This involves Linux VMs running in a VMware environment:Added many new features to the configuration database code. This is a C++ abstraction layer over a Postgres database; the abstraction layer also adds automatic node-to-node data replication.Added many new features to the control plane code. This is a C++ implementation of a Thrift interface used by the REST layer and the CLI commands. The control plane is a multi-threaded process, with many event-driven threads. It also makes many inter-process and inter-node calls.Enhanced the lower-layer interface for the REST server that provides the functionality for a REST-to-Thrift interface.Developed API software for HPE’s StoreVirtual product line:Developed code to implement a REST/JSON server, to support a new web-based GUI management interface. This involved code to integrate the REST server to the lower-level processes, and implement the business logic to configure and control the system.Conducted and interpreted security vulnerability scans. Implemented fixes and/or directed other teams to fix any issues found.As a member of the software security team, investigated and fixed several security escalations, found both internally and externally. Supervised a security penetration test of the product.Ported the code base from an x86 processor so that it would compile/run on an ARM processor; the end result was a single code base that could be native compiled for x86, or cross-compiled for ARM.Worked in an Agile/Scrum development environment; occasionally served as assistant Scrum Master.Developed and maintained software for HP’s enterprise-class tape libraries:Maintained and supported the Interface Manager product; highly object-oriented C++ on an embedded Linux environment.Extended the Linux SCSI Tape Device Driver to support a new Fibre Channel path failover protocol for HP’s LTO-6 tape drive.

Designed, developed, and tested code to add a multi-partition feature to Qualstar's flagship XLS tape library. This feature also allowed multiple hosts to connect on multiple SCSI and Fibre cards. This was developed in C++, in a Linux environment.

Developed many enhancements and bug fixes for all of Exabyte’s tape libraries.Designed and implemented code to handle commands from multiple SCSI and Fibre hosts. This allowed for multiple partitions within a single large tape library.Designed and implemented new, low-cost embedded Ethernet module. Integrated a commercial TCP/IP stack into the custom ARM-based code, and developed the code to interface to the PHY chip. This module provided FTP, E-mail, SNMP, and web… Show more Developed many enhancements and bug fixes for all of Exabyte’s tape libraries.Designed and implemented code to handle commands from multiple SCSI and Fibre hosts.
