  • Reliability: Known for stability and data integrity.
  • Advanced Features: Supports indexing, full-text search, and complex queries.
  • Scalability: Handles large datasets efficiently.

4. AI Models

Core Technologies:

  • FastAPI: For exposing AI models and handling inference requests.
  • Ollama: Pre-trained language models (LLMs) for project idea generation, skill recommendations, and enhanced matchmaking.

Key Benefits:

  • Speed: Optimized for quick inference.
  • AI Customization: Leverages LLMs for intelligent features.

5. Containerization & CI/CD

Core Technologies:

  • Docker: For containerizing backend and AI services, ensuring consistent performance across environments.
  • GitHub Actions: Automates the build, test, and deployment pipeline.

Key Benefits:

  • Portability: Ensures smooth transitions from development to production.
  • Automation: CI/CD pipelines reduce manual tasks and improve reliability.

6. Hosting & Deployment

Core Technologies:

  • Fly.io: For scalable cloud hosting of the backend and AI services.
  • Render: For hosting backend services for the Flutter app.

Key Benefits:

  • Scalability: Seamlessly scales to handle global traffic.
  • Ease of Use: Simplified setup with automatic SSL and configuration.

7. Version Control

Core Technologies:

  • Git: Version control for tracking code changes.
  • GitHub: Centralized code hosting with tools for collaboration (pull requests, issue tracking, CI/CD integration).

Key Benefits:

  • Collaboration: Streamlines team workflows and code reviews.
  • Version Management: Enables easy rollbacks and branch management.
