Professional Networking Platform

The project aims to develop a Professional Networking Platform, emulating core LinkedIn functionalities. The initial scope focuses on essential features, acknowledging that replicating all of LinkedIn is infeasible. Key functionalities include user authentication, comprehensive profile management (basic info, experience, education, skills), connection management (requests, acceptance, network display), content sharing (posts, feed, likes, comments, basic moderation), direct messaging, user search, and real-time notifications. Non-functional requirements cover performance, scalability, security, usability, and maintainability. A modern technology stack (React/Vue, Node.js/Python, PostgreSQL/MongoDB, WebSockets, Cloud Hosting) is proposed. Advanced AI/ML, complex job boards, company pages, learning platforms, events, premium features, advanced analytics, multi-language support, and video conferencing are explicitly out of scope for this initial phase, but considered for future expansion.

The project aims to develop a Professional Networking Platform, hereafter referred to as "the Platform," which will emulate the core functionalities of established professional social networking sites like LinkedIn. The objective is to provide users with a robust environment for professional networking, profile management, content sharing, and communication. The scope of this initial development phase will focus on implementing a foundational set of features essential for a viable professional networking platform, acknowledging that replicating *all* features of a complex, globally scaled platform like LinkedIn is beyond the scope of a typical clone project. The architecture will be designed to be extensible for future enhancements.

The system shall provide secure mechanisms for user authentication and session management. 1.1.1 User Registration: The system shall allow new users to register using an email address and password. Upon registration, a verification email shall be sent to the provided address. The user account will remain inactive until the email is verified. 1.1.2 User Login/Logout: Registered and verified users shall be able to log in using their credentials. The system must provide a secure logout function that terminates the user session. 1.1.3 Password Management: The system shall provide a 'Forgot Password' feature allowing users to reset their password via a secure link sent to their registered email. 1.1.4 Session Management: The system shall implement secure, token-based (e.g., JWT) session management to maintain user state across requests and protect against session hijacking.

The system shall allow users to create, manage, and display their professional profile. 1.2.1 Profile Creation and Editing: Users must be able to create and edit their personal profiles with the following sections: - Basic Information: Name, professional headline, current location, contact details (email, phone - visibility configurable). - Work Experience: A list of positions including company, title, dates of employment, and a description of responsibilities. - Education: A list of educational institutions attended, including degree, field of study, and dates. - Skills: A section to list professional skills. Other users in their network can endorse these skills. - Profile Media: Users shall be able to upload and change a profile picture and a background banner image. 1.2.2 Profile Visibility: Users shall have the option to set their profile as public (visible to all users) or private (visible only to their connections).

The system shall enable users to build and manage their professional network. 1.3.1 Send Connection Request: Users shall be able to find other users and send them a connection request. 1.3.2 Manage Connection Requests: Users shall be able to view pending incoming connection requests and choose to either accept or decline them. 1.3.3 View Network: Users shall be able to view a list of their first-degree connections. 1.3.4 Remove Connection: Users shall have the ability to remove an existing connection from their network. This action shall be reciprocal (both users are removed from each other's connection list).

The system shall provide a central feed for users to share and consume content from their network. 1.4.1 Post Creation: Users shall be able to create and share posts containing text, uploaded images, or external links. 1.4.2 News Feed: Each user shall have a personalized news feed on their homepage that displays posts from their connections, sorted chronologically with the newest posts first. 1.4.3 Post Interaction (Reactions): Users shall be able to 'like' or apply other simple reactions to posts in their feed. 1.4.4 Post Interaction (Comments): Users shall be able to write and post comments on posts in their feed. 1.4.5 Content Moderation: The system shall provide a mechanism for users to report posts they deem inappropriate. Reported content will be flagged for administrator review.

The system shall facilitate private communication between connected users. 1.5.1 Direct Messaging: Users shall be able to initiate and participate in one-on-one text-based conversations with their connections. 1.5.2 Real-time Delivery: Messages shall be delivered in near real-time, with visual indicators for message sending, delivered, and read statuses. 1.5.3 Message History: The system shall persist and display the full conversation history between two users.

The system shall allow users to find other people on the platform. 1.6.1 User Search: A search bar shall be available to allow users to search for other users by their full name, job title, or current company. 1.6.2 Search Filtering: The search results page shall provide basic filters to refine results (e.g., by location, company).

The system shall inform users of relevant activity on the platform. 1.7.1 Real-time Notifications: Users shall receive in-app, real-time notifications for the following events: - New incoming connection request. - A sent connection request has been accepted. - Someone liked/reacted to their post. - Someone commented on their post. 1.7.2 Notification Center: A dedicated area in the UI shall display a history of recent notifications, with an indicator for unread notifications.

2.1 Performance: The platform must be responsive. Core user interactions (page loads, feed scrolling, search results) must complete in under 3 seconds on a standard broadband connection. 2.2 Scalability: The architecture must be designed to horizontally scale to support an initial user base of 100,000 active users and be capable of expanding to support millions of users in the future. 2.3 Security: The platform must adhere to industry-standard security practices, including hashing and salting passwords, protection against SQL injection and XSS, and use of HTTPS for all data transmission. 2.4 Usability: The user interface must be intuitive and follow established design patterns for social networking platforms to ensure a minimal learning curve for new users. 2.5 Maintainability: The codebase must be modular, well-documented, and include a comprehensive suite of unit and integration tests to facilitate ongoing maintenance and feature development. 2.6 Technology Stack (Proposed): - Frontend: React.js or Vue.js - Backend: Node.js (with Express.js) or Python (with Django/Flask) - Database: PostgreSQL for primary relational data. JSONB fields may be used for flexible data structures like profile sections or posts. - Real-time Communication: WebSockets (e.g., using Socket.IO library). - Cloud Hosting: Deployed on a major cloud provider such as AWS, Google Cloud, or Azure.

The following features and functionalities are explicitly excluded from the scope of the initial development phase but may be considered for future releases: - Advanced AI/ML-driven features (e.g., personalized job recommendations, content suggestions, skill assessments). - Complex job board functionalities (e.g., advanced application tracking, recruiter tools). - Company pages and organizational tools. - Learning platforms (e.g., LinkedIn Learning). - Events management. - Premium subscriptions and monetization features. - Advanced analytics and reporting for users or administrators. - Global multi-language support (initial focus on English). - Video conferencing or advanced media sharing (e.g., video posts).

The change refines this into a concrete, actionable scope by defining a core set of essential features for a professional networking platform clone. This makes the project feasible, provides clear boundaries for development, and allows for a structured approach. The addition of non-functional requirements and a proposed technology stack further enhances the clarity and implementability of the requirement. Explicitly stating out-of-scope items manages expectations and provides a roadmap for future development.
