Most endpoints accept/return JSON, and uploads are sent as multipart/form-data — your code must handle both cleanly and reliably. Deliverables: A small, reusable, well-typed API client layer (e.g., /lib/api or similar) using fetch or Axios Authentication integration (bearer tokens / OAuth details provided). Requests should be signed correctly and handled consistently across the app Example usage: at least one working flow for: data retrieval data submission login/session handling file upload (multipart/form-data) Robust error handling (including loading + failure states) and a short README explaining patterns so I can extend them Important constraints: ...

The project covers two linked assets—a marketing website and an interactive web application—built as a single, cohesive code-base. Everything must be modern, fully responsive, and branded with a clean, intuitive UI/UX. Tech stack is already set: Angular on the frontend and a Node.js (Express) backend. Expect secure, stateless authentication (JWT or OAuth, whichever you judge best), role-based access, and a well-structured REST API that can later expand to GraphQL if needed. Data will live in either MySQL, PostgreSQL, or MongoDB; I’m open to whichever you recommend once requirements are refined. Core functionality • Public-facing pages for visitors • A logged-in web app with real-time notifications • Separate admin dashboard for user, content, a...

...changes. Database maintenance — PostgreSQL schema tweaks, query optimisation, connection resilience (the app already has server-error vs session-expired detection). Mobile UI polish — The frontend runs inside Telegram's embedded WebView on iOS and Android. Dark mode, keyboard handling, safe-area insets, and touch target sizing all matter. Session & auth — The app uses custom session management (not OAuth). Sessions are passed via URL params, headers, and cookies for Telegram WebView compatibility. You should understand why all three channels exist. Minor features — CSV export, order filtering, product management, dashboard stats. Nothing greenfield — mostly extending what's already there. Codebase structure you should know: Backend: co...

Diagnose the cause, update the OAuth flow if necessary, and get users logging in with their Google accounts again without errors. • When customers save an address, the city field should persist and be visible in the admin panel. At the moment that value is lost; make sure it stores and displays every time. • Finally, the solution must run strictly as an app. If someone tries to...

Because we’re working with a combination of old and new code, part of the job will involve auditing what’s already there, refactoring where it makes sense, and documenting your changes clearly so maintenance stays straightforward. Clean, commented code, Git-based version control, and concise commit messages are expected. ...

I already have a Discogs seller account, a registered application, and the consumer key / secret. What I am missing is a clean OAuth workflow and a repeatable cURL command (run from macOS Terminal) that can automatically post a new marketplace listing when I supply a release ID and the other listing details. Here is what I need from you: • Walk me through the correct authentication choice. I currently issue token-based cURL calls, but I am open to OAuth 1.0a or OAuth 2.0 if that is the reliable path for the “add listing” endpoint. • Provide the exact sequence of cURL commands: initial request token call, user authorisation, access token exchange (if applicable), and finally the POST call that creates the listing. • Document every step i...

I need a small-scale community-focused website that offers two sign-in options: Google OAuth (Gmail) and a classic email-and-password flow. The primary goal is community engagement, so once users are inside they must be able to create a profile, edit basic details, and exchange direct messages with each other. No e-commerce, no complex forums—just a clean, responsive space for members to connect. A lightweight tech stack is fine as long as it is secure and quick to deploy; React or Vue on the front end and Node, Django, or Laravel on the back end would all work if OAuth and secure password storage are implemented correctly. Mobile-friendly layout is required, and I’d like the initial build hosted on a standard cloud service (AWS, Heroku, Vercel, or similar) so I ...

This includes product setup, workflow tweaks, invoicing logic and whatever Stripe or Braintree hooks are required inside Bubble. In parallel, every task created in the CRM has to appear automatically in Google Calendar for the assigned user. I already have a Google account ready; what I need from you is the full OAuth handshake, event-creation workflow and a way to keep edits in sync both ways so users always see the latest due date. Finally, a handful of buttons and on-screen actions need to be relabelled or repurposed. These are minor UI changes but they sit on top of critical workflows, so attention to existing database structure and conditionals is a must. I will provide: • Curre...
