I have a lot of skills and related experience in 3 aspects.
1 is for SEO and SEM. I have been working as a SEOer for 2 years, dedicated to a start-up company. I have done SEO for nearly 10 websites and not only the SEO, but also the whole SEM thing like Google Adsense, Google Adwords and even affiliate marketing.
2 is for computer engineering. I build some websites using Python, Django, MySQL, HTML, CSS and Twitter API all by myself. Data scraping is also used.
3 is for design. I major in industrial design in my university and I have done some work in Graphic Design with Photoshop, Product Design with Rhino and Keyshot, and Engineering with AutoCAD.
