The Recommender application was an n tier web based application which was used by the Sales team to decide upon a Storage technology from the Netapp portfolio which would be the correct fit for the customer requirements. Netapp had a wide range of Storage platforms and technologies which could be sold to customers and clients in order to satisfy their storage requirements. These platforms and technologies were Flash cache Flash Pool Flash Accel EF and Series etc. Each of these technologies performed well on some requirements for example performance and latency whereas performed poorly on some other requirements for example cost rack space etc. The goal of Recommender was to assign scores to these technologies and platforms based on the answers that were given by the customers to preselected questions that Recommender displayed. The technology or platform with the highest score was then presented to the customer as the recommended storage solution.

Responsibilities

• Responsible for the architecture design and development of the application. Led the design of the REST services which were hosted on a clustered WebLogic Server. Responsible for the creation of the data model and the object model on the server side.
• Contributed to the decision on the technology stack which was finally used. Responsible for laying out the initial structure of the project including Maven build scripts JPA entities and Spring Data JPA Repository interfaces.
• Helped and mentored other team members in the areas of the technologies which were used the best practices which had to be adopted and the low level design of the services which had to be implemented.
• Wrote and unit tested the JPA entities the DAOs and REST/Java services. Responsible for the creation and maintenance of the seed data which had to be inserted into the database tables for Recommender to work properly. The seed data dealt with the questions and possible answers which were shown to the user.
• Actively involved in Database related activities like creation and changes to the Oracle schema creation of sequences and the copying of schema and seed data between development staging and production environments. Responsible for maintaining the schema creation scripts and the data insert scripts in Perforce.
• Involved in the performance tuning of the Java services by using lazy loading features auto-wiring and creation of Database indexes.
• The presentation tier was developed using the Kony mobility platform. The presentation tier made use of the REST services to perform CRUD operations on the Database and provided a GUI for the user to interact with the data. Was responsible for interacting with the Kony development team and helping them troubleshoot issues.

Role Java Architect

The Webtag Resiliency project was basically concerned with providing the ability to failover to an application called Webtag. Webtag was a JEE application which was responsible for the distribution of reports written by analysts to various parties who were interested in viewing it. Since it was very critical that the interested parties got the reports on time and without disruptions hence it was essential that Webtag experience close to zero downtime. What was needed was the ability for a parallel running secondary Webtag instance to take over the processing from a primary Webtag instance which had failed suddenly. Since Webtag was deployed on Weblogic and used the file system and a database to store files and data respectively the goal was also to provide a secondary file system and database which could be used in case if the primary ones failed.

Responsibilities

• Authored an architecture document which proposed a way to provide transparent failover from a primary Webtag instance to a secondary Webtag instance which was running on a different application server and using a different file system and database.
• Designed and implemented a prototype as a proof of concept for the architecture. Conducted performance testing using the prototype.
• Responsible for creating a local development environment for the application by mocking up external stimuli.
• Responsible for the configuration and deployment of the application using a multi pool. The multi pool was configured for fail over in which the failover database server was continuously synched up with the primary database server using replication.
• Redesign and modification of the webtag application in order to provide failover capabilities to the entire webtag application. Redesign involved checkpointing the state of the application regularly to the database.
• Responsible for the introduction of the Spring framework JPA/Hibernate and Struts frameworks in the application. The earlier application used EJB 2.0 beans JSPs and Servlets.
• Created and configured Struts s struts.xml Spring s applicationContext.xml and JPA s persistence.xml file to configure the presentation middle and ORM tiers.
• Contributed to the support maintenance and bug fixing of the application while it was deployed in production.

The Voyager product was designed for the medical insurance companies and enabled them to submit claims information and get replies from the CMS Claims Management System which was managed by the US Government. Voyager was a three-tier web based application which used the MS SQL Server DBMS for its persistence needs. It had a presentation tier which was based on servlets and the middle tier used the Spring framework in order to harness middle tier services.

Responsibilities

• Responsible for reviewing the existing architecture of the application and recommending changes for improving the performance of the system.
• Establishing processes of code review and documentation in the project team.
• Experimented with using the READ COMMITTED SNAPSHOT isolation level in the MS SQL Server DB instead of READ COMMITTED. Implemented the READ COMMITTED SNAPSHOT isolation for the Voyager application.
• Made changes to the application so as to use optimistic concurrency for database access.
• Implementing best practices in the project like using Spring s declarative transactions event propagation and use of JPA/Hibernate along with Spring etc.
• Prototyping and exploration of the Fitnesse testing framework from the point of view of determining the suitability of the framework for the project.

This project was concerned with two chief deliverables a Creating a flexible reporting framework which any application in State Street could use to add reporting functionality b Conversion of existing reports based on Actuate to Jasper reports. The reporting framework used the open source Jasper Reporting libraries in order to satisfy report requests made by applications within State Street. The framework was designed for scalability performance and extensibility so that numerous applications in State Street could offload their reporting needs to this framework

Responsibilities

• Created and maintained Struts s struts.xml Spring s applicationContext.xml and JPA s persistence.xml file to configure the presentation middle and ORM tiers.
• Worked on an Android client which made use of the REST services exposed by the middle tier. The Android client used those services to query for status updates regarding report generation.
• Used the Jersey library to expose Java services on the middle tier as REST web services.
• Contributed substantially to the final architecture of the framework which was implemented. Responsible for converting the requirements which were obtained from the business analyst to a concrete technical design and documenting the architecture using the 4 1 model.
• Design and development of the web interface for the application. Designed and developed the entire stack along with rest of the team. JMeter was used to load test the web interface of the application.
• Designed the Database schema to persist the report scheduling information to an Oracle database.
• Annotated Java classes with JPA annotations in order to map those java classes to their corresponding tables in the database.
• Contributed to the design development and unit testing of the report generation choreographer of the application.
• Mentoring of junior developers in the team providing them technical guidance and solutions.
