Experience

A Customizable Pipeline

https://github.com/iamonur/the_legendary_pipeline

I developed this customizable pipeline for my master thesis. It generates maze-like levels using cellular automation, creates protocol meta language (PROMELA) code for the game level WRT custom rules, and verifies the game level. The procedure is automated and customizable.

GoF Design Patterns' Implementations in C++

https://github.com/iamonur/cpp-design-patterns

This CMake project includes implementations of Gang of Four (GoF) design patterns. All the patterns included in the project are unit-tested with the help of a tiny unit testing library of acutest.

Simple Flutter Calculator App

https://github.com/iamonur/calc

A Material-based Flutter calculator app fully developed by me. The purpose was to get familiar with Dart and how to develop and deploy Flutter applications, especially in the Android setups. For calculations, I have used expression trees.
