Expert Java & .Net & Python Developer

I am a software engineer with 18 years of work experience and can use different framework technology and have strong knowledge of programming skills. 1. I have good knowledge of Java/J2EE, Servlet, JSP, JPA, Mybatis. And I am familiar with the springboot framework. Similarly, I am very familiar with the use of springcloud. From gateway to microservice, I can develop it independently. I usually use springboot to develop programs, then use docker to package products, and finally deploy through jenkins. 2. In terms of .net, I have experienced the history of changes from asp.net framework to asp.net core. Of course, I often use asp.net core to develop websites now, and I also often use orm such as dapper and ef core. 3. When it comes to python, using scrapy to develop web crawlers is one of my favorite things. If you don't allow to use a framework, it's no problem to develop one by myself from scratch. I also often use python in the Raspberry Pi to develop programs related to IoT devices, and I often deal with modbus and the MQTT. Then use flask to develop related api. 4. I have rich experience in the field of front-end development, and I have very good knowledge of multiple front-end languages and libraries(e.g. HTML/CSS, Javascript, JQuery, Vue.js, Angular, Angular.js). For UI frameworks like bootstrap, elementui, iviewui, I often use them. 5. I also familiar with databases(e.g. mysql, sql server, postgresql), web servers(e.g. IIS, Apache, Tomcat, Nginx), middleware like rabbitmq, redis and so on. 6. with the devops like CI/CD pipelines, I can deploy them independently. for the tools like jenkins, I have good knowledge of the job pipeline. And I can write the docker file by hand, from build the base image to deploy them to server.

"Yong Jun did a great job by completing and rework codes and fix issues created by the previous freelancers.. What took the previous devs a week to try to fix the issues(which they failed) , This project was a rush with a short timeline but took Young Jun 2 days to successfully fix what the previous dev cannot fix. He is very well qualified in .Net and Java. And Also he is able to catch up really quick on the requirements and always figure out the best and proper way/solution to code the logics. I personally recommend Yong Jun . No doubt I will be contacting Yong Jun again for future projects that is related to his expertise. Thank you very much Yong Jun."
