CANOPI – Special Project

 

Technologies Used: HTML, JavaScript, JSP, Servlets, Java/J2EE, PLSQL, UNIX

 

Accomplishments:

 

  • Functional and technical consultant for CANOPI.
  • Migration and Inventory Update Tool Development. This tool is used by Support team to update/migrate inventory to manually progress failed Orders or Data corrections. Tool is built on JSP/Servlets and uses Cramer APIs (PL/SQL) for update. This tool also supports Bulk migration with the help of Unix Scripts.
  • Users require inventory reports as part of their network planning activities. Amdocs Cramer reports use Struts to provide the reports. ATT maintains CANOPI website (HTML, JavaScript, PLSQL, UNIX), which host custom reports.
  • Reports Development: I have been developing and maintaining this report website to automate most of the manual tasks done by users. It uses HTML, JavaScript and CGI scripts to generate and maintain HTML pages on UNIX server.PL/SQL Scripts are injected within Unix Scripts to generate the reports. Report generation is automated thru cron jobs.

v  Reports are transferred (SCP) to remote user servers for further processing.

v  Manages team of two coworkers on various Report development projects.

v  Automated Report Statistics Collection process, to track the performance and failures.

v  Automated Report Request and Customization process.

v  Works directly with client to understand the requirements of the report and designs the report generation automation.

v  Implemented Report failure alert System.

v  PL/SQL query optimization to improve report generation performance.

Associate Solution Designer (Java/J2EE Developer)

Client: Confidential 

 

Confidential  Cramer address configuration, planning and service fulfillment for all types of telecommunication services. Cramer is one of the core module of CANOPI build on JAVA/J2EE, PL/SQL Unix. Legacy CANOPI Application was badly coded, resulting in poor performance. Customizations were not easy and had always ended up with multiple failures. ATT and Amdocs had initiated Re-Architecture of application due to rise in usage of application. I had worked as associate Solution Designer (Java/J2EE Developer) for 2 years in this project
