Hey Dev.to! 👋

I'm a 15-year-old student developer from South Korea.

I just finished my first real production project — FuelScope AI.

An energy market intelligence dashboard that uses

Groq's Llama 3.3 70B to summarize real energy news in real time.

🔗 **Live Demo: https://fuelscope-ai.vercel.app**

This was my first time building something with:

Honestly learned more in 4 days building this than months of tutorials.

Gas prices and stock data are mock values —

the README includes guides for swapping in real APIs

(EIA, Alpha Vantage, etc.).

The AI news summaries are 100% live though.

I'm selling the template for $19 on Gumroad if anyone

wants to build on top of it:

Would love any feedback from the community! 🙏
