Over the last few years, I have developed a wide range of websites using Joomla, Wordpress, Virtuemart & other Shopping-cart systems, HTML, PHP, Dreamweaver and MySQL including sites for startup companies and small businesses. I am very flexible with my work routines, I have a firm knowledge of different types of technologies used in the field of website development and can implement my skills in an efficient way as required. I am seeking opportunities to build websites from the ground up for you or your business
I have been working for about 8 years in the IT field with small and enterprise systems. Earned solid experience with Windows and Linux systems. Mostly have hands-on experience with Linux (Debian/RH-based), all the main server distros. Started from systems maintenance/administration, then SA procedures automation, and finally currently is in development field. This path let me gain lots of experience with different software, which lets create/troubleshoot/maintain services quickly. Have experience developing/setting up different APIs/Backends. Python development (XMLRPC, XML processing, SOAP, REST, django, django-REST), NodeJS (Express, winston, cluster, databases), experience with Parallels products (usage & maintaining of POA, PBA, PVC). Parallels APS packages development: APS 1.2 & APS 2.0.
I'm a backend developer but also have strong front-end skills. My goal is to be a full-stack developer. I like to make applications that are simple, but powerful. I have more than 12 years work experience on IT , software, web area. I worked in Huawei and Cisco as a senior developer and a project manager before I became a freelancer. And now I have a small but great team. We build web, restful api, ios and android apps based on html5. We have built several projects from scratch and made them to get the investment. I used to worked in New York City to help a startup company to build the backend service.
