Designed and implemented the nderground social network (www.nderground.net). The nderground social network offers it's users privacy and security. nderground is a large scale web application designed for scalability, security and privacy. The application is hosted on Amazon Web Services. Hosting is provided by Elastic Beanstalk/Tomcat. Database support is provided by Amazon RDS/Postgres and DynamoDB. Storage is supported on Amazon S3. Email support is provided by Amazon SES and Mailgun. The application is designed to be secure and uses cryptographically complex salted passwords and other features.In order to leverage the huge Java virtual machine ecosystem, the application is implemented using Grails, in both Java and Groovy. The user interface makes use of Bootstrap, jQuery and the Redactor editor. All content is dynamically generated.

* Network Mapping and Network Analysis Wrote Java software to provide on-site analysis of sponsor computer networks. Traveled to a variety of sponsor sites to perform network analysis.* Embedded Software As a member of a small software group I developed and modified multi-threaded software to support an airborne spectrometer. This software was written in C++, making heavy use of the Qt class library. * Text data-mining and document triage As part of a two person team I built a document processing pipeline for very large document sets that was customized for a variety of document types. This pipeline processed Microsoft documents, PDF files and images. The document search and triage made use of the Solr faceted search system. The pipeline and associated software was implemented in Java. * Distributed Semantic Graph System Database System o As the senior engineer in a two to three person team, I designed and implemented a semantic graph query language. The query language ran on a distributed system consisting of processing blades and database systems. o As a member of a research group, I designed and implemented an innovative graph graph query language and its runtime support for a parallel database system. This query language is described in the technical report A Semantic Graph Query Language by Ian Kaplan, Lawrence Livermore National Laboratory, October 17, 2006 UCRL-TR-255447 (PDF format). o As a member of the semantic graph database research group I found optimal methods for translating pattern queries into relational SQL. This is described in the technical report Implementing Graph Pattern Queries on a Relational Database by Ian L. Kaplan, Ghaleb M. Abdulla, S Terry Brugger, Scott R. Kohn, Lawrence Livermore National Laboratory, January 8, 2008, LLNL-TR-400310 (PDF format)

As part of an approved outside consulting project, I developed an intraday trading system for a start-up hedge fund. This system was developed in Java and implemented using Web Services (deployed on Tomcat). The software consisted of 4K lines of Java code. The system used the Interactive Brokers platform for trade execution.

* As part of a small team, I worked on the design and implementation of a computer driven equity trading system capable of supporting near real time orders submitted by multiple trading products. I wrote a large portion of the design documentation for this system, which evolved through three major design iterations. * I developed wavelet filter based predictors for financial modeling and trading and applied a variety of statistical tests to verify the effectiveness of the wavelet predictors. * I maintained and extended Prediction Company's time series software and financial modeling infrastructure. I documented this system so it could be used by Prediction Company quantitative analysts.

* March 1998 to July 2000, Project Lead, HDL Simulation Compilers Project lead of a group of three engineers responsible for the development and enhancement of Quickturn's SimServer Verilog and VHDL native compilers. Worked extensively with customers and marketing porting Verilog applications and benchmarks. Developed project schedules. Added code generation support for VHDL and enhanced Verilog code generation and runtime support. * February 1996 to March 1998, Senior Software Engineer Developed a behavioral Verilog HDL compiler for hardware/software co-simulation on a reconfigurable computer system. I have been a key member of a small team that developed this compiler, which is now in alpha test. I wrote over thirty-five thousand lines of C and C++ code for the front, middle, back end of this compiler. I have also developed a large part of the compiler runtime.
