I’m creating a personal Android application that lets users post freelance jobs from their phones. The core I need right now is a smooth job-posting flow backed by a secure login system, so every action happens inside an authenticated session. Here’s what the first release must cover: • Email- and password-based sign-up / sign-in (Google or Facebook OAuth would be a nice bonus, but ordinary credentials are enough to start). • Clean “Post a Job” screen where users enter title, description, budget range and optionally attach images or files. • A simple home feed that lists all posted jobs in reverse-chronological order, tappable to view full details. • Firebase (or any comparable BaaS you prefer) handling auth, storage and real-time update...
The Apple Sign-in flow on is coded already, yet the app still refuses to authenticate once it reaches Apple’s servers. I’m certain the problem sits in the .env file—values are probably missing, mistyped, or mismatched with what Apple expects—so I need an experienced developer to step in and straighten it out. Here’s what I know so far • The login makes it to Apple but fails to authenticate. • I’m not seeing a clear error on screen, so you may need to surface or trace the response. • I haven’t double-checked that the client ID, client secret, redirect URI, and related keys line up with my Apple Developer settings. What I need from you 1. Inspect the existing codebase and .env file. 2. Cross-verify every Apple credential i...
I’m setting up centralized authentication on our Kong API gateway and want to enable the built-in JWT plugin. The goal is straightforward: every request to our protected routes should be validated through Kong’s native JWT support, then routed onward to our existing internal microservices once the token checks out. Here’s the current state and what I need from you: • Kong is already running in our staging Kubernetes cluster, fronting several REST services. • No auth is active yet—routes are open. • I have a list of internal consumer apps that will need their own key pairs or shared secrets. • Our services already issue JWTs; payload and signing algorithm follow the standard RFC, so we only need Kong configured to recognise and verify them...

I need a clean, well-documented integration that lets my in-house system talk to the eBay Inventory/Trading APIs so I can manage physical product listings without touching the web interface. The integration must cover two core actions only: • Add new listings (SKU, images, price, quantity, item specifics, shipping profile, etc.) • Update existing listings (price, quantity, description and any revised specifics) No delete or end-item logic is required at this stage. Once finished I expect: – OAuth application keys properly created and stored. – A lightweight script or micro-service (PHP, Node.js or Python—choose what you’re strongest with) that wraps the required endpoints. – Clear README explaining setup, environment variables and sample calls...
I need a developer to wire up my existing eBay developer account so I can: • List brand-new products automatically • Pull sales data in real time for reporting • Sync my on-hand inventory with what is live on eBay You are free to choose the most efficient stack—whether you prefer the official eBay REST SDK, direct REST calls, or a lightweight wrapper—but the end result must authenticate through my keys, handle OAuth refresh, and expose clean functions or endpoints for the three actions above. Please build with clear, well-commented code and provide brief setup notes so I can drop new credentials into a config file and run. Once delivered, I’ll test by listing a sample item, fetching its sale (via sandbox or live), and updating stock; everything shoul...
