Java Architect / Developer/ Lead

Responsibilities:

• The current assignment I am working on is in Tools Department for Web Performance. The tools being developed is to provide what if analysis for various optimization techniques. The four optimizations like Cash/Prefetch/Inline and compression is included in the current version of the tool. The tool is flexible enough to add further optimization techniques with few enhancements.
• Technology used is MVC architecture with .net 3.5 and SQL server database and C# using VS2010. Tool used open source to import data into SQL server and hence was necessary to use the architecture as above. Various screens have been developed using HTML/ Master Page/ Web Forms and Java script. Stored procedures have widely been used as well. The code separation techniques have been used to separate various layers like database, models and Controller. Also, Auto list handlers are written using JavaScript making AJAX calls.
• Web Application Architecture using MongoDB, Express, Node.js, and Angular.js
• The project has been started with requirements document. Created various artifacts including detailed design document, Data Model and Screen Design. The project is almost at the end of coding.
• The tool heavily uses TCP/IP, HTTP protocols. The timings for the packets (Frames) are available in database via import of the capture and tool uses TCP connection for further analysis.
• TCP/IP Sockets based protocols and network programming.
• Node.js REST API development using Express, to be consumed by Angular.js services.
• Also doing web analytics using Hadoop Map/reduce for the data stored in HDFS. The system is based on Linux and Hadoop is running on top of Linux. Wrote various customer transaction queries for loan Management includes loan making and loan servicing.

Java Architect/Lead/Developer

Responsibilities:

• I have extensively worked on DST’s AWD10 product.
• Create a new user, specifying general attributes such as name, user ID, security level and work group. This can be done using another user or a model user as a template, such that privileges, experience levels and resources are inherited from the model.
• Manage what they can work on, by assigning one or more roles, assigning individual privileges such as specific business areas or work types that are beyond the capabilities of the assigned roles, and assigning experience level.
• Manage what they can see in AWD, by assigning security group, and additional individual resource access control grouped by product/capability.
• Specify resource-specific attributes, which are the additional parameters required for the different capabilities to which they have access, e.g., the signature that will be used for correspondence generation if they have access to the correspondence capabilities.
• Inbound scanned documents, faxes, emails, tweets and other sources
• Forms builder for data capture user interface
• Process design (apparently with BPMN), including service calls and subprocesses
• Created the Front end page - using JQuery, JavaScript. This is called mash up screen. It gives information about participant info/Plan Info/Sponsor Info from ALIS record keeping system.
• Used SDLC process from development to deployment to higher environments. Worked extensively on bug fixes on the server side and made cosmetic changes on the UI side.
• Part of performance tuning team and implemented caching mechanism and other changes.
• Recreated the system architecture diagram and created numerous new class and sequence diagrams.
• Modified wsdl model to create token and GUID services. These services are used to retrieve information from ALIS record keeping system. Seibel CRM - model changes are made for opportunities and various other entities
• Used Java Map/reduce architecture to process Plan/Participant information / Wrote Pig queries.
• Wrote Bar Graph using java collection framework. The data is presented to the user using oracle database 11g PL/SQL oracle stored procedures. These include use cases to UML and code creation with Object Modeling. The code used design patterns like Singleton/ Decorator.
• Completed two projects with map/reduce technology with hdfs file system. The first project uses naïve bayes algorithm to produce results from hdfs file system with large data. Also used pig language.
• The second project produces web analytics using the log file which has large data. The file is loaded in hdfs and then map reduce program applies on customer and transaction records to produce reports filtering customer with certain transaction amounts.
