I have been working with open source projects as a C++ programmer, with a focus on the Qt framework, for many years. My expertise in mathematics, combined with my creativity and problem-solving skills, has allowed me to excel in debugging programming issues. I have worked on several open source projects as owner, including Saaghar (a poetry software), SaagharBot (a Telegram bot), and Saahel (a LaTeX presentation template). In addition to these projects, I have also been a team member of the Falkon browser project, which is part of KDE, from 2012. During my time on the project, I have developed several features, including TabBar and Master Password, and I am owner and developer of two plugins: Tab Manager, and Flash Cookie Manager. I have also collaborated with the QPDFView software project, where I wrote parts such as the Bookmarks Dock and multi-threaded search feature. Additionally, I have created bidiTeXmaker which is a modified version of TeXmaker that makes it more suitable for Persian users. Many mathematics faculties in the country installed bidiTeXmaker on their workshop computers for years.
