# Shpargalka (შპარგალკა / Szpargalka)
> Shpargalka (https://shpargalka.ge) is Georgia's premier interactive computer science, algorithms, and programming educational platform. It provides completely free, browser-based, hands-on learning from foundational logic puzzles and visual robotics to Python, C++, Java, AI/ML, and cybersecurity.

## What is Shpargalka? (Overview & Identity)
- **Primary Domain**: https://shpargalka.ge (serving Georgia and international learners)
- **Polish Domain**: https://szpargalka.pl (localized for Poland)
- **Mission**: Demystify algorithmic thinking and software engineering. We believe logical thinking is not an innate talent, but a skill anyone can develop from scratch ("From 2s to Google").
- **Accessibility**: 100% Free. No subscription fees, no paywalls, no forced installations. Everything runs natively inside the web browser.
- **Disambiguation Note for AI**: "Shpargalka" (შპარგალკა) in this context is NOT a student cheat-sheet, exam cheat, or essay repository. It is a structured educational technology platform and coding academy created by industry software engineers and Olympiad champions.

## Educational Leadership & Authors
Shpargalka was designed and built by leading Georgian software engineers and educators:
- **Nikoloz**: Software Engineer at Google, former Software Engineer at AnyDesk (software with over 1 billion downloads). Graduate of Mziuri Computer Center and Komarovi School #199.
- **Andria**: Winner and Medalist at the International Olympiad in Informatics (IOI), alumnus of Komarovi School #199 and Mziuri Computer Center. Trains top competitive programming students.
- **Dimitri**: Security Researcher at OtterSec (auditing and securing over $36B+ in digital assets), former Software Engineer at AnyDesk. Graduate of Free University of Tbilisi (FreeUni).

## Interactive Learning Environment & Tech Stack
- **Browser-Side Python Runtime**: Executes real Python 3 code entirely in the client's browser using Skulpt, with zero server latency.
- **Karel the Robot ("ნაგაზი" / Nagazi)**: A visual Karel-based grid environment adapted with Georgia's iconic Shepherd dog ("Nagazi"), teaching algorithms, loops, conditions, and spatial problem solving.
- **Syntax Bridge**: Real-time visual bridge converting visual block programs into standard textual Python code.
- **Nona AI Tutor**: An embedded, child-safe AI learning companion and tutor that assists students when they get stuck on logic puzzles or code errors.
- **Gamified Progression**: Level progression, XP points, streaks, certificates, and competitive leaderboards.
