EPCC Cabling is a mobile application that can call REST Services for login and other operations. Spring REST services are created with SSO (Single sign on) and OAuth2 so that user is not required to enter credentials every time to access services. Integrated LDAP (Lightweight Directory Access Protocol) with REST Services, On upon LDAP user sign on, oauth2 token will be generated and stored in a token store then granted access to mobile application to retrieve data from database as per the URL provided by REST services. Same token will be used to access other services as well with SSO functionality, upon user logout/token timeout; token will be removed from token store, so no longer user can able to access services. Upon accessing after logout/timeout, spring security returns invalid token. Spring data auditing also had done for all CRUD operations by mobile application

Leading team to develop jobs to migrate all the required tables one by one

EPCC Piping main features are activation, reservation and MIO (Material issue order), Cutting plan. Activation module is used in Material take-off phase which is a phase shared between engineering and procurement, which activates the buying process of an item. Reservation module allow user to reserve the materials prior to MIO. MIO module is useful for user to issue an MIO. With this module user can select the activation no, system and other filtering criteria and check whether MIO can able to issue or not (in the back end, system will calculate on hand quantity for each spool along with materials and no of spools issued per spool under the selected activation, no of spool to be issued). User can select or reselect materials, so back end system will calculate on hand quantity based on the selection and display the available material to issue MIO. If there is no stock, then system will pop up no available material to issue MIO. System is integrated with LDAP user to login and access the module with spring security, Oauth2 and SSO (Single sign on). Once user login in one system, they can able to access other systems without entering credentials.

The central addressing scheme (CAS) or PAYNOW allows the participating banks’ customers to link their bank account number (s) to an alias /proxy as relevant, such as mobile Number, NIRC, Unique Entity Number (“UEN”), to facilitate simpler transfers.

Technologies : STRUTS 2, Tiles, spring, Spring Batch, Spring ORM, Java 8, IBM WebSphere MQ, Jasper studio, Oracle 12c, REST API, SNMP
Responsibilities:

• Worked on PayNow web module for new bulk enquiry and registration.

• Worked on batch module for data preparation then created new job for new reports with jasper. Wrote complex queries for jasper reports from database connection.
• Worked with CAS Processor and IBM WebSphere MQ for Schema & basic field validation for proxies e.g. UEN, mobile number etc.Enquiry/Lookup/Registration Request from the bank is taken from the request queue and processed (Schema and basic field validation) then put it in the response queue for bank.

Implemented new producer and consumer for REST client for bulk processor
