    C++ / Qt / Qml developer

    Russia - Last active: 5 months ago - Tests: 2 - Portfolio: 2

    Hello, My name is Sergey Korostelyov. I'm a developer from Russia. I believe that my strongest qualities are analytical mental structure, ability to work fast and effectively and high work responsibility. I think the main things every developer and especially a freelancer must think of is how to meet client expectations and of course deadline. I'm honest and fair. In 2006 I've graduated from Kharkov National Aerocosmic University and gained bachelor of computer sciences degree. I have over 3 years of C++ development experience. Most of that time I was working for 2 large Ukrainian IT companies and as a result I have almost nothing to show in my portfolio as I've signed NDA. From 2014 I had a remote work for company which preffered using Qt to write crossplatform applications. Since that time I have developed crossplatform video capturing/recording application from scratch and delivered it to client. Also I've participated other small projects at this time. Below you can see the list of technologies, frameworks and skills I have experience on: C++: Standard library, STL, POSIX multithreading, POSIX networking SQL/PlSQL QML Shell scripting: bash, perl, awk, sed etc Frameworks: Qt, Boost IDE/Tools: Qt Creator, MS Visual Studio 2010/2012, VisualAssist X, Eclipse, XCode Version Control Systems: MKS, Accurev, git, SVN DBMS: Vista, Firebird, Oracle, MySql Bug tracker: SoftTest, Jira, Kanbanize OS: Linux, Windows, Android Thank you in advance for your time and consideration. Looking forward to work with you.

    Qt and C++ developer

    Ukraine - Last active: 09/15/2014 - Tests: 3 - Portfolio: 3

    Main specialization - digital signal processing (especially images) - Qt C++ (widgets) - developing of multi-threaded programs (QtConcurrent/QThread), deep understanding of SIGNAL-SLOT mechanism, event loops, event processing. Expirience with Qt 4 - over 2-3 years. Right now learning Qt 5 ( iOs, Android support was added etc). - C, pure C++ (a little STL, since Qt’s give a lot more functionality and has the best documentation, i ever seen) - have good knowledge of Linux (Ubuntu, KUbuntu), have strong grasp of bash scripting (wrote and supported automated regression tests for several projects) - familiar with with version control systems, have chosen git for it’s flexibility. - understand a little of x86 assembler In my free time i learn QML/Javascript and Qt 5 My works: - Developing cross-platform tool for removing noise from images with Non-local means method. The same method, as i learned later is used by OpenCV lib to remove noise. Denoising is done in worker thread, while GUI is in main thread. Right now program can denoise image in a single thread mode and in multi-threaded mode. After this was done, I started to accelerate algorithm with fast fourier transform. You can check it out and contribute to it’s development if it has picked your interest here - https://github.com/shadowfury/Image-denoising/t… Or check this youtube demo videos : http://www.youtube.com/watch?v=lEEZUWR7j5c and http://www.youtube.com/watch?v=nsv7VNr5E48 - Not long time ago, Qt 5 was released, so i began learning it’s new features within my own face detection project. The whole idea is to take webcam image and detect face there (not decided yet, should i use OpenCV or will try to implement it myself).

    Poland - Last active: 03/16/2012 - Tests: 9

    My goal is to deliver complete solutions in short time and bug-free in best possible way with focus on functionality and end-user experience. To do that, most time I use C++ with Qt Framework as most efficent tools for coding. It gives very fast, low resource demanding and native looking result on all supported platforms ( Windows 32/64, Linux 32/64, Mac OS X, Android, Windows CE, Symbian, MeeGo ) and let me focus on real task, not platform depending details. I have good professional experience in other programming languages like SQL, Java, C#, C, Delphi, Bash, PHP, JavaScript, basic or assembler ( x68, atmel, arm) too. I studied Computer Science at the Faculty of Mathematics, Informatics and Mechanics at Warsaw University. Now I'm 15 years of professional experience as a programmer and analyst.I worked on financial systems for brokeres and banks, ERP class software for Real Estate market, CAD systems and others.

    Experienced mobile apps and GUI developer for iOS & WPF

    Ukraine - Last active: 1 day ago - Tests: 8 - Portfolio: 4

    With 10 years of experience as a software engineer behind my back, my main area of expertise is the development of business applications for the mobile and desktop systems with the aid of the following technologies: - WPF/.NET Framework. This includes the creation of the composite applications with rich user interface, based on the MVVM pattern and the Prism library. - Objective-C/Cocoa Touch. This includes two years of experience as a lead iOS developer for a mobile app designed to run on iPhone/iPad as well as on all other major mobile platforms. - Qt. This includes the development of the C++ applications for Windows, OSX and Linux driven by the cross-platfofm Qt Toolkit with the aid of native WinAPI, Carbon/Cocoa or X11 code code when necessary. Over my years as a Qt developer I had to deal with no less than ~80% of the classes available in the toolkit, making myslef extremly comfortable with this technology. - Additionally, I have a solid technical background with the PDF format and document processing in general: converting various document formats to PDF, pre-press document processing.
