I am not new to the world of coding. I have spent over 30,000 hours programming. By choosing me, you are choosing an experienced programmer. If you are an agency and you need someone who knows what he is doing and is going to stick around like someone directly hired, just without employment overhead, consider me.

Given current disarray once mighty osCommerce is in, many merchants decide to switch. Some go for OpenCart. This project, was first about enhancement of osCommerce, but after a few months merchant decided to switch to another platform altogether. OpenCart was eventually chosen. Switch was a complex one due to many add-ons. Some were purchased, some were written by me. Also, there was a need to transfer database, which was accomplished as well. If you are on osCommerce and thinking about switch, think experience, think me.
