With over 20 years of experiences in software development, I focus on software design and development of web applications. I'm especially experienced in Java server application stacks with Spring/Hibernate/MySQL. I'm also proficient with Node.js server with GraphQL API and Javascript front end with Vue.js. I have also used Apache, PHP, and Python for web servers. I'm well rounded in enterprise software with a range of workflow, rules, and security technologies. I'm also good at big data analysis with MongoDB, ElasticSearch, Hadoop/Spark, and machine learning technologies.
I had worked for software companies in the US for 15 years. Now I'm a freelancer working from China. I'm glad to provide services also on software platform architecture, software integration, software troubleshooting and maintenance.
