Web Applications Development

I usually work on developing backends and APIs for complex web applications, using either Java (JSF/Spring/Liferay) or PHP (Laravel framework). I build several systems from scratch, including Content Management Systems, reservation & payment solutions, etc.

Version control

I feel confident working with Git VCS, I've worked on integrating modules developed by different teams, performed code reviews and helped with Continuous Integration processes.

UI/UX

I've also worked on user-end of applications, creating thin clients for complex systems, developing site layouts in cooperation with artists and creating visual themes for various popular open-source software. I'm familiar with responsive web design principles and modern HTML5 and CSS3 standards.
