About — LinguaHero

Hey, I'm Luka 👋

I'm 11 years old and I build things with Python. Not toy projects. Real ones. The kind you can open in your browser right now.

🚗 How It All Started

It started in the car.

My dad was firing questions at me about English irregular verbs on a drive. "What's the past tense of 'go'?" Easy. "What about 'arise'?" ...not so easy. I didn't know all of them, and I wasn't happy about that.

But then I thought — why just sit down and memorise a boring list? Why not build something that makes studying fun? Not just for me, but for everyone?

So I did. That's how LinguaHero was born. 🚀

💻 From Idea to Real Website

This isn't just a school project. This is me learning how the whole thing works — from writing the first line of Python to having a real website with a real domain that anyone in the world can open.

Here's everything I learned along the way:

🐍

Python & Flask

The brain of the app. All the game logic, level unlocking, sessions and routes — written by me in Python.

💻

Visual Studio Code

This is where I write my code every day. It feels like a proper developer setup and I love it.

🐙

GitHub

Every change I make gets pushed to GitHub. It keeps the full history of everything I've ever built. If I break something, I can go back!

🚀

Render

This is where the app lives on the internet. I deploy it myself after every update.

🌐

Custom Domain

I have a real domain name connected to the app. That part felt really cool.

🗄️

Databases

I use SQLite to count unique visitors. I learned that IP addresses are personal data under GDPR and anonymised them with a hash function.

🎨

HTML & CSS

I design the pages too. Making things look good on mobile is harder than it sounds!

📊

Analytics

I added GoatCounter so I can see how many people visit. It's privacy-friendly so no cookie banners needed.

🎯 How I Build It

I use something called vibe coding — which basically means I build real things first, and figure out the concepts along the way. No dry textbooks. No boring exercises. Just me, VS Code, and a problem to solve.

I'm learning Python, but also everything around it — APIs, databases, deployment, version control, analytics, GDPR compliance, and a lot more. My goal is to master the whole stack, not just one piece of it.

😄 My Dad Helps Too

I build everything myself, but my dad supervises the project — he helps with big decisions, points me in the right direction when I'm stuck, and makes sure I'm learning the right way.

He also started the whole thing by asking me those irregular verb questions in the car. So I guess I owe him a thank you. Maybe.

📧 Say Hello!

Got a suggestion? Found a bug? Just want to tell me something is cool?

[email protected]

I actually read every message. It helps me grow as a developer!

🔒 Privacy & Data

I care about this stuff — I actually learned about GDPR while building this app:

✅ No personal data collected or stored
✅ No tracking cookies — ever
✅ Visitor counting uses an anonymised hash of your IP — it cannot identify you
✅ Analytics by GoatCounter — privacy-friendly and cookie-free
✅ Your progress is saved in your browser only — it never leaves your device
