Built, shipped, running.

Three games I designed and built solo, an industrial tool built with my team and a platform co-built with a friend. More are on the way under my studio, Calkap Labs.

GameSoloWeb · iOS

Imperatlas

A geography quiz that becomes a conquest strategy game. Answer questions to earn gold, then spend it to build an army and take land in a world that keeps changing.

  • Twelve quiz modes across 198 countries: flags, capitals, silhouettes, landmarks, currencies, city hunts, population and area.
  • Conquest: envoys, alliances, sanctions, trade and attacks. The world moves on while you’re away, and the news tells you what happened.
  • A rotatable 3D globe, and historical starting points from 1071 (Manzikert) to today’s map.
  • Runs in any browser with no install; also on the App Store.

Built with TypeScript, React Native and Expo.

VocabWonder

A word puzzle that grows your vocabulary while you play: spin the letters, build words, fill the crossword grid, and tap any solved word to see its meaning and an example sentence.

  • Eleven languages — English, Turkish, Spanish, French, German, Italian, Russian, Chinese, Japanese, Korean and Arabic — and 100+ combinations to learn one language through another.
  • 250+ levels per language, a meaning and an example for every word, and offline play.
  • The dictionaries and levels are produced and checked with LLM pipelines I built for the game.

Built with JavaScript and Capacitor.

Ortam

A Turkish party word game for a group of friends, played together on one phone: set up teams and get your team to guess as many words as possible before time runs out.

  • Four modes: Classic, Reverse, Silent and Challenge.
  • Team and player management, and selectable word packs.
  • Unlimited play, no sign-up.

Built with TypeScript, React Native and Expo.

Industrial toolWith my teamAutoCAD · Windows

CutFlow

An AutoCAD plugin for laser-cutting shops. It takes an order of hundreds of part files and turns it into one clean drawing that’s ready for nesting software.

  • Brings every DXF/DWG file in a folder into a single drawing, sorted by thickness.
  • Reads material, thickness and quantity from the file names and labels every part with them.
  • Adds bend notes, cleans centre marks and produces a weight breakdown.
  • For AutoCAD 2025 and 2026 on Windows 10 and 11. Version 2.0.

Built with C# and .NET 8.

Ready — its website is coming soon.

Web platformCo-built with a friendTurkish

Fakültem

A decision platform for university applicants in Türkiye (YKS and DGS). It turns “is my score enough?” into “which university and programme suit me?”.

  • Base scores and success rankings, YKS and DGS score calculators, and side-by-side comparisons of programmes and universities.
  • A preference list of up to 24 choices, each labelled safe, ideal or risky against the applicant’s ranking.
  • An AI advisor.
