Catalina Marketing Solutions Architect.

Catalina Marketing; http://www.catalinamarketing.com 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.

FlexConnect Framework –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 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 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.

FlexAwards -- 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.

Team size: 30

Catalina Distribution System (CDS) -- CDS replaced the legacy Order Distribution System ODM). ODM was a mission critical operational system for Catalina as it distributes the business rules on a nightly basis for Catalina coupon printing system in about 45000 stores nationwide and another 10000 system worldwide. CDS was designed to be highly modular offer distribution engine and had 2 major goals – one was to use MPEG compression to reduce network usage and ink usage and the other was to fulfill the SLAs that ODM was failing to fulfill. CDS will expose a service interface that will allows clients submit data and the endpoint address to which the data needed to be delivered to. CDS used Mongodb for persistence.

Role: Architect for a team of 10

Cameo – 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.

8/2003 – 3/2004 Integral http://www.integral.com 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.
