    I am fast learner with strong math, analysis and problem solving skills. Being a passionate programmer while studying sound engineering and acoustics made me fell in love with DSP. Since then I've developed many apps involving beamforming and sound separation, 3D binauralisation, speech intelligibility tests, hearing impairment diagnostics, hearing aid fitting and comparison, learning to speak language through microphone feedback, media transcoding and streaming, VOIP, call center solutions, voice & instrument modeling and analysis, yet sound is not my only area of interest. I like coding video/graphics, games, embedded and more general computing as a self-taught hobbyist. I'm familiar with C, C++, Octave/Matlab, C#, Java, Python, PHP, Javascript, SQL but sticking with first three most of time. Worked with technologies like Qt, Vulkan, CUDA, OpenGL, GLSL, OpenAL, Direct3D, DirectX, WebKit, WebEngine, FFmpeg, winmm, VST, IAX, JNI, Atmel AVR, ESP32. Always open to learn new things and make the world a better place.

    Main specialization – C++ (STL/MFC, QT, PostgreSQL - on board). 15+ years of experience. Open to start new project on following tech stack: 1. Web: Python (any web framework), React, React-Admin, PostgreSQL, Dockers, Amazon Web Services, FreeSwitch. 2. Desktop, client/server solutions: C++, QT Framework. Last few years work with C++ on Debian (PostgreSQL, ncurses, thermal printer). Recently extensively switched to QT framework (Music Score scanning software). Had a chance to use general logic experience to lead engagement projects in completely unknown for me areas like Lotus Notes/Domino, software for greenhouse heating systems construction, some projects on Delphi. Searching clients for cooperation to outsource software products development. My formula: Scope of Work – Time – Budget (W-T-B). W-T-B key principles: - establish project required development process; - define milestones; - provide “access points” for process control from a client side; - self-documented code; - quality assurance; - support.

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.
