Hi everyone, I am Zhongshi Xi, I am a software engineer in Nascent at this moment. I started as DevOps engineer for a year and 4 months where I developed automated deployment solutions using Docker, Ansible, Jenkins. Then I became data engineer where I created ETL using Hadoop, Spark and Scala in 6 months. After that I joined Nascent where I am doing full-stack development. It has been 5 months now and I am still learning a lot related to architectural design, front-end tech (HTML, React, JSX, CSS, etc) and back-end tech (NodeJs, ExpressJs, Redis, MongoDB, etc ), I have a lot to learn and I will keep learning. I am still a Junior developer but I will learn how to learn so I can learn efficiently. I will spend more time to learn & practice so I can know in depth. I do not believe full-stack dev is jack of all trade and master of none. With the right attitude, patience and effort, full-stack dev is jack of all trade and master of more than some. It has been a joyful experience since I joined this community where I ask questions and people answer them with their unique effort. I believe I can learn a lot from the community and I am willing to contribute back to the community.
