Wrote FFT and developed heuristics to recognize notes, chords and hand techniques played on a guitar.

Specified, designed and implemented a search engine written in Java and Perl. The search engine is based on proprietary search algorithms written in perl. Web pages are pulled off the web, parsed, indexed and stored as data on the disk. The data is then stored in a BerkeleyDB and can be retrieved on a single Linux box in real time. The algorithm can be converted to a parallel Linux cluster. Built up Linux boxes, versions 5.2 and 7.2, installed perl/BerkeleyDB and other public domain supporting software. Specified, designed and coded algorithm for retrieving, storing and searching large portions of data in a timely and resource friendly manner. The product runs under apache does page crawling using Perl web packages then turns the page information into searchable data which is stored in a flat database. The database is placed under a web server and dynamic HTML is emitted for the users’ search.

Wrote an interactive Internet server: igs.panda.net Bay area and Albuq NM. Designed and developed an Internet server in C to allow over 4000 simultaneous players from around the world to play Go (over 730 million moves per year). Profiling done under DEC Ultrix with pixie performance tool as well as under sun using –prof. Developed support programs in HTML, Perl and Java. Developed a parser for go game files for people to search 100000+ files for matches in game play. Marketed and sold IGS in Taiwan, Korea and Japan. Installed Redhat Linux (5.1 5.2 7.2) and configured redundant drives for high availability fail over. Direct support of email for handling larger email load. Scripts to process large numbers of files for search and storage. Architecture and design of not only core product, but all supporting structures as well. Wrote a perl tool to search Go games for patterns. Wrote a perl tool for reporting users’ rating/ranking within the Go community.

Designed and coded a visualization tool for complex pedigrees in J2EE, using JDBC and Java Swing. Designed and started coding a LIMS system. The LIMS would either run as a stand-alone server or be placed under a web server. The LIMS was to be used for collection of patient data all the way to collection of genetic sequences and combined with pedigrees to determine patterns of genetic defects. Researched CFR 21 part 11 for electronic submission of documentation. Made recommendations for code and procedures for CFR 21 part 11 compliance.
