QBluePrint (2025) (open-source)

I developed QBlueprint, a visual programming tool built with Qt C++ and QML, designed to help users create logic flows through a simple drag-and-drop interface without the need for coding. The application features a variety of functional boxes, including logical, mathematical, and comparison operations, as well as input/output sources like TCP/UDP communication and chart visualizations. Users can connect these boxes to define data flows and create complex logic visually. The tool supports saving and loading blueprints as JSON files, dark and light themes, and zooming for better navigation. Inspired by Unreal Engine's Blueprint system, QBlueprint is aimed at providing an intuitive way for non-coders to implement logic and create custom workflows. The project is still in its early stages, with plans for ongoing development and feature expansion. You can find the source code and releases on GitHub and watch demo videos on my YouTube channel .

Ultrasonography (2025)

I worked as a C++ developer on an ultrasound sonography imaging machine, using Qt and QML for UI and system development. My responsibilities included measurements, touch panel and system integration. I developed over 500 measurement tools, including spline, trace, ellipses, angles, volume, and numerous application-specific calculations, solving complex mathematical problems to ensure accurate results. Additionally, I designed and built a custom virtual keyboard from scratch, featuring multiple pages, body labels, body markers, multilingual support, and various advanced functionalities. To enhance precision, I developed a magnifier tool that allowed doctors to place points with high accuracy. The measurements and most GUI elements were inspired by the latest Philips ultrasound imaging sonography machines, ensuring a modern and intuitive user experience. I also contributed to various other features that improved the overall functionality and usability of the system.

Avionics ARINC 429 Logger (2022)

I developed a Windows-based software solution for hardware designed to capture and analyze ARINC 429 data, using Qt C++, QML, and the Modbus TCP protocol for communication. The software connected to the hardware, which was integrated into commercial aircraft facilities, enabling it to capture ARINC 429 packets and transmit them back for real-time analysis. It supported bi-directional communication, allowing users to configure the hardware, send essential commands, and manage data transmission. The software featured a real-time packet parser with over 50 ARINC 429 parsers, enabling users to view critical parameters instantly. Data was stored in a database for future analysis, and users could replay pre-captured data for further investigation. For visualization, I implemented interactive charts using WebEngine and CanvasJS, where data was directly fed from the C++ side to ensure high-performance rendering. This approach allowed the software to efficiently handle and display large datasets with thousands of points in real-time, ensuring fast and smooth visualization for both online and offline analysis, even with multiple data channels on a single chart. Additionally, the software allowed users to create and transmit custom TX packets at predefined intervals, either manually or by importing data from CSV files for automated transmission. Users could also configure custom channel IDs, labels, and equipment settings, selecting predefined parsers to process packets accordingly. Many of the software’s features were inspired by Ballard Technology's Copilot software, ensuring a powerful and user-friendly experience for ARINC 429 data analysis.

As the sole software developer for a cutting-edge digital instrument cluster project, I utilized Qt, QML, and C++ to design and develop a highly efficient and optimized application. Inspired by the sophisticated designs of renowned car manufacturers like BMW and Mercedes-Benz, I created multiple themes to enhance the user experience. The design encompassed all aspects of a digital cluster, including Diagnostic (UDS), networking (OSEK-NM) and other essential protocol implementations specific to each car manufacturer. The product was specifically tailored for the IKCO TARA, SAIPA SHAHIN/ ARIA vehicles integrating with their CAN matrix data. The application achieved a remarkable 60 FPS on an embedded Linux running on a single core SOC, ensuring a smooth and responsive performance with fast boot times.

HMI Launcher App (Desktop Environment) (2023)

As the sole software developer, I Development and design of a comprehensive launcher application for an embedded-Linux-based HMI, adhering to XDG specifications. Utilizing QT, C++, QML, and the Wayland protocol, I engineered a robust windowing system, seamless task-switching capabilities and a full desktop environment. From scratch, I developed essential software components including a file browser, image viewer, text editor, and settings manager. The launcher environment, designed to mirror the user-friendly experience of Android, featured quick settings, a search function, and a customizable home page.
