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. This summer I was a software intern at Barko Elektronik, where I set up a local LLM stack on company hardware, wired it to Active Directory, and built FastAPI services in Docker that feed Oracle data into live Power BI dashboards.

158 pull requests merged into 41 projects I don't own — mteb, kornia, unity-mcp and docling among them — with 17 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 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 998 of 1000 against random orders. 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 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 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, then 74% on level 7; the random bot from 70% to 3%, then 4%. 1000 games per level.
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 · November 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 dataset is now an MTEB task, TurkishRAGEvalRetrieval (mteb#5615, merged), 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 998 of 1,000 matches against random orders. Play it in the browser against the AI or against a friend in another browser: the two run in lockstep over WebRTC and compare hashes as they go.
  • Graduating in June 2027; open to internships and new-grad roles in applied AI and game engineering.
