...workflow out of spreadsheets and into the cloud. The core of the job is to deliver a web-based platform hosted on Firebase, with data stored and transmitted securely. What the application must do • Let me spin up unlimited “companies” so each business keeps its records completely separate. • Provide simple Email-and-Password authentication for every user role. (If you think we should layer OAuth or 2FA later, keep the codebase ready for it.) • Offer a clean UI where I can create customers, assign them to groups, and then post two entry types—Payment or Journal Voucher. • For each entry I’ll input debit, credit and a narration; the system automatically stamps the exact date-time and shows a grey running balance right below tha...

I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests. Every user should have a rich profile (avatar, bio, follower count, etc.) that is visible inside and outside rooms. Access & security Sign-in must happen exclusively through Gmail-based email login, using Google OAuth so the flow stays familiar and frictionless. No phone or other social options are required at launch, though the architecture should leave room for them later.

Authentication must rely solely on social-media login (Google, Facebook, or similar). After a successful OAuth handshake, users arrive at a clean “Chats” page where they can search conversations, start a new chat, or open an existing one. Inside each chat, the user should be able to send and receive plain text messages instantly; additional media types will be handled in later phases, so keep the data model flexible.

I have a Vue.js-based web application that now needs a solid identity layer. My goal is to wire both Okta and Auth0 into the project so users can sign in seamlessly, with room to enable SSO and MFA as the platform grows. Everything should feel native inside the existing Vue front-end and stay fully standards-compliant (OAuth 2.0 / OIDC). Here is what the work boils down to: • Configure Okta and Auth0 tenants, create the necessary applications, and supply ready-to-use client IDs, secrets, and callback URLs. • Drop authentication flows into my Vue codebase—login, logout, token refresh, and protected routes—using the official SDKs where possible. • Expose a clean method for switching between providers (Okta ↔ Auth0) so I can A/B test them during ro...

...providers—Okta and Auth0—to harden security and simplify user management. Here is what I need from you, an engineer who has done this before with real traffic: • User authentication configuration in both Okta and Auth0, mapped cleanly to our existing user tables and session logic. • Full single sign-on so customers can move between our companion apps without logging in again. • Secure API token flow (OAuth 2.0 / OIDC) that protects our REST endpoints and fits our current role-based permissions scheme. The application is built as a responsive web app (React + Node). I will give you repo access, an environment file, and Postman collections so you can test end-to-end. Acceptance will be based on: 1. New users can register and log in through either ...

I’m running a PHP application purchased from CodeCanyon and need two focused improvements. 1. Social sign-in Right now the script only supports its native username/password flow. I want to integrate OAuth so users can log in with Google, Facebook, Instagram and Outlook. After authentication the script must create or link the local account seamlessly and respect the existing role / plan structure. 2. Plan-change behaviour When a free user upgrades to any paid plan, every QR code they created while on the free tier must automatically flip to “inactive”. The user should see a simple toggle or button beside each code and be able to reactivate them individually; no re-creation should be necessary. Database entries, statistics and existing short links must stay int...

The exact CRM will be confirmed on our first call; expect one of the mainstream options such as Salesforce, HubSpot, or Zoho CRM. Whichever it is, the work will revolve around their public REST APIs, webhooks, and OAuth-based authentication. You should already feel comfortable mapping fields, handling rate limits, and writing lightweight error handling so that contacts, deals, and a handful of custom objects sync reliably both ways.

I have a Replit workspace running a small Node.js app with a PostgreSQL database, and I need it to connect to Xero via OAuth 2.0, pull my invoice data, and render the results in a clean, browser-based dashboard. Here is the flow I’m after. When a user authorises through Xero OAuth 2.0, the app should store the access/refresh tokens securely in Postgres. On subsequent visits the server must refresh tokens automatically, query the Invoices endpoint, and pass the latest invoice records to the front-end. The dashboard only needs basic filtering (status, date range) and sortable columns, but it must be responsive and fast. Fetching and displaying data is the sole purpose—no record creation or updates for now. You’ll be working entirely inside Replit, so knowled...
