About the authors

Kamalmeet Singh got his first taste of programming at the age of 15, and he immediately fell in love with it. After getting his bachelor’s degree in information technology, he joined a start-up, and his love for Java programming grew further. After spending over 13 years in the IT industry and working in different companies, countries, and domains, Kamal has matured into an ace developer and a technical architect. The technologies he works with include cloud computing, machine learning, augmented reality, serverless applications, microservices, and more, but his first love is still Java.

I would like to thank my wife, Gundeep, who always encourages me to take up new challenges and brings out the best in me.
