I have been into the industry for around 8 years and have been successfully growing with my clientele month by month, year by year.
Talking about my career graph, I actually started as a web designer and gradually learned coding to give it breath. Until 2011 I was able to explore nitty gritty of web applications. But the biggest challenge I encountered was all about the business side of online applications. It was indeed bigger picture missing from my syllabus of study. I started making my hands dirty on marketing side of this ever growing industry.
Now, I talk designs as usability & user experience, applications as features and SEO as the broader spectrum of business where three aspects ranking, traffic and conversion are defined as business goals.
