Experience

Model-based User Interface Generation

I developed an embedded application using a model-based approach. It was a counterpart Vue.js application that served as a static web page. I connected both applications with WebSockets. The final product is an always-compatible user interface that can control and monitor everything, which is also carried within the embedded device itself. It reduced user interface development costs significantly because Vue.js components mostly generated it.

Program to Measure Modulation Transfer Function

MTF is a measurement for optical systems such as cameras or microscopes, which shows performance on different frequencies. I developed a program using MATLAB, which detects circles and lines, then calculates the angle of the target. After correctly detecting these using the given parameters, it calculates the Modulation Transfer Function of the optical system.

Unity Strategy Game

https://www.youtube.com/watch?v=S-zmnC0y_I0

I am developing a turn-based strategy game using Unity. It is inspired by "The Battle of Polytopia." I used hexagonal tiles and added distance-based logistics mechanics to the game. The game art is still being developed.
