I have started my career path as a Java developer. At that time, all of my skill is around web development, but as you know, Java is not the best programming languages for web development. Therefore, I moved to Big data industry, and soon found that this is the most potential field I can improve myself. Later, I learnt nodejs for real-time processing. My achievement is chat module which can integrate with any platform. Big data usually comes with analyst. And I also became the data analyst with Python. I used IPython for wrangling and exploring dataset.
