Client: Verizon
Role: Developer
Description: Documents were provided till AWS via Block Ledger which the client already knew but took it a step further and written code for Deep integration into AI, All the Criteria of the Project were met on Par with client's expectations such as OZEKING tool given for SMS, )documents -> Block Ledger), AWS given through documentation as touching AWS itself is considered as a very risky proposal as without properly route channels many instances gets created. Responsibilities:
• Coded for Deep Integration into AI, DLT Ledgers were Perfectly Integrated

Client: Verizon
Role: Developer
Description: UUNet has some Perl scripts (report screens) which needed to be migrated to Struts 2 for simple UI, so as part of this project we had to first understand what the existing Perl programs are doing and consequently convert the Perl programs to Struts 2. VDDS gets the orders from OTS to COM, So for OTS dependency we are removing the tables. Databases are being changed from Sybase to PostgreSQL, so we had to set the OTS Decommission Flag to true for PostgreSQL and false for Sybase, the classes/methods/tables were identified, and the changes were made. The existing web services were also tested as they also insert the data in the tables and were tested whether they were impacting the tables. It talks with SNM to find out which is the gateway it is provisioned for the customer and gets the details such as Quality, Quantity required from the customer and after that readies the template and gives it to SNM for taking it over from there for the given network and for the specific customer requirements. VDDS gets the order from PC, PQ, OM+ etc with IPSM and SNM it will do the provisioning for the different devices, IPSM will take layer3 info from VDDS and send it to IP Manager to get the required IP Addresses and all these will be sent to SNM. SNMIP, SNM2 - Both talk with the VzB Network (same database), Corba interface is for talking with VDDS, Web GOA etc. SNMIP, SNM2 also talk with each other using Corba interfaces Responsibilities:
• Converted Perl Scripts to Java for Struts2

Worked on below PoC’s in between the project:
Transliterate: As Tandem accepts only English letters the send and receive to the VZ would be done using a small utility which would convert forth and back the letters typed in other native/ regional languages, this was used in E-Connect and the application displays all its fields in the native languages but while going to the VZ server they are transliterated to English characters. ATP2JSF: Legacy applications running in Netscape browsers using ATP technologies have to be migrated as VZ is planning to move out from tandem thereby to move out of the legacy technologies so a POC was developed for The TreeNode migration of agent end points and their data to JSF form. Proposal for Scala: Run sample D2B programs in Scala to identify the differences and the advantages of using it over java.
JBoss in Tandem: A POC was developed to show that tandem could hold a nonstop Jboss with the help of Java Infrastructure and QA application was successfully ported in JBoss.
