Experience

NEMSUITE

https://github.com/tkargioglu/NEMSUITE/blob/main/NMC2022_Abstract.pdf

A software tool for analyzing nanoelectromechanical sensing systems. The tool enables users to perform stochastic simulations that can substitute physical experiments. I have developed the tool using MATLAB and Simulink. The project was presented at the 18th International Workshop on Nanomechanical sensing.

Deep Recurrent Attention Model

https://github.com/tkargioglu/Deep_Recurrent_Attention_Model

This project was about deep-learning image recognition, focused on implementing RAM and different versions of DRAM. The models are tested on original and modified versions of MNIST and SVHN datasets. I have implemented the models in Julia.

ClearSky | Anti-drone System

http://web2.bilkent.edu.tr/shadef/

An anti-drone system comprised of detection, neutralization, and control units. The project started as an undergrad project and evolved into a startup. Along with a five-person team, we designed, developed, and marketed the product.

The detection unit identified drones using visual data and calculated the output with the position of a target drone. We trained deep neural networks using Python. The neutralization unit deployed a jammer with a directional antenna to eliminate the detected drones by distorting their communication. The controlling unit orchestrated the components and the decision-making process, among other things.

The system could send images to the neural network, positioning the antenna according to the detection unit's output and UI within the controlling unit. As the startup's general manager, I was involved in every step of the product's development.
