All the famous brands and technologies do only one thing: let us build a website with the desired characteristics. Personally, I like the Yii and CodeIgniter frameworks, but it is not my skills are limited. If necessary I can create java scripts, develop API, pretty good design and create databases. My area of interest - a document workflow and automation. Also I try to keep abreast of modern technology and adhering to the "if you want, you can do anything."
