Olga Filipova was born in Ukraine, in Kyiv. She grew up in a family of physicists, scientists, and professors. She studied system analysis at the National University of Ukraine Kyiv Polytechnic Institute. At the age of 20, she moved to Portugal where she did her bachelor's and master's degrees in computer science in the University of Coimbra. During her studies, she participated in research and development of European projects and became an assistant teacher of operating systems and computer graphics. After obtaining her master's degree, she started to work at Feedzai. At that time, it was a small team of four who developed a product from scratch, and now it is one of the most successful Portuguese startups. At some point, her main responsibility became to develop a library written in JavaScript whose purpose was to bring data from the engine to the web interface. This marked Olga's main direction in techâweb development. At the same time, she continued her teaching practice in a course of professional web development in the local professional education center in Coimbra.
In 2013, along with her brother and her husband, she started an educational project based in Ukraine. This project's name is EdEra and it has grown from a small platform of online courses into a big player in the Ukrainian educational system. Currently, EdEra is pointing in an the international direction and preparing an awesome online course about IT. Don't miss it!
In 2014, Olga, with her husband and daughter, moved from Portugal to Berlin, where she started working at Meetrics as a frontend engineer, and after a year she became the lead of an amazing team of frontend software developers.
Olga is happily married to an awesome guy called Rui, who is also a software engineer. Rui studied with Olga at the University of Coimbra and worked with her at Feedzai. Olga has a smart and beautiful daughter called Taissa, a fluffy cat called Patusca, and two fluffiest chinchillas called Barabashka and Cheburashka.

I am grateful to Packt Publishing for offering me the possibility to write this book. You are great and so is your team. Thank you Divij, Chaitanya, Prajakta, and the whole Packt team for being awesome and supporting me through all this journey in such a friendly and warm way.
Quality is something that is difficult to achieve when working on something on your own. Thank you, Packt team, you've been awesome. And a big special gratitude goes to Romania, to Bogdan, who thoroughly reviewed the book, ran all the code snippets, tests, and lint. Bogdan's attention to even the most tiny details is astonishing. The book was rewritten after Bogdan's comments, and it became so much cleaner. Thank you very much, Bogdan and Alex, for the recommendation.
Time. Support. Love. When you have these three things you are happy and any challenge in the world can scare you. When you have these three things you know that you are capable of everything. When you have these three things you have power. But you can never have these things alone. That is why you must be eternally grateful to those who provide time, support, and love to you.
That is why my big thanks goes to my company where I am currently workingâMeetrics. Meetrics provided me with time to write the book. They trusted me and allowed me to use a fraction of my working time for writing the book. Thank you very much!
I want to thank to all my friends and colleagues who supported me during this journey. Every time I come to Meetrics my team asks me how the book is going. Every time we're going to Portugal or Ukraine, our friends and family ask. Every day my friends from Berlin ask me how is it going. Thank you, people, you are awesome! Thank you, EdEra team, for being amazing and postponing important tasks because of my book.
I would love to express gratitude to my parents for educating me with so much love that I know that I am capable of anything. I know that I will not fail. Thank you for all your love and support. Thank you for giving me this confidence in myself. I want to thank to my lovely daughter, whose love and help keeps me going and continuing what I'm doing, knowing that all this is not for nothing. I want to thank to my brother for all the fun we share even and mostly while we're working.
And I want to address a special thanks with love to my husband. Along this writing journey Rui has given me time, support, and love. Rui did everything at home so I could have all the time for writing. Rui felt every slight change in my mood and provided support during all of them so I could feel comfortable again and write. If I would stay up the whole night writing and needed someone to be nearby, Rui would stay up the whole night. For every chapter in the book, Rui was the first person to review them. This was invaluable feedback. Rui gave me chapters back full of corrections and I felt sad. But then he would say something like: Oh my god, Olga, this chapter is amazing! I understood everything! I am looking forward for the next chapter to see what's next! When someone who you love very much tells you this, you just want to move on and continue your amazing writing. Thank you very much for this!
