John Quigley’s Experience

• Lead Software Engineer

  Cleversafe

  (Privately Held; Computer Software industry)

  October 2005 — Present (3 years 10 months)

  * Dispersed storage core: Worked on full life-cycle design and implementation of Cleversafe's Java-based core dispersed storage software. The system implements a distributed system for the storage of data that had been operated on by a channel coding algorithm. The algorithm decomposes input into data and code symbols, allowing the original source data to be reconstructed by various recombinations of symbols.
  
  * iSCSI target: Company's go-to-market offering, providing first streams of revenue. Personally designed and implemented the commercial iSCSI target allowing a user to interact with dispersed storage medium from the network as if it were a standard SCSI block device. Fully RFC3720-compliant, and fully native to Java.
  
  * SCSI target: Team lead on design and implementation of the commercial SCSI block device target that presented a dispersed storage volume as a standard logical unit. SAM-2, SBC-3 and SPC-3 compliant, and fully native to Java.
  
  * dsgfs: Designed and implemented a POSIX-compliant file system for Cleversafe's unveiling demo at LinuxWorld. Allows a user to interact with a Cleversafe dispersed storage grid as a standard UNIX file system.

• Computer Science Researcher

  IIT Code Group

  (Computer Software industry)

  2006 — 2008 (2 years)

  * White Programming Language: Conceived of and led design and development on an ambient-oriented distributed programming language for mobile networks based on the actor model. System inspiration taken from Erlang, Self, LISP, Io and Smalltalk. Prototype-based and deeply reflective object model.

• Computer Science Researcher

  IIT Information Retrieval Laboratory

  (Research industry)

  2004 — 2006 (2 years)

  * Diesel Search Engine (Northrop Grumman contractor): Lead engineer performing development and statistical analysis of recently declassified, distributed and highly-concurrent search engine for multi-tebibyte datasets. Developed test and result metrics analysis tool chain in Python and R.
  
  * SQLGenerator (BIT Systems, Inc. contractor): Development of the custom XML-QL grammar, parser and query compiler, allowing for XML documents to be indexed into a RDBMS and queried via XML-QL and XPath.
  
  * Mediator Search Engine (US Holocaust Memorial Museum contractor): Development and integration work with the Java- and Python-based Mediator search engine, a data mediator that integrates searching structured, unstructured and semi-structured data sets. Development focus on the natural language query parser and result filtering chains.

• Software Developer
