Cloud Solutions Architect
RHI.
Lead Enrichment:
RHI wants to enrich job leads scrapped from the web to provide more value to field in converting
them to job orders. In addition, track those lead conversions and also provide more insight into the processes that help in converting those jobs leads. The application was built wholly on AWS
using SQS, DynamoDB, Java on Docker/ECS, CloudWatch and S3.
Responsibilities:
• Defined Application Architecture/Application Design based on AWS resources after
multiple POCs using multiple different approaches and technologies. This became the template architecture/design template for multiple projects (internal and external).
• Defined messaging based integration architecture for the processing flow with clearly
defined functions (with a micro-service intent) that allows for easy deployment and horizontal scalability.
• Within a short-time, coded all components required for Release 1.0 with Java and AWS
SDK, with TDD and CI. The system processes about 100k messages in about an hour,
adding extensive business value.
• The components are templated Java programs (running on Docker/ECS), which
performed a function as defined by a configuration file.
• Each component was designed and developed to process messages (SQS) and data
persistence operations (DynamoDB) and other assorted functions.
• Used Python (boto3) with AWS-SDK to implement system tasks including API based
interaction with SQS, DynamoDB and CloudWatch Logs
• Used Maven/Git/Jenkins as the scm/build infrastructure.
• Intellij Idea/Pycharm was used as the development IDE.

Micro-Services migration:
VCE has a monolithic CPQ (used to configure Converged-Infrastructure solutions AKA VBlocks)
application built on old-world stack and this project's intention is to update the stack and in the process, transition to a SOA based application platform, using CI, TDD and other Agile practices.
Responsibilities:
• Worked to identify application bottlenecks and profile SQL queries, after the application
was not responsive enough for user needs.
• Provided guidance as well implementation expertise to use distributed caching as a way
to lessen the hits on DB and provide better application performance, using Pivotal
Gemfire distributed cache. This brought down system latency drastically.
• Gemfire distributed cache was predominantly used as a business tier cache, using
@Cacheable and related annotations via spring-cache/spring data frameworks. The
move towards using Gemfire as a write-behind but read through cache for transactional
data was a WIP. Also used listeners to refresh the cache dynamically, which would sync
the server cache with client caches
• Gemfire distributed cache was run in a simple mater-slave cluster mode. Also used
'pulse' for monitoring as well as metrics.
• Using TDD, implemented various business functionalities as REST services, using a Java
(Springm MVC) based stack
• Using AngularJS, implemented various UI features to consume the REST services and provide end-user functionality.
• Worked as part of the scrum team to design and develop various other functionalities
and guidance to business on future product development.
• Used Java/Spring/Spring-DataJPA/JUnit/ as well as AngularJS to deliver the above
functions.
• Used PMD/FindBugs/EclEmma as well as sonar for code coverage/best practices in coding.
• Used Python for various prototyping and system tasks.
• Used Maven/SVN/Jenkins as the scm/build infrastructure.
• Intellij Idea as well as STS was used as the development IDE.

Sonic-MQ/ESB to IBM-MQ Migration:
The migration effort involved moving 48+ applications (Java/Non-Java) from Sonic-MQ to IBM-
MQ with Apache Camel, by way of using a custom java library (in place of product specific JMS drivers) and an open-LDAP based external configuration service. All of the Sonic Bus (EIP on ESB) functionality was ported to use Apache Camel on Tomcat server. All of this was delivered within a span of 9 months and business executives were elated on hitting the target well within
the deadline and also of huge curb in license expenditure.
Responsibilities:
• Worked as the lead of a scrum team to design and deliver a Messaging-Library, which
acted as an intercept layer between actual JMS driver libraries and JMS Message
consuming applications. This Messaging-Library integrated with configuration service as
well as Integration Test facilities to provide seamless migration between different JMS
Brokers in the future.
• Using Python, worked as the sole developer to extract destination and route information
from Sonic-MQ specific constructs to document a D3 diagram of all destinations and routes. This provided the most value later in the project when trying to debug message
gone missing scenarios.
• Worked as part of the scrum team to design and develop Apache Camel routes in place of existing Sonic ESB CBRs and similar constructs and to use IBM MQ destinations
• Worked as a liaison for interacting with various application teams/owners for migrating
their applications off Sonic-MQ to IBM-MQ by way of Messaging-Library. Most of the applications were legacy (at least 10 years old).
• Quickly came up to speed on OpenLDAP based Config Service and supported it through
production deploy of various migrated applications.
• Used Java/Spring/Spring-JMS/JPA/JUnit/Apache-Camel to deliver the above
functions.
• Used PMD/FindBugs/EclEmma as well as sonar for code coverage/best practices in coding.
• Used Python for Configuration data parsing as well interact with IBM Brokers (IBM JMS specific syntax)

