...data efficiently, and delivers real-time dashboards my team can rely on every day. Here’s what the work looks like: • React will drive a responsive, component-based interface that feels fast on both desktop and mobile. • Node.js with (or a comparable framework you prefer) will power a secure REST or GraphQL API, built with clear layering and strong typing where appropriate. • MongoDB will serve as the primary data store; I need well-designed schemas, indexing strategies, and aggregation pipelines that keep queries lightning quick even as data grows. • Third-party integrations—think payment gateways, external data feeds, and modern authentication providers—will plug in seamlessly, each wrapped in clean modules so they’re easy t...

... so deep, hands-on experience across each layer is essential. Stack and tooling The current plan leans on Node.js for server logic, for rendering and routing, and MongoDb for data persistence. Everything should be wired together with clean, testable JavaScript/TypeScript, Git-based workflows, and familiar DevOps practices (CI/CD, containerisation, cloud hosting of your choice). Daily responsibilities • Craft responsive, interactive UIs that feel native on web and mobile. • Implement rock-solid user authentication and role-based access. • Build REST/GraphQL endpoints and integrate them with the MongoDb data model. • Optimise queries, indexes, and backups to keep data fast and safe. • Ship iterative features in weekly sprints, write te...

A working Hebrew (RTL) invoice and delivery note OCR verification system (FastAPI, React, MongoDB, Google Vision) runs today for one account. This project makes it multi-tenant. Scope: 1. Registration and login: customer record with several logins, administrator and customer roles, email verification, password reset, invitations, approval of new accounts, a minimal admin page. 2. Mandatory acceptance of terms of use and privacy policy at registration, recorded with time, IP and version; versioned Hebrew and English texts editable without code. 3. Complete data separation: every record carries its customer, every query filters on the server, migration with count checks, a leak test suite over every route. 4. Plans with monthly job and page limits, usage counters, enforced at upload....

I already have a MongoDB-Express-React-Node project running locally, but it’s only about halfway there. I need someone who can first read the existing codebase, grasp the current architecture, and then drive it to production quality. Frontend improvements are the top priority. I’m aiming to add several new features to the React interface while keeping the look and feel consistent with what’s there now. Along the way you’ll also connect the app to Firebase services already configured in the repo and wire up the planned chatbot modules. Once the missing pieces are in place, the final step is a clean deployment—preferably through a CI/CD flow—so the app is live, stable, and easy to update. Deliverables • Implement the agreed-upon React feat...
