Project What it does Highlights
Logistics Fleet & Network Optimization · demo Demand forecasting → fleet-mix routing → bottleneck early warning for a 10-hub, 90-route freight network (synthetic data) OR-Tools ILP solves the full network to proven optimality in ~0.02 s (benchmarked against an ALNS heuristic: 2–17% costlier); LightGBM + LSTM ensemble at 10.6% holdout WAPE; message-passing GNN trained on simulated scenarios; 19 tests + CI
Space Debris Tracking System · demo Conjunction screening for Turkish satellites from public TLE data SGP4 propagation, TCA refinement, Chan-series collision probability validated against numerical integration; 22 tests + CI
Scout DSS Football scouting decision-support prototype TOPSIS role-based ranking and centered cosine-similarity matching in Streamlit; Understat xG/xA data with the simulated metrics clearly disclosed; tests + CI
Ottoman Lexicon Widget Ottoman / historical Turkish vocabulary app for Android with home-screen widgets Next.js + Capacitor + Firebase, native Android home-screen widgets in several sizes
UGC Creator Marketplace Two-sided brand ↔ creator marketplace MVP FastAPI + SQLModel + JWT auth; server-side application state machine with ownership checks; API tests + CI
Market Intuition Chart pattern-recognition training tool React 19 + Vite + Lightweight Charts; 56 historical scenarios with data-integrity tests + CI
