    "We choose to go to the Moon [...] and do the other things, not because they are easy, but because they are hard" JFK I learn fast and have strong math, analysis and problem solving skills. I'm quite durable when facing a frustrating problems. Fixed and maintained projects written by others many times as well as built the working solutions from scratch myself. Daily Linux user. Can natively work on Mac or Windows as well. As a teenager I passionately coded games, map editors and simple utils in C++ and Python, but studying sound engineering and acoustics at the University got me really hooked into the highier math concepts, numerical computing and DSP in general. It introduced me to the Matlab/Octave as well. I quickly realized I can solve many practical real-life problems with my existing programming skills and all the new knowledge catalyzed my further development as a programmer greatly. During the following 20 years I worked on various projects and am constantly improving my skills and experience. Audio, DSP and physics-related utilities are not my only areas of expertize. I still like programming for video, graphics and games in mind, embedded hardware and more general computing as well. I love innovating and constantly work on my own inventions. Always open to learn new things and to make the world a better place. Let's do it together!

At a Glance: Qt

Introduced in 1995, Qt is a versatile web application framework for developing cross-platform applications and graphical user interfaces (GUIs). If you’re looking to build an app that provides a seamless user experience (UX) across any device or operating system, an experienced Qt developer can help you launch your project.
Qt developers can use C++ to build applications that emulate the native GUI of Windows, Android, iOS, OS X, and other popular operating systems and platforms. They can take you through the process of UX concept design and Qt hardware adaptation to create a single code base for building multi-platform software, with the look and feel of native applications. More than a GUI or widget toolkit, Qt also provides abstractions for SQL databases, SVG, network sockets, OpenGL, XML, and Unicode. With bindings like PyQt or Jambi, developers can integrate the framework with languages like Python or Java. Qt developers on Upwork can bring true cross-platform functionality to your applications.
