Started with mirc scripting, then created my own websites (I had 1500+ websites when it was 2005) and earned a lot of money with domain parking and google adsense. Since I was not so good with programming, I was asking help from other people. But as you probably guess, I had many many problems with programmers. Then, I decided to improve my programming skills. Finally, I realized that coding is the coolest thing in the world. I feel better when I help other people over the world. This is how I became freelancer programmer :) I love coding and ready to help you. - Web Scraping / Crawling - Data extraction - Data conversion - API Integration - Wordpress plugin less -
