CREF.

A framework was designed and delivered to TIAA-CREF which is currently in

version 2.0 after changes recommended by Architects. Deployed as a REST

service. Any application that needs an outbound call can use the framework

by providing key values and if the application requires an inbound call,

the same framework can be configured at DocuSign.

requires mainframe knowledge. Initiative started to use "IBM DB2 Connect"

by various Webapp to connect to the mainframe database. Each application

has been updated to incorporate the changes but any change at database

setup required all applications to be updated.

The framework DB2 Connect Services is developed using REST API and Spring

Integration. It has the ability to connect to multiple database based on

the service call. Spring integration redirects the execution using the

input data. Framework version 2.5 is currently in production region and

used by multiple applications.

METLIFE - USA

Role: Framework developer

Jun 2013 to Nov 2013

Project: ACE - Self-service

Description: The Ace application had multiple development and testing

environments which required dedicated resources to monitor the batch jobs,

file routing and environment outages. Any failures had to be manually

checked and restarted impacting the performance of developers and also the

turnaround time was more impacting testing efforts.

The self-service application was developed to overcome the above issues.

This was also part of the MS-dissertation; now deployed on the Metlife

development and testing environments.

The automated monitoring module watches the logs and applications for

any issues/outages. If any, an alert is sent to group as mobile alert.

Developed using the Talend jobs & Talend ESB.

The file routing module routes files between different informatica and

batch. If files not received on time, alert sent to group as mobile.

Developed using the Talend jobs & Talend ESB.

The mobile application provides a remote interface to monitor &

trigger jobs manually. Also receives the alerts from above jobs. Developed

using the Android.

Responsibilities:

. Involved in preparing and finalizing the requirements.

. End to End ownership for the design and development of the framework

. Developed the Talend Jobs for monitoring
