Python was used to develop Linux script on Virtual Machine Ubuntu which did:
1) CGI script runs on Apache server,
2) pulls data from Postgres SQL,
3) present data in web browser as HTML
4) present data in XML file in RSS Feed
5) updated results are send automatically to Managers Outlook Mail Box.
6) Pulled financial data from web by PERL/PYTHON script using XML TREE, DOM
7) Used Django framework
8) Used RESTful technology for API
9) used OCR tools with 508 compliance for development and testing
10) SANS cyber security classes
NOAA Senior Production Analyst (contractor) 05/2011-10/2012
Camp Springs MD
I run Weather Forecasting Models on IBM supercomputer.
1) Deployed new models for automatic run on Unix machine by LoadLeveler
2) Monitored them by SMS Linux box.
3) Tested existed models for additional changes and enhancements, for example (SREF,WRF,GFS,WAVEWATCH).
4) I responded to night calls for troubleshooting of model crashes and delays. This include monitor of data ingest from satellites or data input from other models. I have knowledge of GRIB,GRIB2. I supported AWIPS.
5) I used PERL script 24x7 automatically collected errors from all sources and make log file.
C/FORTRAN were used for support and development of weather forecasting models.
C/C++,FORTRAN/PERL/Python/shell script. Linux, Unix AIX, HPC, Open MP/MPI
6) I used GPFS and Open MP which is DISTRIBUTED SYSTEM
7) used OCR tools with 508 compliance for development and testing
SCIENTIFIC PROGRAMMER (contractor) 06/2010-12/2010
Fugro Earth Data Frederick MD
Production of surface maps from 2 air born Synthetic Aperture Radars (Interefometry) data in X and P bands. SAR / IFSAR data processing SGI 3900, Altix 4700, Irix, Linux, FORTRAN / C, parallel programming Open MP/MPI, Jurassic Prok (JP), Porting of JP from SGI Irix to Altix Linux box. Performance improvements by re- engineering of source code with possibility to reprocess data faster. Improvements in performance of making shape files on C/C++, breaking JP in part to dump results on disk on 1 run and pickup data at 2 run for smaller needed map area, what allows redo it much faster. PERL code run data comparison produced by different methods.
