Backend Developer for Graph-Based Digital Knowledge Platform
The Project: We are looking for a developer to create the foundations for a graph based knowledge platform. The platform will contain thousands of pages of information which all connect to each other creating a map allowing users to easily navigate between related pages. The backend functionality will be similar to how Roam Research and Obsidian work. They both create notes which show as nodes in a graph, as well as the connections between them. We are creating a close-ended digital knowledge garden, meaning users can explore the information already in there but cannot add their own. The scope of this project is to implement the first phase which involves building the backend of the platform to facilitate the features. This will be our own version of a Roam or Obsidian style platform. We will then look to add further functions at a later stage. There are three main planned aspects to the platform: - Pages are where the information is stored using text and images. - Graph views show which pages are connected to each other. - A search bar allows users to find information and connections. Nice to Have: Knowledge of Roam Research or Obsidian. How to Apply: Please reply to this ad with an overview of how you would approach this project and any initial thoughts on implementation.

2 days ago37 proposalsRemoteWhats app integration
This project requires developing a customized automated solution for large scale WhatsApp communication. The client needs to send personalized text messages to more than 200,000 recipients simultaneously through the popular messaging platform WhatsApp. The proposed system should be able to connect to the client's user database to extract requisite contact details like mobile numbers and fetch personalized message templates assigned to different user segments. It is imperative that all communication is sent while adhering to WhatsApp's platform policies and terms of use. The automated messaging mechanism developed should be scalable to handle such high volumes of concurrent outbound deliveries without encountering errors or delays. It must employ intelligent throttling techniques to stagger message dispatch over an extended period if required by WhatsApp APIs. Detailed logging and reporting functionalities are important to track message transmission status for each contact. The interface for operators should be intuitive and allow easy template management, recipient filtering, scheduling message runs. Security and privacy of user data being accessed and transmitted needs to be of utmost priority. Advanced technical and WhatsApp integration skills are necessary to take up this challenging project. Knowledge of application development, automation, APIs and messaging protocols is a pre-requisite. Creating a robust, policy-compliant and high performance solution within the stipulated timeline will be the key objective.
