GreenSteps
> AI-powered sustainability assistantDemo: greensteps.devlix.org
Built this during a hackathon. The goal was simple: make sustainability less preachy and more usable in real life.
What it does
• Step-by-step, personalized guidance
• Interactive AI flows instead of info dumps
• Focus on practical actions, not “save the planet” lectures
Timeframe
• ~2 days, end to end
My part
• Backend + AI
• Most of the frontend
Tech
• FastAPI backend on EC2
• Gemini Live API (audio)
• PostgreSQL (RDS)
• React frontend on S3 + CloudFront
• CloudWatch for logs
What I learned
• Time limits force better product decisions
• Real-time AI + WebSockets get messy fast
• People engage more when tools guide, not judge
Not perfect, but it works and we shipped. Iterating next.
