Ravindra Kumar is an Android Engineer,A Computer Polyglot from Bengaluru, India. Android + WEB ♥'r, speaker, startup geek, open source junkie.

He has a strong interest in code quality, testing and automation - preferably all three together. Combining technical with soft skills, he also ventures into the realms of mentoring and article writing, He hates doing things manually, and hates to see src/test/java directories with Empty Example classes.

He believes that by working with legacy code, and improving it, he can make the world a better place. To his disappointment, the world does not seem to care all that much about his efforts.

He started as a Web Engineer who used to write lots of javascript, but after some time, looking for his real passion, he started his journey in mobile app development though Titanium, later he discovered the Android world. After getting some experience on such an awesome platform, he started a new adventure at a mobile company, where he led several projects for important Indian companies.

He is a pretty normal person – a husband, father of one loves cricket.
