Project: REX (Regulatory Extensions) | The system is described here: http://www.finra.org/industry/regulation-t-filingsParticipated in design and architecture of REX. Gathered and analyzed requirements, converting them to UML diagrams and TDD-based unit and integration tests. Implemented the system in Java 8, using the following technology stack:AWS SQS for retrieving the client extension request claimcheck (based on the 'Claimcheck' messaging patternREST API: Using the claimcheck, retrieve the client request payload via a web service call to the originating systemDrools decision tables: created these tables, based on the FINRA rules for different types of submissions ('REGT', '15c3', '4210'), and different other parameters, such as extension request reason codes, sequence (new request, amendment, or follow-on).Liquibase for tracking and managing the PostgreSQL database schema and tests data changes across releasesCucumber: used this framework for unit testing the business-facing parts of the application, which allowed the business representatives to review the testing strategy and implementation. Together with Junit tests for other parts of the application, maintained 90+ % test coverageAWS deployment: participated in building and deploying the application to the various AWS EC2/RDS environments (Development, QA, Customer Testing). Currently the application has successfully completed the customer testing and is about to be deployed to production)

Senior Java Developer / Tech LeadArchitected, designed and implemented through final release the Wiley SAP Transactions Reconciliation System. The system loads all the participating legacy systems and SAP data into its own database daily, and then runs the reconciliation logic to create reconciliation results and store them in the database. Created REST API for the Wiley SAP Transactions Reconciliation System, using Spring Boot ActuatorWrote all of the backend logic and the JavaFX front end, that gives the users a dashboard view of the daily reconciliation results, allowing to drill through to the failures, and see the detailed description of the errors, for further action. Developed functional and technical specifications for all the interfaces feeding SAP (WRICEFS):38 functional interfaces covering 63 integration points 25 systems integrated with SAP as part of R2 (second release)17 Enterprise systems, 1 cloud based application and 7 external systems29 inbound flows to SAP from enterprise systems34 outbound flows from SAP to enterprise systemsIntegration points categorized as 17 High, 23 Medium and 23 Low priorityImplemented the system in Java 8 with SpringBoot, Oracle, Tibco (data transformation and loading)Designed and created the Oracle Database, using the Oracle Data Modeler. Wrote the Reconciliation queries and stored procedures.

Created an integration test framework for verifying that the complex objects, uploaded to the Numerix Cross-Asset Server for calculations by various clients, are represented correctly on the server. This required deserializing JSON objects to Java domain objects, uploading them to the server via the various existing interfaces (direct Java CAS API, XML file submission, REST, and SOAP), downloading them back using the same APIs and asserting the exact deep matching. All tests, except for SOAP implemented in Java/JUnit, SOAP implemented in C#, in order to be able to share with some of the customers using C#. In the process, discovered and implemented many changes and refactorings to some tool-generated artifacts Created sample event listener code and documentation, requested by a customer, for all of the CAS topics and queuesFixed dozens of existing issues/bugs for production releases Technologies used: Java, Apache Camel, Apache Thrift, C#/Visual Studio for C# based integration tests

Worked on Mypublisher's e-commerce server application, built on the Apache OFBiz open-source framework. The application communicates with the MyPublisher client (downloadable from their web site), which creates photo books and uploads them to the commerce server for printing. The commerce server receives and stores the photo book files, provides customers with the ability to customize their finished books via HTML forms, creates orders, processes payments, and forwards the orders to our plant servers for printing. I was managing a two-developer team (myself included), using simplified Scrum methodology, and reporting to the CTO, to have achieved the following tasks:re- engineered the OFBIZ transaction and database connection pool components, which currently experience performance and availability issues under heavy load.re-engineered the file upload subsystem to improve performance by using the buffer pool to efficiently buffer and store the received file components (using Apache Commons object pooling and streaming file upload APIs)

Working on architecture and development of next-generation SelectMinds Corporate Social Networking web application, closely aligned with main Web 2.0 principles. This application allows our clients to maintain affinity groups subnetworks, provided and hosted as a service by SelectMinds, and linked to the clients’ main company web sites. Created, integrated, tested and rolled out a number of components and subsystems, on top of the SelectMind framework. Some of the Java components I have developed and currently am working on are:URI Processing/Dispatching System: designed, implemented and tested this subsystem, which processes a newly redesigned SelectMinds URI scheme, based on W3C Recommendations (specifically REST). designed and implemented a RequestEntryPoint servlet, a URI_Processor class, and a hierarchy of action controllers and handlers which this architecture relies on to completely process any HTTP request and return the response. reverse-engineered the existing legacy system’s UML model in order to document and re-use some of the existing code base. Used ArgoUML to generate class, object, collaboration and sequence diagrams, as well as use cases for assuring full functional coverage.

Participated in development, implementation, testing and rollout of the Markit Trade Processing system (MTP). Created multiple components and subsystems, on top of the ServiceMix/ESB/JBI/Spring and iBatis frameworks. Some of the Java components I developed were:Submit-fpml-service: receives SOAP messages (trades), performs authentication, dispatches requests for further processing(synchronous and asynchronous), creates appropriate response and sends it back to the http endpoint to be sent back to the clientValidate-mtp-service: performs XML validation against schema, stores any errors in a file and throws a validation exception, allowing the calling components to send “Message Rejected” response back to the clientMtp-query-trade: performs database queries to get the status of the required trade/message and prepare response model to be sent back to the clientMtpModelEnricher: applies business rules to fulfill internal model for storing to database(many more)Wrote files required to generate and transform FpML-based trade messages for confirmation by DTCC (xml and xsl) Wrote SQL queries and mappings to fetch and map data from the underlying Sybase database, required by the above modules (SQL and iBatis)Attended and completed ISDA FpML Training Worked on specification for integrating MTP platform with Swapswire.

Participated in an extreme architecture makeover/refactoring project of an existing tightly-coupled EJB/J2EE application. Modularized the codebase and adopted a layered loosely-coupled architecture, suitable for Spring IOC container (Struts was considered, but Spring was selected due to IOC/Dependency Injection, Proper Exception handling, and Aspect Oriented Programming). Simplified unit-testing external web services code by creating an external provider layer with well-defined Façade pattern interfaces and EasyMock mock objects. Replaced EJB entity bean persistence with data access layer using Hibernate/Spring integration, to improve performance and scalability. Decoupled business logic from the EJBs, allowing for out-of-container testing of every Java class. Participated in the analysis and design of intercompany solutions for the ordering and provisioning of global Telecom services. This included the high-level and low-level design of an Enterprise Application Integration (EAI) solution using BEA’s WebLogic Platform and Integration products. The implemented solution was based upon JMS messaging and included the definition of message naming and routing standards between North American and European EAI servers, the definition of XML based message format standards, and the use of XSL templates. The project involved working with the numerous BT affiliated companies in both North America and the European Union to obtain a solution design. Participated in the analysis and design of an intercompany B2B solution between BT and AT&T for the exchange of global provisioning orders.