DSP is the NG service framework to support the industrial internet. DSP is built on a OSGi
(Apache Karaf) based services framework extensively using the spring framework. It provides
out-of-the box functionality for system services and envisioned to serve as the base building
block for multiple domain specific solutions.
Responsibilities:
• Designed and developed restful services (jax-rs/cxf), domain (JPA) as well the data
model (Oracle) for a reporting solution for the airline vertical. Used MongoDB as an in-
memory store for storing user profile/credentials for a security service.
• Proposed TDD approach as a means for testing OSGi based applications which are not
very amenable to TDD because of the intrinsic nature of OSGi container.
• Fixed numerous bugs/multiple refactorings for a play2.0 based presentation layer
framework used to demo the viability of the platform.
• Developed/delivered an installation/upgrade utility using python 2.7 within a very
short period of time.
• Helped in the development of multiple miscellaneous features in support of product
push to production including automating test infrastructure using expect4j.
• Mentored multiple co-workers in design and development of new features/TDD/Agile
development methodologies
• Evaluated one-click-deploy to cloud using JClouds with AWS/OpenStack as well as a
hybrid cloud approach.
• Used Java/Spring/Spring-JPA over OSGi to code back-end services. Minimal XSD was
used to define payload interfaces. Json was used as the interchange format.
• Used Mockito/spock/JUnit/Pax-Exam to code on a TDD approach.
• Used PMD/FindBugs as well as sonar for code coverage/best practices in coding.
• Used Bamboo/Maven/SVN as the build infrastructure.

Apache Karaf, Spring 3.1, MongoDB, JDK6, JUnit, Mockito, PMD, Pax-Exam, OSGi, Logback,
XSD/XML/XSLT, python 27/3.0, expect4j, Intellij Idea 10.5, Jetty, HSql, Oracle, Hibernate,

V.Me
V.me is the next generation payments platform that essentially provides capabilities similar to PayPal. V.me is built on a rest based web services framework extensively using the spring
framework. It integrates extensively with multiple internal services to provide all payment
transaction services. The software stack uses Ruby/Spring/tcServer and the hardware stack is
based on a VBlock infrastructure with Gemfire Vfabric being used for caching.
Responsibilities:
• Proposed the technical debt concept and feature velocity to contrast original home grown
framework which used SI as a way to build application logic, which ultimately resulted
in the framework being refactored to used jax-rs reference implementation.
• Developed the domain model and related facilities for an already existing web-service
which provides Alerts functionality.
• Lead the design and development of CSR functionality based on Spring web-services
which provides a service interface for Siebel based applications to consume v.me services
for customer support.
• Helped in the development of multiple miscellaneous features in support of product
push to production including fixing penetration test findings based on significant attack
vectors.
• Mentored multiple co-workers in design and development of new features.
• Used Java/Spring/Spring Data to code back-end services. XSD was used to define
service contracts/payload interfaces. Json/XML was used as the interchange format.
• Used Mockito/spock/JUnit to code on a TDD approach.
• Used PMD/FindBugs as well as sonar for code coverage/best pratices in coding.
• Used Jenkins/Maven/SVN as the build infrastructure.
• Intellij Idea was used as the development IDE.
Environment:
Spring 3.1, Spring Data 2.0, Spring Integration 1.0, JDK6, JUnit, Mockito, PMD, Logback, XSD/
XML/XSLT, Intellij Idea 10.5, tcServer 6.0, HSql, Oracle, Hibernate, Maven, Subversion, scrum
Methodology with agile practices including TDD, pair programming and mandated code review.
