Role: Technical Consultant

• Description: This store is a rapid expanding food chain restaurant with about 35 branches and planning to expand to 100 by 2014. This application is an ERP developed for them to control the headquarters and branches. The application controls sales, inventory, order, payroll and finance of the whole restaurant chain. Since POS in branches used atom processors and the network coverage were poor at some locations with intermittent breaks optimization of the application along with minimal network usage were critical. Given the poor network coverage, real time data synchronization with centralized server at headquarters was challenging. Since open sources were used, client could cut down the cost of development effectively.
• Responsibilities/Achievements: Designed and involved in the development of Data Synchronization module which is a core part of product. Swing was used as UI and core java was used as components. Real time data synchronization was managed even during intermittent network connectivity. Multiple threads were used to reduce data transmission latency. Since server is on PHP and client is on Java, client side app used RESTful protocol JSON to exchange data. I developed Java components to distribute data to multiple MYSql databases at server side. These data were sent back to client as AES encrypted files. Application is secured by user login passwords, which were MD5 encrypted and stored in local SQLite database.
• To support different makes of thermal printers, a customized component was developed to replace the device drivers. UI developed in Swing allowed to store Unicode instructions in SQLite local database. To configure a device, its Unicode instruction needs to be keyed into application. This gave the ability to connect almost any thermal printers to the device.

Environment: Java for data publishing components, Unix is the OS at server side, PHP for server side development, MySQL as database. Client terminal used Ubuntu Linux based as OS, Java for client side development, SQLite as database. CVS was used as code versioning tool.

Role: Team Lead

• Description: This University has an online class room for desktops. They wanted to roll out this application to mobile device, so that students can attend the class while travelling. As a pilot project, it was rolled out on iPhones. Because of screen size differences and broader scope than desktop application, UI and flow of application was redesigned. Since the data required was not directly available from a web service, they had to be called sequentially and processed to get the required information.
• Responsibilities/Achievements: Since the project was outsourced to offshore, real time interaction between the client and development team was challenging and critical. For architecting and UI re-designing, client had rolled out a separate onshore team for the project. My role was to work with them to discuss the flow and identify any gaps in the UI and conveying the ideas back to the offshore development team. Since the development was on Agile model, Scrum meetings were to be attended and keep management updated. Had to monitor development progress and identify risks and mitigate it. A close interaction between onshore and offshore was required. Once the flow and design were finalized, went back to offshore, to work along with development team. Application bandwidth usage was tested and controlled using WireShark, since network may not be strong or stable.

Environment: Windows was development environment with iOS simulator, MagicDraw for developing UML diagrams, WireShark for testing network bandwidth usage, iOS and ObjectiveC on iPhone devices, SQLite as its database and iPhone devices. CVS was used as code versioning tool.

Role: Team Lead

• Description: There were multiple applications in multiple technologies. The team size was 1000 developers spanning on two geographical locations. My team owned a set of applications developed in Java. These applications were middleware utilities and web services used by different applications. Among them was a data access layer web service, which retrieved data from Oracle database. According to the parameters passed, specific details were retrieved and passed back to the caller application.
• Responsibilities/Achievements: When new application requirement is received, need to analyze it and design the flow for new functionality. Provide estimation and ETC for the project. Prepare test cases and involve in code development with the team. Also had to do code and testing review. Raise the Change Control and assist in implementing the code. Provide weekly updates to onshore and offshore management.

Environment: Unix and Windows were the OS, WebLogic was the Application Server, Oracle was the database, Spring and Hibernate was the framework, ClearQuest was the bug tracking tool and ClearCase was the code repository.

• Description: Since it was a new team deployed in Accenture for Visa, it was hard for the management to streamline and monitor the projects. So it was decided to roll-out IBM RequisitePro, ClearQuest and ClearCase together for gathering requirements and managing the projects till Testing.

Responsibilities/Achievements: Since the team was new to this environment, proactively learned the tools to be used in the project. Documented its functionality and usage. Conducted telephonic sessions for the whole team on both the locations. Thus was able to assist management in rolling out the tools smoothly.

Role: Team Lead

• Description: Due to the size of the project, applications were divided in two geographical locations with more than 400 developers. There were multiple middleware applications which were owned by my team. One of the applications was an interface provided by Stored Procedure SP in Oracle 9i. It used Fa ade design pattern. This SP was used by many applications. According to the parameter passed, request will call other internal SPs to process and retrieve collection of data from multiple tables. These collections of SPs were consisting of more than 2000 lines of code.
• Responsibilities/Achievements: When the requirement comes, needs to analyze the requests and design the flow of the application. Calculate and provide ETC for the task according to the resource availability. Later getting involved with the team in development, reviewing and testing the code. Raise Change control request and get it approved. Assist implementation along with the team.
• Description: Another application was for transferring files created by other applications, securely to different server locations. This application maintained meta-data that can be configured. Application was executed as a daemon thread in the server. In case of its crash, a configured Tivoli job will invoke it at a regular interval. In meta data user could define the start time of file polling for each type of files, its source location, destination location, retry count in the event of a failure, end time of the polling, protocol to be used for transferring the file and email group on which failure notification needs to be notified.
• Responsibilities/Achievements: In the existing application, file transfer failed at-least once in a day, thus bringing monthly trouble ticket count to 25. Since it could transfer only single file at a time, complete file transfer took hours. The flow of application was redesigned and developed the code. Thread concept were introduced to facilitate simultaneous file transfer. This resulted in parallel file transfers thus bringing down file transfer time considerably. Analyzed the nature of file transfer error occurred in existing application. Proposed an alternate flow for the exception, which enabled the application to be resilient. This brought down the trouble ticket count to zero.

Environment: Application functioned on Unix environment, Core Java was used to develop application, Tivoli was scheduled for invoking application, Unix Shell Script was developed to start the application, Oracle was used as meta-database, SFTP connections were established between source and destination server locations. ClearCase was used as code repository tool and ClearQuest was used as defect tracking tool. PVCS was used as code versioning tool and Jira as defect tracking tool.

• Description: There were few middleware applications owned by my team. Its enhancement and maintenance was the primary responsibility. Data access synchronous web service, iFast was the most important among them. Its functionality was to act as middleware between customer service applications and backend mainframe. The purpose of application was to implement a secured layer between application and database. 68 applications were using iFast interface to access mainframe data. iFast catered 2000 transactions per minute. It was deployed on two geological locations East zone West zone on BEA WebLogic cluster consisting of three servers on each location with a load balancer.
• Responsibilities/Achievements: Requirements coming from applications need to be analyzed for the feasibility. If feasible, need to estimate the task involved, identify and mitigate any risks, design the flow of application and get the development done. The code and test cases needs to be reviewed before the application went for QA. Once QA has certified it, need to raise Change Control for implementation. Once it is approved, need to assist production control team to implement it. Change control happened once in a month and system needs to be up by 24/7 on all 365 days. So implementing the changes without interruption was critical. I was involved in stage-by-stage implementation. Implementation involved re-routing of traffic to West zone before implementing it on East zone, and then re-routing traffic to East zone before implementing it on West zone. Since the traffic was heavy, least traffic time was selected for implementation. Application could record an uptime of 99.9 .

Environment: Unix was the application environment, Java, BEA WebLogic Servers, Spring, Hibernate, Load Balancers, Routers, Oracle database, MQSeries Server. ClearCase was used as code repository tool and ClearQuest was used as defect tracking tool.
