Sentinance: Stock Market Sentiment Analysis Platform

Sentinance is a full-stack, real-time sentiment and event tracking platform for retail stock traders and small fund managers. It aggregates Reddit (and soon Twitter/News) data to provide real-time sentiment graphs, event detection, and custom alerts for stock tickers.

Features

• Real-time sentiment analysis for stocks using Reddit data
• Interactive dashboard with sentiment timelines, heatmaps, and trending mentions
• Backend API (FastAPI) with NLP pipeline (FinBERT)
• Frontend (React + Vite + TailwindCSS) with live data visualizations
• Modular, extensible codebase for future Twitter/News integration

Tech Stack

• Frontend: React, Vite, TailwindCSS, Recharts
• Backend: Python, FastAPI, PRAW (Reddit API), HuggingFace Transformers (FinBERT)
• Database: (Planned) PostgreSQL, Redis, Pinecone/Weaviate
• DevOps: Docker, GitHub Actions (planned)

How It Works

• The frontend fetches live sentiment data from the backend API (e.g., /sentiment/reddit?ticker=AAPL).
• The backend scrapes Reddit for posts about the ticker, runs sentiment analysis, and returns results to the frontend.
• The dashboard visualizes this data in real time.

Planned Features

• Twitter and News integration
• Semantic search and event detection
• Custom alerts and notifications
• User authentication and personalized dashboards
