EXPERIENCE:

Sole Developer

Confidential, Houston, TX

Responsibilities:

• A Sample Tracker to keep track of the lab samples’ ownership and location.
• A Time Tracker to keep track of people’s time spent on projects.
• A Project Manager to break the projects down into smaller tasks and record the interaction of people versus projects and timelines.
• A Lab Test Manager to Extract, Transform, Upload and Download the Lab Tests’ data for supporting downstream data analytics.
• An Issue Manager to manage, log, and visualize the issues/problems encountered in the operations and resolutions.
• It re-uses the same set of tools and technologies used in VGOFFICE but is approximately 3 times the size of VGOFFICE.
• Created two command line programs in both Go and Python to upload the lab test data into the VGLABS database. Go program is more comprehensive in functionality whereas the Python program is simpler (simplicity won).
• Created three Visualization Applications using R and Shiny packages for a) creating and visualizing Ternary Diagrams, b) visualizations for a certain type of lab tests, and c) visualizations for the Fracture Analysis.
• Sample Selection and Uploader: This is an upstream application that sits before VGLABS. It allows the petro-physicists to select samples from a long ‘core’ of rocks for optimal analysis. It uses a complex set of rules defined in a rule-base. It is written in Python and leverages both NumPy and Pandas libraries.

Confidential

Principal Technical Consultant

Responsibilities:

• Responsible for the largest service contract awarded in Confidential history - Boeing Future Combat System program alone has generated over a 1 Million and Half Dollars worth of revenues for Confidential . I was the lead engineer responsible for servicing this account. FCS purchased Confidential ’s flagship product, UDDI Registry and committed to using it throughout the organization by paying for an enterprise license.
• I have advised, instructed, and hand held the Boeing’s Future Combat System Division’s SOSCOE Group’s personnel in:
• Learning Web Services - through reference materials and hands-on workshops.
• Implementing a comprehensive demo - to show-case the interoperability with the Department of Defense Information Systems Agency (DISA). The demonstration connects two large Systems as one System of Systems utilizing heterogeneous web services platforms and Confidential Registries linked via a bi-directional replication.
• This demo has assured the future funding for Boeing’s Future Combat System program participation.
• I used a variety of mostly open source software during the construction of this demo. A web-service broker wraps the SOSCOE Group’s CORBA/ICE based services and makes JINI calls to retrieve desired data. The web-service broker is hosted in a JBoss container. The client for this broker was a Struts/Tomcat Java application. The data-mapping is done using Apache Castor. The client allows users to select the desired service from Confidential Registry using service meta-data. Upon selection, the endpoint is retrieved and the service is invoked. The same setup works in reverse direction as well. Moreover, the SOAP communication is secured using Digital Signature and Encryption technologies using WSS4J, which, in turn, uses the Bouncy Castle Crypto Engine.
