STEM-HQ

A professional networking platform specifically designed for Science, Technology, Engineering, and Mathematics professionals.

Overview

STEM Network connects professionals across scientific and technical fields, facilitating collaboration, knowledge sharing, and career advancement within the STEM community. Our platform provides specialized features tailored to the unique needs of researchers, engineers, data scientists, and other technical professionals.

System Architecture

Backend Services

The backend is built using a microservices architecture, with each service contained in its own Docker container:

Service	Description	Technologies
Authentication API	User authentication and authorization	FastAPI, Pydantic, JWT
Profile API	User profile management	FastAPI, Pydantic
Connection API	Network connections and recommendations	FastAPI, Pydantic
Messaging API	Direct messaging between users	FastAPI, Pydantic, WebSockets
Content API	Posts, articles, and publications	FastAPI, Pydantic
Search API	Advanced search functionality	FastAPI, Pydantic, Elasticsearch
Analytics API	User engagement and platform metrics	FastAPI, Pydantic
Notification API	User notifications and alerts	FastAPI, Pydantic

Database

PostgreSQL serves as our primary database system:

• Main Database: Stores user profiles, connections, content, and other core data
• Analytics Database: Dedicated database for analytical data and metrics
• Schema Management: Uses Alembic for database migrations
• Connection Pooling: PgBouncer for efficient connection management

Frontend

The frontend is built with Vue.js, contained in its own Docker containers:

• Main Application: Vue.js with Vuex for state management
• Admin Dashboard: Separate Vue application for platform administration
• Mobile-Responsive Design: Ensures optimal experience across devices

Deployment Strategy

Initial Deployment (Development & Early Production)

The platform will initially be deployed on a hybrid local cluster consisting of:

• 1× Raspberry Pi 4 (4GB RAM)
• 1× Raspberry Pi 3B+
• 1× Full Tower PC
  • 32GB RAM
  • 6-core CPU
  • NVIDIA 1610 Super GPU
  • 4TB storage

Resource Allocation

• Raspberry Pi 4: Hosts lighter API services and background workers
• Raspberry Pi 3B+: Runs PostgreSQL database and Redis cache
• Full Tower PC: Hosts resource-intensive services, frontend applications, and potential machine learning services

Future Deployment (Scale-Up)

As the platform grows, deployment will transition to Oracle Cloud Infrastructure (OCI):

• Migration Strategy: Gradual migration of services to ensure minimal downtime
• Containerization: All services will remain in Docker containers for smooth transition
• Orchestration: Kubernetes for container orchestration and scaling
• Database: Managed PostgreSQL service for improved reliability and performance

Development Environment

Prerequisites

• Docker and Docker Compose
• Python 3.9+
• Node.js 14+
• PostgreSQL 13+

Setup Instructions

1. Clone the repository:

   git clone https://github.com/your-organization/stem-network.git
   cd stem-network

2. Set up environment variables:

   cp .env.example .env
   # Edit .env with your configuration

3. Start the development environment:

   docker-compose up -d

4. Access the development server:

   Frontend: http://localhost:8080
   API Documentation: http://localhost:8000/docs
   

CI/CD Pipeline

• Git Workflow: Feature branches with pull requests to main
• Automated Testing: Unit and integration tests run on each PR
• Deployment: Automatic deployment to development environment after successful merge
• Production Deployment: Manual approval required for production deployment

API Documentation

API documentation is automatically generated using FastAPI's built-in Swagger UI:

• Development: http://localhost:8000/docs
• Production: https://api.stemnetwork.com/docs

Database Schema

The core database schema includes the following main tables:

• Users
• Profiles
• Connections
• Skills
• Endorsements
• Posts
• Comments
• Messages
• Notifications
• Publications
• Projects

Monitoring and Logging

• Application Monitoring: Prometheus and Grafana
• Log Management: ELK Stack (Elasticsearch, Logstash, Kibana)
• Error Tracking: Sentry
• Performance Monitoring: New Relic

Security Considerations

• Authentication: JWT with refresh tokens
• Authorization: Role-based access control
• Data Encryption: TLS for all communications
• Database Security: Parameterized queries, least privilege access
• Input Validation: Pydantic models for request validation
• Rate Limiting: Implemented at API gateway level

Backup and Recovery
