Definition of Reputation Credits
I am a passionate software engineer, fascinated by information technology and its versatile software ecosystem. I have been working in the software field, especially in data engineering, for more than 9 years. For my near future career plan, I will keep learning more topics like service architecture at scale, advanced data engineering, machine learning-enhanced software models, and cloud architecture. At some point in the future, I wish I could be a software architect or a data architect to revolutionize the whole software model.
I have below experiences, but not limited to:
#Java #Scala #JavaScript #Python #Shell #Matlab #PHP #Spark #Hadoop #Glue #Athena #Kafka #Solr #Redis #MySQL #MSSQL #AWS #GCP #Git #Bootstrap #HTML/CSS #SpringBoot #PlayFramework #CodeIgniter #Tomcat #Jersey #Jetty
