Thanks for visiting my profile. I am experienced passionate Web/Desktop Application developer. I mainly focus on building fast, accessible, intuitive and responsive solutions while developing various applications. I have got multifaceted experience in various languages and frameworks. Although there are plenty of languages and frameworks which I can rely on, my favorite language is Python as it is agile to develop and scale. I will always do my best to meet clients' requirements. I prefer original and challenging tasks such as Machine Learning, Data Science and Algorithm Design. I've got professional skill and experience in; - Python - C/C++, QT, Java, C# - Git/GitHub/BitBucket - Tensorflow, Keras - OpenCV - Django, Flask - Javascript, HTML5, CSS3, Bootstrap - Web Hosting (AWS, GoDaddy, Heroku, etc.) I live in Liaoning, China. I works mainly at CST(UTC +08:00) timezone but flexible on working time depending on the project. I am agile and flexible in English conversation. Regards.
