  • Leverage diverse experience in all phases of the software development life-cycle.
  • AEHF distributes operational software at the Secret or Secret/RD level. RDScan is a tool that searches all released software for text sequences which are restricted by the department of energy. All text and binary file types must be scanned prior to a Mission/COTS release.
  • Restricted text sequences are submitted for analysis to determine if data must be removed before downgrade to secret. Reliability and performance of RDScan is critical, since it is in the last stage of the delivery pipeline.
  • Architected and implemented the following solutions for RD Release Downgrade Scans.
  • Completed design and full implementation of Perl text scanner to scan all AEHF releases for downgrade.
  • Created dynamic Perl regular expression generator for ASCII and Unicode sequences in multi-gigabyte release packages.
  • Created Master/Worker dispatcher to make any arbitrary number of scans run in parallel.
  • Created extension to recursively de-compress arbitrarily nested Tar, Zip, Gzip, and Jar files.
  • The extension handled any combination of nesting of any compression type to any nesting level (up to process memory limits).
  • Create ClearCase and ClearQuest (CQ) Discrepancy Report business logic (DRs) to track enhancements and defects across a range of development platforms to guide the change-process.
  • Combine custom and COTS products to provide high performance mission development environments.
  • Created comprehensive test-automation-tool to ensure enhancement reliability through automated regression testing.
  • Designed and coded Oracle Java JDBC and stored procedure based tool to independently verify archive integrity.
  • Created 8K SLOC Perl regex transform system to convert legacy-DB XML/Jason records for successful import into new DB Schema.
  • Achieved a 10X runtime performance gain on Perl DB field extraction utility script via multi-threading.
  • Architected and implemented software to move CQ business logic from Oracle SQL tables to file-system script-libraries.
  • Conceptualized and implemented Patch Methodology to place all ClearQuest logic under CM control.
  • Achieved ClearCase Integration in Perl, IIS, and ASP for itemized file associations of over 105 files for a single CQ SQL Record.
  • Achieved 15:1 SQL DB size reduction through scheduled attachment archiving of selected records.
