Experience
Real-time Ground Control Station Software for UAVs
https://www.tusas.com/en/products/uav/operative-strategic-uav-systems/ankaA real-time air vehicle control software for UAVs using C/C++ and a model-based development environment.
I was involved in all software cycle stages using several tools, including SVN, Jira, Confluence, Telelogic DOORS., Jenkins, and Parasoft. I also authored many documents, including "Software Development Plan," "Software Design Standard," and "C Coding Standard." I coded IO management and HMI logic modules and developed a code generator to automate IO management and inter-partition communication.

Development of a Data Simulation and Monitoring Software
A real-time monitoring software with data simulation and UI creation, which I developed using C# and Python.
The software was extensively used by different teams and customers in all UAV projects. It injects and monitors all commands and status of system and equipment information. It can also connect many different endpoints, such as user datagram protocol, transmission control protocol, and serial, simultaneously. The user can create custom UI and algorithms using the Python engine.

Web-based UAVs Tracking and Live Video Streaming Application
An application developed using React, Spring Boot, GIS, and relational database management system technologies.
I led and architected the whole project. I developed the back-end modules to handle authorization and entity management and also built the system integration parts of the application.

Embedded Command and Control Software
https://www.tusas.com/en/products/uav/target-drone-systems/simsekA C/C++-based embedded command and control software runs on Linux and EP440 single board computers. It communicates different equipment and sensor over serial, discrete, and UDP interfaces. It uses ZeroMQ middleware for communication. I developed I/O, an operating system abstraction module, and created a ZeroMQ-based communication library for internal and external communication.
Code Generator for Network Communication Software
https://www.tusas.com/en/products/uavA desktop and command line application developed by C#.NET and T4 Toolbox. This software generates network communication and message parser codes using interface message definitions. It has an object model and code generator engine that can produce different programming languages such as C, C++, C#, and Java using T4-based templates. I developed all software from scratch. This software has been used by all UAVs software message parsing and network communications.
Web-based Document Management Application
An application manages the company document management system over an online system. The application was developed by ASP.NET, JavaScript, and Oracle and served in IIS. It handles over 10,000+ documents in daily usage. I created all software and worked as a full-stack engineer.
Solving Gaussian Elimination with C++ Parallel Programming by using MPI
An application solves the Gaussian elimination algorithm by using parallel programming techniques. It was developed by C++ and MPI libraries. I developed and tested all applications. The application runs on different Linux computers and communicates over the network.
RF Filter Design Software
https://tez.yok.gov.tr/UlusalTezMerkezi/TezGoster?key=UPP_Zu9isEmWGFXFCBYasSYV5FCY43ptNiWhLm0YLZ57QPDDEkugbWTqZTys4e8vIn this study, a Window-based computer program named Synthesis Software is developed to design filters with equal-ripple or maximally flat passbands and general stopbands using the cascade synthesis technique in the transformed frequency domain.
The synthesis technique applies to the lumped element and commensurate line distributed element filters with lowpass, highpass, or bandpass characteristics. Singly or doubly terminated filters can be synthesized.
One of the parts of the program is the response-plotting section. Insertion loss, return loss, time delay, phase, and Smith chart responses are calculated and displayed in this part. The other part is the user interface, which provides a user-friendly environment for typing in the parameters of the filter to be designed. This part uses synthesis and plot parts as modules.
