I'm a Software Engineer with 10+ years of industry experience in software platform development. I have worked on wide array of technologies among them PHP, Azure , HPC , Databases and Python is where my core strength lies. Colleagues know me as a team player, technically sound individual who can always be trusted to come up with a out of the box solution. It has been my firm belief that the organizations interest comes first, and I never try to impose my ideas on others. Instead, I spend a considerable of time understanding the business and the audience before suggesting solutions. The desire to start a course on udemy to share with people the issues I faced with Software so I can help cut the red tape for projects and help increase productivity
