About the Author

Sohail Salehi is a full stack web developer who is constantly seeking creative solutions for complex problems. He believes that what has been taught as universalities should be considered as a basic stepping stone to real-life challenges. They cannot be used as practical solutions. He learned that a one-size-fits-all solution does not work in the IT world. Every business, every coding challenge, and every environment setup has its own signature and requires some tweaking on basic principals to make sure that it receives a reliable cost-effective solution.

When he is not staring at his computer screen, he is watching sunsets and sunrises, swimming and surfing in the ocean, and putting his subconscious mind at work by asking creative questions while facing life's ups and downs on a daily basis.

I would like to thank the Packt Publishing team for being supportive at all times and also being patient with me at the times I've gone wild and updated the book contents over and over again.
