RizgarOzan/README.md
Rızgar Ozan, AI systems and game tools programmer. I build games, tools and AI systems.

rizgarozan.github.io · LinkedIn · itch.io · Hugging Face · rizgarozan7@gmail.com

I build games, tools and AI systems: retrieval evaluations that say which part of a RAG pipeline earns its cost, and game tools that score a level or catch a broken font before anyone ships it. Final-year Computer Education & Instructional Technology student at Hacettepe University, Ankara.

121 pull requests merged into 36 projects I don't own — mteb, kornia, docling and unity-mcp among them — with 21 more in review.

rizgarozan.github.io: a moonlit field where each sword standing in the ground is one of my projects; scroll down into the smithy for what I'm working on now.

Selected work

01 Turkish RAG Eval — 3 chunkers by 4 retrievers on a hand-labelled Turkish gold set. Best nDCG@10 per retriever: BM25 0.41, BM25 + 5-char prefix 0.51, hybrid RRF 0.61, dense (multilingual) 0.50, dense (Turkish model) 0.78.
02 Match3 Lab — C# match-3 rules core, readable level format, Unity editor tools and a bot simulator. The greedy bot's win rate falls from 100% on level 1 to 50% on level 6; the random bot from 70% to 3%. 1000 games per level. 03 Lockstep Tactics — C++20 tactics game, playable in the browser against an integer-only AI, that stays bit-identical across MSVC x64, Apple clang arm64 and WebAssembly: fixed-point maths, own RNG, per-tick replay hashes and a bisector that names the desync. 1000 of 1000 matches end on the same hash; 100 of 100 injected desyncs located; the AI wins 978 of 1000 against random orders.
04 Suspicious Delicacies — Unity 6 team project: a chef with a secret hunts friendly creatures for ingredients, cooks, serves and dodges suspicion; restaurant management welded to a turn-based RPG. I own the restaurant, customer AI, QTE, overworld and editor tooling. Demo in progress. 05 TMP Glyph Audit — Unity package that finds every TextMeshPro text the fonts cannot draw, through TMP's real fallback chain. Editor window plus CI exit codes.
06 Bilim Dedektifi — short educational mystery game, team course project at Hacettepe, free on itch.io. 07 Code-Enigma — React 19 academic progress platform built with İlkhan Arda Akmaca; I built the dashboard, peer comparison markers and the filter and settings controls.

Now · October 2026

  • Turkish RAG Eval 0.2.0 is on PyPI: 300 queries (58 hand-labelled, 242 LLM-drafted and double-labelled) across five models, with the dataset on Hugging Face. The MTEB task is in review (mteb#5615), and the drafted queries are open for human review as good first issues.
  • Lockstep Tactics is playable: a C++20 tactics game checked on every push to be bit-identical between MSVC x64, Apple clang arm64 and WebAssembly, with an integer-only AI that wins 978 of 1,000 matches against random orders. Play it in the browser; a saved match verifies tick by tick on any machine. Next: two browsers exchanging commands over a relay.
  • Graduating in June 2027; open to internships and new-grad roles in applied AI and game engineering.
