Lead developer of iportal 2.0, an integrated data and workflow manager; complete tracking of all source code, data (the exact version known), all parameters. Workflows and results and be reproduced with high accuracy as the global state of the computer systems carrying out the work is specified. 39 scientific workflows implemented as of January 2019. Can be deployed on clouds and containers. |

| 2007-2009 |
Designed, purchased and built the Apollo computer cluster with 200 quad-core Xeon 64-bit processers in 100 Dell computer chassis. A 22 TB polyserve SAN storage solution was exported to the rest of the cluster using NFS by three load-balanced file servers. Maintained and supported users until the end of my postdoc and then served as an external advisor until Apollos decommission in 2013. |
| 2001- |
Contributed to Rosetta and auxiliary software to improve molecular modeling and molecular design. Rosetta is open source for academics. |
| 2001-2006 |
Built the YRC computer cluster with 80 single-core Pentium PIII CPUs in 40 supermicro computer chassis with a 2.2 TB storage served to the rest of the cluster using NFS by 4-socket file server. Installed all software and maintained the cluster for the rest of my PhD. Supported users of the cluster. |
| 2000- |
Lead developer and architect of the DDB open-source scientific computing and data analysis software suite. Software available through sourceforge.net since 2004 (http://sourceforge.net/projects/twoddb) under the GPL license |
| 1985- |
Received my first computer as an 8-year old, programming working with hardware and system administration throughout my childhood and teenage years. Started working professionally as a system administrator and system designer at 15 eventually starting a small consultant company. |
