• Prototyped and Designed / Implemented / finally supported the client survey system / inspection report system.
• For every kind of License Survey every year (child care center space area, room numbers, teacher detail, kids age group detail, plans etc), and for inspection report processing:
• Designed and developed REST APIs to support different front-end modules/components. Implemented persistence layer to back-end data storage through Spring Boot, Spring Data JPA/ Hibernate, JPA 2, spring jdbctemplate, SQL/PLSQL, Maven, Jenkins, Full stack.
• Built system UI with Angular modules/components/forms/services(HTTPClient, RXJS), used JAX-RS, JSON, Reactive, Javascript, HTML5 & CSS3, Agile, DevOps, test case with Jasmine and protractor.
• Used Apache Kafka to passing data from Inspection Report into License System.
• Supported and enhanced ChildCare license management system (License Application, Renew, Revision, and license Monitoring) project in production (release CCLS2.0/3.0/4.0/…/10.0)
• (Full stack )Coded Front page by using JSF/html/css/javascript, and the middle tier with Spring MVC (JSF+Spring) service, and back end with iBATIS/myBATIS ORM and Oracle DB. Etc.
• Externally, the system is for a user to submit a childcare license application, get an application ID, view processing status and finally get the approved license. Also, for user to submit a license renew or revision application which will follow the similar workflow.
• Internally, the system is for government program advisor to check the application, sending inspector to site, processing the application by rules, then pass to manager to final review then to decide to issue or refuse the license, or pending on condition etc.
• Designed / Implemented / finally supported the SO system.
• This is for people to report an accident (serious occurrence) in the child care center or a home child care agent site. And government may send an inspector to make a report, program advisor to process the report and manager make decision.
• Prototyped and Designed / Implemented / finally supported the Unlicensed Complaint and Licensed Complaint project .
• These are for people to complain a child care center or a home child care agent for something unsatisfied.
• And user can track his complaint, while the government program adviser inspects this complaint, decide to punish or not by rules and finally manager to make decision.
• The SO and the Complaint system all are coded Front page by using JSF/html/css/javascript/jQuery, and the middle tier with Spring MVC (JSF+Spring) service, and back end with iBATIS/myBATIS ORM and Oracle DB. Etc.
• The three (License / SO / Complaint ) systems are actually closely linked together, e.g. from a license detail page, we can view all its history SOs or complaints and can go to any its SO or complaint page by click the link button. Also, we can go from SO to Licence or complaint etc…, we can view the linked summary.
• The whole process is strictly controlled by the user roles and the defined work flow engine.
• The system keeps track of all the approved staff information and site inspection records for future .

• Designed and developed JSF front end template/pages by business work flow.
• Integrated front JSF with Spring controller/component in the middle, and iBatis SQL Mapping in the back end.
• For all the systems, Designed and created Oracle DB tables, SP, triggers etc for data storage, including the general system type table for licence apply / licence renew / licence revidion / licence monitor /SO / complaint / etc, all the types. And for every type, linked many documents to the document table, file record table. Also, for every type, linked to the workflow table, object status table, general system status table, transaction-status-mapping table etc.
• And used JasperReport generating PDF/Excel documents (Inspection stage 1 and 2 report, Licence renew report, Licence revision report, Licence Monitering report, for DN and Hcca type licences respectively, supported by multiple languages).
