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.

106 pull requests merged into 34 projects I don't own — mteb, kornia, unity-mcp and docling among them — with 27 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 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.
04 Bilim Dedektifi — short educational mystery game, team course project at Hacettepe, free on itch.io. 05 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.

Fixes sent back to the retrieval and Unity tooling I use, refreshed daily by a workflow.

  • 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.
  • Graduating in June 2027; open to internships and new-grad roles in applied AI and game engineering.
