👋 My Developer Story – Building CarbonCrush

Hi! I’m the creator of CarbonCrush, and I made it because I care about the planet—but I also care about keeping things simple and realistic.

One day, I was trying to lower my carbon footprint. I Googled stuff. I downloaded apps. But everything I found was either:

  • Way too complicated,
  • Asking me to give up my whole lifestyle, or
  • Just showed me big scary numbers and no actual advice.

That’s when I thought:
“Why isn’t there something that just helps me make better choices without making me feel bad?”

So I built it.


🌱 What Is CarbonCrush?

CarbonCrush is an AI-powered climate assistant.
You tell it how you live—like how you travel, what you eat, or what you buy—and it gives you:

  • Your estimated emissions
  • Smart, easy swaps to reduce your footprint (like “take the train instead of an Uber this week”)
  • Weekly reports that show how much carbon you’ve crushed

The whole idea is:

🧠 Small steps. Big impact. No guilt.


🤖 How It Works (But In Chill Words)

CarbonCrush uses two smart AIs:

  • 🧠 Claude (by Anthropic) – understands how people think and gives friendly, helpful advice that makes sense
  • 🧮 GPT-4o (by OpenAI) – does the carbon math and helps explain the swaps with real numbers

They work together like a team:

  • Claude helps you feel heard
  • GPT-4o helps you make better choices

🧰 What I Used to Build It

Here’s my tech stack:

  • Next.js 14 – for the app itself
  • Tailwind CSS – to make it look clean and modern
  • shadcn/ui – for all the components
  • Supabase – to store user data, handle auth, and run backend logic
  • Vercel – to deploy everything and make it fast

I made it mobile-first so you can use it anywhere—on the train, at lunch, even while waiting for coffee.


🧑‍💻 Why I Built It (In My Words)

I built CarbonCrush because I believe most people want to help the planet. They just don’t know where to start—or they feel like it’s too hard.

So I made something I wish I had:
A tool that helps people do one thing better this week.
That’s it.
Not 100 things. Just one.

Because if thousands of people do one small thing each week, that turns into real change.


🚀 What’s Next?

I’m excited to keep going. Here's what I plan to add:

  • Apple Health + Google Fit integration (for fitness-related footprint tracking)
  • Group challenges (friends, families, even workplaces!)
  • Climate rewards marketplace
  • Premium tools for teams or eco-friendly brands
