🎉 Exoplanet Hunters Backend - First Production Release

✨ Highlights

This release marks the complete implementation of the Exoplanet Hunters AI Analysis Service, featuring full-stack ML inference, real-time visualization, and production-ready deployment.

🚀 Key Features

Machine Learning

  • ✅ Random Forest 3-Class Classifier (12.3 MB, 300 estimators)
  • ✅ Ensemble Voting Classifier (14.0 MB, multi-model ensemble)
  • ✅ CSV/DAT File Support (5GB max upload)
  • ✅ Real-time Predictions (~300ms for 100 rows)
  • ✅ Confidence Scores (probability estimates)

Backend API

  • ✅ FastAPI Framework (Python 3.11)
  • ✅ /api/analyze Endpoint (POST multipart/form-data)
  • ✅ Model Selection (random_forest or ensemble)
  • ✅ Error Handling (comprehensive validation)
  • ✅ Health Checks (/health endpoint)
  • ✅ API Documentation (Swagger UI + ReDoc)

Frontend

  • ✅ React 19 + Vite (modern tooling)
  • ✅ File Upload Component (drag-and-drop support)
  • ✅ Loading Progress (space-themed animations)
  • ✅ 3D Visualization (Three.js + React Three Fiber)
  • ✅ Result Dashboard (SummaryCard + CandidatesList)

Infrastructure

  • ✅ Docker Compose (one-command deployment)
  • ✅ Nginx Reverse Proxy (SSL + HTTP/2 + Gzip)
  • ✅ PostgreSQL 15 (data persistence)
  • ✅ Redis 7 (caching + queue)
  • ✅ MinIO (S3-compatible storage)

📊 Test Results

125/125 tests passing with 85%+ coverage:

  • 48 backend tests (ML predictor + API + integration)
  • 55 frontend tests (components + pages)
  • 22 E2E tests (Playwright)

Test-Driven Development throughout:

  1. Write tests first (RED)
  2. Implement code (GREEN)
  3. Refactor and optimize (REFACTOR)
