 Learned Hadoop/Hbase basics. Took over ownership of managing two remote production Hadoop clusters (CDH3), and multiple staging/test clusters using Cloudera Manager. Setup a new cluster to use CDH4, added HA for Namenode and JobTracker. Created a new production hadoop cluster using CDH5. Added Phoenix, Flume and Hue. Wrote multiple Perl scripts to handle logging, archiving and ingestion of customer data. Updated Perl and Bash scripts to work after moving an entire setup to a new remote data center.  Modified multiple Perl scripts: cleaned up, commented & added new code to find the first an available remote system from a list. Modified to use rsync via ssh for an entire directory at once instead of one file at a time. Learned a little ElasticSearch. Setup a db, wrote a Java class to add data and search by all or select indices. Delivered the Java class to production, replacing standard db for two select tables. Create a mysql db with two tables, one having a compound key. Wrote & debugged a Java lib using hibernate to interface with the tables. Wrote and debugged a Java program to interface with multiple db’s using Jedis (redis) and Spring-boot. Added junit tests, embedded redis and Swagger to test the code and REST interfaces

Language: Java, PHP, Struts 2, Hibernate, JSPs & Servlets: Mac OSX, EclipseDesigned a multiple many-to-many database. Added pivot tables to access the data, add indexes to optimize. Wrote PHP code to access the data and display various combinations of results in tables per user request. Picking up/using Struts 2, Hibernate, JSPs & Servlets to use in the current customer project.

Worked on a new app for Xfinity TV, coming to the public soon. Using Java added new features, refactored existing code to simply, fixed bugs, improved UI experience.

Worked for cloud team in Java adding methods to acces a basic database using jdbc. Part of the embedded book-read team using C/C++, enhanced & fix the reader. Helped the drm team creating encryption/decryption code. Helped modify the reader code to run as an iPad app. Added module/level logging in Objective-C

Designed and developed multiple department web pages using Microsoft's Sharepoint server.Created a Perl script to simplify the use of the UNIX NetEm tc command.Evaluated AMPQ providers with respect to our requirements for that product. Using C++ on RedHat Linux: Designed, developed, debugged and integrated interface library. Created processes to handle all communication between an input process and multiple output processes communicating through the OpenAMQ messaging bus. All of the work was completed within tight time constraints for the annual products show.

Created Proof of Concept for an external system specification for a browser based Java program. Developed and delivered on schedule critical website enhancements using Spring MVC, Java & jsps using the system specifications.Researched, designed, implemented, and integrated a repository cache library two weeks ahead of schedule.Wrote a standalone Java program to create, distribute, and validate X.509 certificates enabling a NonStop system to run on blades architecture. (Technologies used: SSH and SOAP) Delivered on schedule and is currently being used internationally with no outages or customer complaints.

Improved the system security of a web based Java application by adding the infrastructure to use JavaHelp for the help system.Wrote sections of an Architecture Design Document to automate QA regression testing of a 500k loc server on a NonStop system.Wrote the detail design document, coded, peer reviewed, debugged and tested a Java test client to automate regression testing of a large server to cut down the test time by near fifty percent. Enhanced the server code to enable communication with the test client.Prototyped a new command line debugger (learning Lexx & Yacc). Initiated investigation of the necessity for a third debugger, determined that it was not necessary resulting in the cancellation of the product saving the company at least a person-year of work (code, test).Interfaced with users to clarify requirements for viewing of a packed system message buffer in a debug watch window. Wrote, debugged, integrated and delivered the new feature on schedule.Redesigned a debug server to handle 64-bit data addresses, 32-bit code addresses while maintaining the capability to handle various older system addresses. With one month until the final code freeze it was decided that the code needed to be internationalized. Interfaced with a Japanese customer representative to internationalize a debugger to handle Unicode for source window and watch item values. Designed and developed the code, wrote the QA test requirements document and QA tested the changes, The system was delivered on time.

For Applied Signal Technology, Inc: On an embedded Windows system: enhanced an existing process to spawn another process and receive data through BSD sockets, queue the data, and create another thread to send the data to a different process using MFC sockets.Created a background display on the main window (in C++) of the current system including the state of each machine and each network element.Took a baseline Sun UNIX system and redesigned it, removed existing windows and added new windows. Built and debugged a new process to run on SCO Linux adding new capability to ftp data files to NT system or copy to NT formatted Jaz disk

Came on board, assumed the responsibility to complete unassigned work: Debugged an existing multi-threaded MFC process, adding the capability to read the registry for initial values. Created an MFC process to start at system boot time, install (or delete) another process in system services and add initialization variables to the registry.Took over the responsibility to complete a ground station display using Visual Basic for the UI and Visual C++ for the interface methods. Converted inter-process communication from SNMP to Talarian’s SmartSockets.Using RTWorks software: wrote processes to archive and retrieve data displaying messages interlaced with log data and sorted by time. Implemented a process to extract selected data from multiple database tables. Played key role for test and integration team, setup operational environment and ensured that software ran properly on target platform to meet a major system milestone.

Designed database tables, developed stored procedures to create and access tables, and wrote C++ source code to interface with a Sybase database which enabled the I&T team to test an embedded system.Redesigned a process condensing multiple windows into a compact set of user friendly windows. Converted a foreground process to run as a UNIX daemon process. Wrote programs to communicate via serial ports to two high speed tape drives to synchronize recording and playback of tapes. Designed, wrote, debugged, tested, and integrated background process to scan input directories for new files, parse the files, and create names determined by file content. Wrote a shell script to run as cron job to take snapshots of an archive directory, compress and tar the files to tape and remove backed-up files from the system.
