Professional Experience
, Raleigh, NC June 2010 - Present

Software Engineer



  • Developed a student management system in JDeveloper and Oracle Fusion Middleware (ADF/BC4J/JSPX/Weblogic) to create a rich web user experience.

  • Installed and configured Oracle 11g database (XE) and created simple web services that accessed the database through ADF application modules and view objects in JDeveloper.

  • Designed and implemented ADF Business Components using Entity Objects, View Objects and Application Modules. Worked with Data Controls and Task Flows.

  • Developed various programs using MyEclipse/Spring Framework, Subversion, and MySQL.

  • Created various dual boot machines including Ubuntu and Windows on separate partitions.

  • Used virtualization technologies including Oracle’s Virtualbox to install virtual machines on multiple operating systems such as the following:

    • Fedora and MAC OS X virtual machines on Windows 7

    • Various Window flavored VMs (Windows 8, 7, and XP) on Ubuntu

    • Mac OS X (Snow Leopard and Lion) on Ubuntu

  • Worked with various tools and technologies such as JDeveloper, Java, Eclipse, JavaScript, CSS, SQL, HTML, XML, Visual Studio, and Adobe Photoshop.

  • Used LAMP (Linux, Apache, MySQL, and PHP) for in-house software development.

  • Examples of software projects are as follows:


Patient Record RESTful WebService


  • Technologies used: MyEclipse, Java, JQuery, JSON, XML, Spring Framework, RESTful

  • Used JQuery for form submission, dialog-boxes, form field validation, form input field mask, dynamic behavior of page, error/exception handling, and form data serialization functions.

  • Created a RESTful web-service for patient records using an API (Greenway Medical) in order to fetch, parse and output data based on a given parameter (e.g. last date of visit or patient id etc.)

  • Created various patient portal web pages and forms utilizing Spring MVC Framework, Java objects, DAOs, service implementations of Java objects, request mapping/context path mapping, HTTP Request/HTTP Response mapping via controllers, and fetching data from JSON input.


XML Mapping and Parsing Techniques


  • Technologies used: Eclipse, Java, XML, DOM, SAX and 0/X Mapper

  • Developed program to check whether a folder contained any files and then parsed the input XML using a SAX parser.

  • Created Java objects and retrieved relevant data which was used to populate the back-end database.

  • Used the 0/X mapper under Spring Framework for XML Parsing.

  • Wrote various XML files using the DOMFactory Writer.


Simulation of Intra-Neuron Communication


  • Technologies used Eclipse, Java (and XML AP/s), JAXB 2.2.7, NeuGen, Dozer (XML Mapping Tool), JDK 7 (1.7 update 25), NeuGen Program and Algorithms

  • Developed software and algorithms for simulating brain functions, and more specifically intra neuron communication via dendrites and axons.

  • Implemented neuron topology generation algorithms and optimized these algorithms using various techniques such as Hillman's algorithm.

    • One example of such algorithm was an L-branching tree construction algorithm. The parameter L indicates the number of branches (i.e. child nodes) per a parent node.

    • Another example was writing code for computing 3-dimensional Euclidean distance between two XYZ coordinates.

  • Developed program for XML data conversion using enterprise mapping techniques between two different domains. For example the tasks was to take neuron simulations in a DTD compliant xml format and convert them into a Schema compliant xml format. Challenge was that input DTD and output Schema used different taxonomies.

  • Developed architecture for the following:

    • DOM Parser+ Custom Code (Read XML/DOM-> Custom Convert-> Write XML/DOM)

      • Writing Conversion logic became unmanageable due to generic nature of DOM elements and tree

    • Dozer Framework for mappings from XSD to DTD ->Write XML/DOM

      • Used for Enterprise Integration in Organization for mapping different models

      • Someone still has to write the domain model in Java

    • JAXB for generating Domain Models (both XSD and DTD) and using Dozer to define mappings-> JAXB Write

      • Generated domain models for both XSD and DTD using JAXB

    • Started using Dozer for mappings but ran into issues where deep mappings could not be defined in extremely complex cases

    • JAXB for generating Domain Models (both XSD and DTD) +Java Logic for Conversion-> JAXB Write

      • Generated domain models for both XSD and DTD using JAXB

      • Wrote custom logic to convert XSD domain model to the DTD domain model

    • Create Domain Models using JAXB xjc Compiler


Challenges in Intuitive User Interface Designing


  • Technologies used: MockFlow (app.mockflow.com)

  • Researched and developed an in-depth report regarding pros and cons of user interfaces of some of the leading OSs (Mac OS X, Windows 7, and Ubuntu).

  • Analyzed and dissected usability and user interfaces of technical discussion group oriented websites such as stackoverflow and stackexchange.

  • Designed user interface using mockups (MockFlow Wire framing) for a physical book release that included designing discussion group, help, homepage, contact page UIs.


Streamlined Shopping Experience Development


  • Technologies Used: JavaScript, CSS, SQL, HTML, and XML

  • Developed and implemented a website to demonstrate a streamlined online shopping experience that included utilizing screen space effectively and reduce scrolling.

  • Developed frontend using XML, CSS, JavaScript, and HTML in NetBeans.

  • Used XML to define the DTD and MS SQL database; database procedural calls were utilized for data access.

  • Used CSS to style the website and JavaScript in a reusable modular manner (globally).


College Walkthrough Website


  • Technologies used: JDeveloper, Java SE, Java 2D APIs, and HTML

  • Developed and demonstrated a portal to give students a ‘first person view’ of the college campus.

  • Developed the frontend using HTML, CSS, and Dreamweaver.

  • Developed animation using Java 2D graphics APIs that included using a set of images and sequenced (animated) together with reference tags in HTML.


3D Shape Rotation


  • Technologies used: C++

  • Designed a software program in C++ to generate full 3D views with rotational capability of different objects such as pyramids and cubes.



, Mumbai, India June 2009 – March 2010

Software Engineer


  • Used SAP Basis Module for client transaction management using T-codes and used UNIX platform for error handling.
