We used React to build a dynamic, responsive interface for live polls and questions, while Express and MongoDB power the backend to store and process responses in real time. Hosts can create single or multiple-choice polls on the fly, and participants can submit answers or questions without leaving the meeting. Results appear instantly, giving presenters immediate insight and control. This add-on has become a go-to tool for educators, team leads, and event hosts who want deeper engagement with zero friction.

Using React for the frontend and Express with MongoDB for the backend, we developed an intuitive tool that automatically tracks attendance and allows for easy, structured note-taking during the call. Attendees can check themselves in with a single click, and hosts can assign notes or jot down highlights for each participant. Notes and attendance logs are compiled and made shareable through a link, or exported for later use. The result is a tool that improves productivity, documentation, and meeting clarity all without leaving Google Meet.

We built the Collaborative Whiteboard using React on the frontend, with a lightweight and responsive UI. The backend architecture runs on Express and MongoDB, handling live session data and real-time user sync. To power the drawing experience, we integrated Excalidraw, an open-source drawing tool that gave us the flexibility to support anything from sticky notes to technical diagrams. The result is a robust, elegant whiteboarding solution that feels like a natural extension of Google Meet. It’s become a favorite for educators, product teams, and visual thinkers across the board.

We approached the project with a streamlined tech stack designed for speed, scalability, and seamless integration. On the frontend, we used Vite and React to build a fast, modular experience. By embedding Credibled’s existing web application inside an iframe, we ensured the add-on preserved their branding and UX, allowing users to interact with their reference-checking platform exactly as they would on the web.

For the backend, we created a Node.js + Express API, paired with MongoDB, to handle authentication, user sessions, and lead capture. This system allowed us to persist key data like user names and emails while remaining fully compatible with any CRM or analytics tools Credibled might choose to integrate down the line.

To support real-time communication between users and the embedded tool, we implemented WebSockets, enabling instant, lag-free interactions within the Google Meet interface. The end result is a high-performance, embedded solution that gives recruiters the power of Credibled’s platform right where they need it most inside the interview itself.

The Credibled Google Meet add-on is now live in the Google Workspace Marketplace, helping hiring teams streamline reference checks without ever leaving the call.
