OmerHarmankayaC/README.md

Ömer Harmankaya

Industrial & Computer Engineering student at TED University, Ankara. I work where operations research meets software — scheduling, forecasting, retrieval — and I care about shipping things end to end rather than leaving them as notebooks.

Currently

  • Building a constraint-programming shift scheduler for security personnel at BOTAŞ facilities: OR-Tools CP-SAT, FastAPI, React, PostgreSQL.
  • Product lead for Vera Finance, a published iOS personal finance app — plus its RAG Q&A assistant.

Selected work
Shift Scheduling DSS Decision support tool for scheduling security personnel — CP-SAT solver, fairness and coverage constraints, five of six acceptance criteria met and the sixth analysed rather than hidden
LoadCast Hourly electricity demand forecasting for the Turkish grid — EPİAŞ pipeline, weather integration, LightGBM at 2.19% MAPE against the official plan's 2.63% · live
Vera RAG Assistant Fully offline retrieval-augmented Q&A — on-device embedding and inference, no network at query time · live
Portfolio This site — Vite/React, with live model output embedded straight from LoadCast

Two habits that show up in everything above: the numbers get reported as measured, and known limitations get their own section.
