Computer Engineering graduate building real-time player-behaviour prediction, architecture for adaptive gameplay systems, and measurable interactive software.

Based in Istanbul, Türkiye · Open to international opportunities

01 / Flagship system

SpaceLumin

Verified playable build

Lumin Flow: Utopia Run

A playable Three.js browser game used to explore real-time player-state prediction, telemetry, and adaptive gameplay architecture.

I designed and implemented the gameplay systems, telemetry pipeline, Markov prediction model, runtime overlay, leakage-safe evaluation system, deterministic tests, and supporting PWA tooling.

Current evidence

What the repository proves today

Implementation evidence, not aspirational metrics.

VerifiedPlayable 3D build

Sector progression, enemies, pickups, HUD, and persistent progression run in the browser.

Verified16/16 evaluator tests

Deterministic coverage of event resolution, deduplication, model isolation, and exception-safe instrumentation.

VerifiedTwo modes + F3 overlay

Frozen and prequential evaluation are separated, with read-only runtime inspection.

VerifiedIsolated instrumentation

Evaluation cannot modify production predictions; hook failures are exception-safe.

In evaluation

Human-session evaluation in progress

Final accuracy is intentionally not reported yet. Controlled human-session data, baseline comparison, latency distribution, calibration, and confidence intervals remain pending.

Review evaluation design
Known limitations

Advanced adaptive paths are not active, gameplay does not yet consume the calculated multipliers, and statistically meaningful human-session evidence is still pending.

02 / Supporting work

Selected engineering projects

Only work with inspectable evidence.

03 / Supporting analysis

Research & technical writing

Methodology, clearly separated from shipped systems.

04 / Demonstrated use

Engineering capabilities

Grouped by evidence, not keyword count.
