Management in web-development and products inventory

I built and maintained Milanlux.com from Aug,2008 to Oct,2012. I built it for my friend who has passion for high-end fashion. She has associates from Europe and Japan, so she can get designer handbags from there. I set up and designed the website, managed products inventory, updated company policies, resolved technical problems and maintained it for more than five years.Since it was start-up company, she has to spend several hundred dollars on advertising every month. I realized she can reduce the ad costs if her web site is promoted with keywords what most people were typing. So, I did search engine optimization, which was changing meta tags, titles, keywords in headline, page url, contents, inbound and outbound links.Gradually she was able to reduce advertisements,and reached the same traffic without any advertisement compared to the time she paid several hundreds dollars(more than $600) every month.  Followings are accomplished.

 Achieved on top lists in major search engines including Google, Yahoo, and Bing with SEO
 Saved advertisement costs 100%($25,000) with organic traffics
 Administered catalogue of web store items, legal documents in adherence to company policies
