Crypto markets move fast, but real-time public sentiment is scattered across Reddit, Twitter, and various news outlets. CryptoPulse bridges this gap by fetching, analyzing, and visualizing crypto-related sentiment in real time, empowering investors with smarter insights.

Key Features 🔥

• Fetch live crypto discussions from Reddit (Twitter limited due to new API costs )
• Analyze emotions behind the chatter using Vader and BERT AI models
• Aggregate sentiments into a single score using a custom-built Go service
• Visualize it through a sleek React.js dashboard
• Deploy seamlessly with Docker, GitHub Actions CI/CD, and Google Cloud Run
