Catalina Marketing Solutions Architect.

Confidential is a dominant global leader in behavior-based marketing solutions leveraging actual shopper purchase behavior to reach the right consumer at the right time with the right message - wherever and whenever consumer products are sold.

• Confidential The Company decided to build their next generation application framework in Java/J2EE, with the intent of building their coupon based applications in an agile manner. The framework was developed using Java, Spring, OSGi, Hibernate and JMX as the primary technologies.
• The framework core components are the Command Framework and the Triggering engine a domain specific rule engine . The command framework is a light weight transactional framework the key idea being not to use a heavyweight rollback of transactions but rather use compensating action based on the command pattern. The triggering rules are implemented as parametric event handlers which form a directed acyclic graphs. The handlers are sorted based on their topological id assigned to them during the award/coupon construction phase. Each graph represents an award/coupon which triggers the printing of a coupon/patient information. The applications for the various retailers/pharmacies could be configured using Spring's IoC. The fundamental design patterns are the Template, Strategy and Dependency Injection.
• Another key component of the framework is the ThreadManager that hides the complexity of the Java Concurrency package to the developers along with providing monitoring of threads
• The application was architected to run as a cluster. The cluster can now scale to handle hundreds of transactions per second.

• The product uses the FlexConnect framework to deliver coupons in store based on the customers purchasing behavior. The project followed a variant of the agile development methodology based on Behavior Driven Development. A combination of open source tools like, CruiseControl continuous integration , Maven build management , Subversion/Subclipse change management , Trac issue tracking , Checkstyle coding style , Clover code coverage , etc. were used. BDD was successfully used to deliver an almost bug free code base to SQA, even under the constraint of using offshore developers for a complex piece of functionality.
• Role: Java Architect. Owned all key architectural decisions. Assisted the client in adopting Java/J2EE as the technology of choice. This entailed training the team in Java and related technologies. Also helped co-ordinate an offshore team in India. Worked closely with the project manager in streamlining the development process based on XP . Introduced Behavior Driven development within the company and successfully executed a 75 man month project with almost no bugs using an offshore team.

• This is a platform which gives the user usually from sales the ability to conceive, create, define, target, design, analyze, manage and control campaigns in a multi-channel environment. The system outputs all the qualified customer ids that meet a certain criteria in order to optimize the manufacturers spending's on a given marketing campaign. The system looks back at purchase history identifying trends, opportunities to help in create a customer ID list that can be sent to the store to print coupons the next time he/she comes in based on his shopping behavior. The application was deployed on Heroku. The language used for the backend and the REST API was Python and for the frontend Javascript was chosen. Logging was done using Mongodb.
• Role: Was in charge of introducing Behavior Driven Development to the team and helping them with their software development process. Also was instrumental in building a dashboard for real-time monitoring of the application parameters in production. The tools used for this purpose were Graphite, Statsd, Whisper and Carbon.

• A Fortune 100 company that provides a wide range of investment products to help people plan for and live comfortably through retirement.
• Projects Advisory Management System: The system is intended to advice and manages client accounts of the Wealth management group of TIAA-CREF. The application provides advice and managed account solutions to cater to the savings goal of the client, in compliance with provider's plan and product rules.
• The system is a standard J2EE application, following a layered and MVC architecture. The application is deployed on Weblogic 8.1 and uses Oracle 9i for its persistence. The O/R mapping is done using Hibernate. Struts was the UI framework of choice.
• Primary Responsibility: Architect solution and provide technical leadership.

Senior J2EE Architect

• Projects Epiplex 5.0: Epiplex platform is a process layer on existing enterprise infrastructure, that include ERP, CRM, Workflow, data bases, legacy applications, e-business applications, and internal product development, deployment and implementation infrastructure. The process platform is based upon an organic, self-improving and a full life-cycle process. Current iteration will focus on the business process improvement component the Analyzer. This component will analyze a given business process and provide reports on the efficiency, time taken, optimal unit process steps etc. Architectural challenges include building a highly scalable component that can process gigabytes of data on an hourly basis captured from around 10000 users. The high scalability was achieved using JBossMQ cluster and by processing the JMS messages on separate JVMs on individual processors. A finite state machine generator was used to identify the unit processes.
• Primary responsibilities: Architect solution and lead the prototyping team.
• Technologies: J2EE JMS, JSP, EJB , Ilog Rule Engine, Oracle 9i, JBoss Cluster, Apache

Senior Technical Architect

Projects

• Project - Enterprise Rate Manager: ERM enables a bank to produce its own proprietary market rate feed reflecting their trader's views in real time. It is designed to protect the traders, while also giving control and visibility to the prices they are making and distributing to the market. ERM provides for the input and manipulation of market data in order to provide banks with derived prices for use by down-stream auto-dealing systems. It sources data from electronic feeds available via the Reuters Triarch platform, JMS etc. It also publishes the output via Reuters Triarch market data platform and JMS.
• The real time performance required by the application was achieved via the ERM server, which built on a multi-threaded pipe and filter architecture. The architecture allows a trader to define a pipeline of processing activity via XML rulesets. The rulesets also provide the plumbing or pipes necessary to transfer data from one calculator which form the filters to the other.
