At Voicent, besides back-end work, my tasks involved bootstrapping the entire website, along with the Wordpress blogs and Ecommerce portion. The entire process of redesigning their 5000+ pages took me a month. I also inserted Rich Snippets and updated their meta tags, and wrote blog posts for SEO.
Photoshop and photo manipulation for web content played a huge role when I was working on the website's front-end. This project allowed me to brush up on my photography and photoshopping skills. As a result, I was able to update many of the old images with newer, modern images.
Though the front-end development work was on me, for back-end I worked on a 4-person team. I helped optimize the rapid sending/retrieval of thousands of queries to ApacheDB that came from the software program's threads. This involved extensive testing, and allowed us to increase the maximum number of program threads from 1000 to over 10,000. Those program threads were for handling a client's simultaneous phone calls. This meant a large call center client could have 10,000 phone lines instead of 1000 phone lines.
