The studio

A small studio with serious engineering.

naboolabs is an independent studio based in Sofia, Bulgaria. We design and build every part of our games ourselves - from the first sketch of a puzzle to the servers that keep multiplayer matches in sync.

Before games, we spent years building systems that process millions of events a day across security, applied AI and real-time platforms. That discipline is what our games stand on.

Game design

Puzzles and word games with real depth, difficulty that adapts to the player, and new content long after launch.

Real-time & multiplayer

Live rooms, turn-based play and leaderboards on queue-driven, low-latency infrastructure built for thousands of concurrent players.

Production engineering

Scalable backends, AI integrations and cloud architecture - the same rigor we bring to platforms like Ubiscore goes into everything we ship.

Beyond games

Platforms we've built

The engineering behind our games also powers products that run at scale.

Live

Ubiscore

Automated web compliance scanner

A high-throughput platform that scans thousands of websites daily for security, privacy and compliance issues - DNS, SSL, email configuration, cookie policies and GDPR alignment. Queue-driven schedulers and AI-assisted analysis handle complex checks reliably and at scale.

  • 15,000sites scanned / day
  • 98.5%accuracy

Kind words

Signals

What partners say about working with us.

“We've been sending him projects for two years now and honestly, I don't know how he does it. Fast turnaround, asks the right questions upfront, and his code just works. Our clients are happy, we're happy. Can't ask for more than that.”

CEO, DevForge Solutions

“He built our entire compliance scanning backend - crawlers, AI analysis, queue system, everything. We're processing 15k sites a day with zero drama. When we had an edge case with SSL checks, he fixed it same day. That's the kind of engineer you want on your team.”

CTO, Ubiscore

“I needed some Python scripts to pull stock data and run calculations. He whipped them up in a weekend, explained how everything worked, and even added error handling I didn't ask for. Saved me weeks of headaches. 10/10 would hire again.”

Marcus Chen, Independent Trader
