...The core job is to own feature development end-to-end: architecting clean Dart code, wiring up real-time data flow, refining UI components for multiple screen sizes, then shipping fully tested builds to the App Store and Google Play. The project already has a high-level product roadmap; you will turn that vision into production-ready widgets, state management (Bloc or Provider is fine), secure API integrations, and smooth animations. Regular collaboration with our designer and back-end team happens in Slack and Jira, with code reviews in Git. I release milestones every two weeks, and each sprint should close with: • A compiled iOS and Android build (TestFlight / internal track) • Source in our Git repo with clear commit history • Brief release notes and any m...
My production MERN app is throwing backend issues that I need resolved quickly. The most critical problems sit in the Node + Express layer: API endpoint failures and intermittent server errors, with the user-authentication route being the main culprit. What I need you to do • Trace the failing auth flow, locate the root cause (token handling, middleware, DB calls, etc.) and patch it. • Audit the rest of the backend for similar API glitches, cleaning up code where necessary. • Make sure every fix plays nicely with MongoDB queries and indexes. Please keep the code clean, well-commented, and push via Git so I can review commits. I’m aiming for a 3- to 5-day turnaround. The budget is set at roughly €20, but I’m flexible if unexpecte...
Plaid + Chase Connectivity Issue via API Plaid + Chase OAuth Integration — "Invalid Credentials" After Successful OAuth Flow The Problem: We have a production Plaid integration (Node.js/Express) that connects bank accounts via Plaid Link. American Express and Capital One connect and sync perfectly. Chase fails every time with "Username or password incorrect" AFTER the OAuth flow completes successfully. The Flow: 1. User clicks Connect Bank → Plaid Link opens 2. User selects Chase → Plaid fires OPEN_OAUTH event 3. User redirects to Chase's website and logs in successfully 4. Chase redirects back to our app with oauth_state_id 5. Plaid Link re-opens with receivedRedirectUri 6. Plaid shows "Username or password incorrect" — co...

...bug related to money transfers and now want someone to debug and fix problem happens when two or more transfers from the same source account run at the same time. Under concurrent load, the system sometimes allows the account to spend more money than it actually has (double‑spend). With normal, single requests everything appears to work fine: balance checks pass, transfers look correct, and the UI/API responses are OK. The bug only shows up with concurrent requests. 1. Expected behavior: • Balance checks should be safe even under concurrency. • If an account has a balance of 100 and two transfers of 70 run at the same time, at most one sho...
