Hello,
I have designed and developed many Ext Js based =-Java projects in software company so far. I have strong experience in backend with popular Java frameworks(Spring, Hibernate, Struts) and Liferay portal
Specially, I have experience in developing Sencha Ext JS from version 2.1 to 4.1 . One project was developed by Ext JS verion 2.1 for financial company in 2008 and project has been developed with Ext JS verion 4.1 for manufacturing company on Liferay portal. Recently I use Ext Js 6.0 for develop web application to manage asset in Spring Boot. I also worked with Ext brytum for gannt chart before.
Thus, I think my skills and experience can bring big value to your projects.
I hope to have a chance to become a part of team to bring your projects success
