concrete first step - Follows Val's voice (no fluff, no self-intro, straight to solving their problem)
