Shift Solver — ShiftStudio

The CP-SAT engine that outgrew the hackathon: a FastAPI scheduling service for the ZARA women's section where I work — in active daily use, cutting the day's role-chart planning from about two hours to minutes (operational, self-reported).

Undergraduate Thesis — Channel Analytics

An ML pipeline that caught its own data leakage: from a fake-perfect ROC-AUC 1.0000 to an honest 0.713 that powers a prescriptive channel recommender.

PUSULA / COMPASS

A scoreless, evidence-based people-development and shift-placement platform for ZARA store coaches — built for the Inditex AI Hackathon 2026, and the birthplace of the CP-SAT engine that now runs my section's real schedule.

Teknofest Traffic Computer Vision

A classical image-processing pipeline for traffic scenes — 698 labeled images processed with OpenCV, no deep learning, advanced to the competition's second stage.

Telco Customer Churn

Churn prediction on the classic Telco dataset, built less for the score and more for the discipline: every run tracked in MLflow, every input shift visible in a drift report.

07

Automotive Sales Analytics

Exploratory analysis and feature engineering over a 100K+ row automotive sales dataset — the unglamorous cleaning work that every downstream model depends on.

Pandas · Feature engineering · EDA

CrmApp — Desktop CRM

A Windows Forms CRM I built as my object-oriented programming (NTP-2) term project: three clean layers, a generic repository over an embedded SQLite database, and full CRUD across customers, companies and activities — the fundamentals, done properly.

Prexamy — AI Exam & Net Coach

A two-person full-stack monorepo for Turkish exam prep (YKS, LGS, KPSS): a Flutter app, a NestJS backend with an LLM tool-calling orchestration layer, and the NLP intent-routing gatekeeper I built to decide when the AI should even be called.

Budgeify — Personal Finance App

A personal finance app — income/expense tracking, savings goals, calendar reminders — shipped to production on Vercel in a one-week sprint, with an insights engine that tells you how confident it is before it tells you anything else.

skdesign.online — Designer Portfolio

My first shipped client work: an editorial, monochrome portfolio for fashion designer Saliha Kılıç, live at skdesign.online — built to put 124 pieces of her real work in front, with GSAP scroll set-pieces that stay out of their way.
