    Hello, everyone! My name is Sergey. I am living in Belgrade, Serbia. I have 10 years of experience in software development. My skills: ✓ C++ ✓ Qt ✓ QML ✓ QSS ✓ PowerShell ✓ Multithreading, memory management ✓ GoF Design Patterns, SOLID ✓ Unit tests ✓ UI/UX design ✓ Data processing ✓ Web-scraping ✓ JSON, XML ✓ Arduino (mostly hobby) Tools and libraries I am working with: ✓ Qt ✓ STL ✓ Doxygen ✓ SVN ✓ Git ✓ Gitlab Benefits you get working with me: ✓ DOCUMENTATION: I am using a pseudocode approach during writing the code so that any developer supporting my code might easily understand what were my intentions about during writing it. ✓ WARRANTY: I understand that nobody can fully test an application in 1-2 days so that during 1 month after finishing the project you can feel free to contact me if you find any bugs and I will fix them without any payment. ✓ FREE FEATURE REQUEST: Sometimes customers forget to describe some tiny feature in the project task. During 1 month after finishing the project you can ask me to add some feature that was not described in the initial task if its development won't take more than 8 additional hours. Only 1 free feature is allowed. Have any questions? Want to discuss your project? Or just want to get an advice? Feel free to contact me at any time! ;)

    I started coding for fun at a very young age, self teaching myself across a broad range of technologies until the point I could do commercial software development. From there, 20+ years of career guarantee the quality of my services, across a broad range of programming languages, platforms, frameworks and methodologies. I feel confident that if you have a requirement, I can design it and build it in a cost-effective way to your satisfaction, either as a solo freelancer or as part of a team. I welcome the opportunity to talk to you about any project requirement and the possibility of working together to build it in an efficient, standards-compliant, and elegant way.
