Hey Dev community! 👋
I’m Dimitris Leventis, a developer from Greece, and I wanted to share a bit of my journey building real-world projects, learning to code, and starting my agency — all before finishing high school.
💡 From Curiosity to Creation
I started learning HTML, CSS, and JavaScript out of curiosity. That curiosity turned into passion when I realized I could build tools, not just websites — tools that solve real problems.
That mindset led to the creation of Leven Inc. — a digital agency I founded to work with real clients on branding, SEO, e-commerce, and web/app development.
🛠️ What I’ve Built
Leven Inc. – A growing agency with real clients and measurable impact.
StudyBuddyApp.com – An AI-powered study assistant that turns homework into quizzes and study plans.
Eco-Market – A grocery price comparison tool for Greece to help people save money.
SafeInternet.gr Games – Educational mini-games for cybersecurity awareness.
All projects are built with stacks like React, Node.js, TailwindCSS, and sometimes Python on the backend.
🧠 Learning from the Best: Harvard CS50 & Python
To sharpen my skills, I completed CS50’s Introduction to Programming with Python.
It helped me deepen my understanding of:
Functions and abstraction
OOP and data structures
Error handling and testing
It’s a tough course, but worth every hour.
🏆 National Hackathon Winner
One of my proudest moments was winning 1st place in the 7th School Hackathon “SELMA” in Greece.
Our project focused on [brief project idea if you want to add it] — and it showed me the power of teamwork and thinking fast under pressure.
📚 What’s Next?
I’m working on improving StudyBuddyApp with AI and expanding my agency’s impact.
I’m also preparing for university, where I hope to combine tech, design, and entrepreneurship even further.
