Stark Services has provided a web based tool for customers to access their data. It was a windows, lotus notes, IIS environment. The performance of the site was too slow and Stark Services did not own the servers or the software that was used for the site.

Developed an in house solution that would address the performance problems. Proposed a Linux, MySQL, Perl, Apache solution based on CGI::Application, and HTML::Template. This solution was approved and the system was built and deployed as www.circdirect.com. This system contains over 40 publishers’ magazines covering over 1.5M subscribers. The tool allowed for fast reporting of subscriber demographics for each publication.

Managed this product to production as it went through unit, incremental, integration, functional, system, acceptance, load, performance testing cycles. The code was all managed using CVS and all bugs/enhancements where tracked through Bugzilla.

Continue to provide bug and enhancement support for CircDirect based on new requirements.

Served as Technical Professional working with a team to manage, design, write and support a company-wide system (System Examiner Tool Set or SXTS) and helped transition from RCS to Clearcase.

SXTS is a set of programs tools and databases that are used to evaluate all servers at Boeing and provide reports on configuration and discrepancies of systems configuration. The distributed Boeing environment makes it very difficult to get a central picture of all Boeing servers. SXTS addressed this problem by being an integrated part of all Boeing OS block points. The SXTS agent is included as a part of each (Sun, Sequent, AIX, HP, Linux, Windows) basic OS install. It was a small C program that was based on Sun’s RPC. The agent allows a trusted remote user to do three things: execute a file on the server, transfer a file to the server, or copy a file from the server. With these three abilities available in a common way across all platforms, we then developed a system for automatically going out and identifying new servers on the network by giving them an ID that can be tracked over time and collecting basic data about the servers. Through this tool anything that was required could be collected and loaded into a central database, then reports were generated through a web interface for review. This system would, on a nightly basis, talk to over 35,000 names on the Boeing network and collect data on over 10,000 servers.

The SXTS environment consisted of the C agent that is on every server, an oracle database running on a Sun Solaris server, and a number of different web interfaces, some using IIS, ASP, Windows and others using Apache, Perl, HP-UX. It also included a number of data collection scripts all written in Perl.

The database, web, and data collection portions of this system were on a monthly release cycle.

Performed integration, performance, system, regression, unit, and acceptance testing. Then released software to production. Software was tracked using Clearcase and a Boeing developed bug/request system.

The C agent was also used on AIX systems for doing remote installs and upgrades of most AIX products.

Responsible for all corporate technical issues and infrastructure. This included supporting office productivity (software, computers, phones, electrical, network, facilities) and providing all support for production systems (online credit card transaction processing, web hosting, credit card help information, supporting other merchants using our credit card transaction software system).

For production systems, responsible for network, computers, facilities, electrical, A/C, architecture, security and software design and development.

Managed development team for existing products and next generation systems.

Managed sysadmin staff.

Provided status reports and direction for technical issues to management team.

ICN consisted of two facilities: corporate office, server room.

The corporate office had 2 T1 running into it: one for data, the other for voice. The data T1 was connected to a cisco router which was then connected to cisco switches. We had 2 office servers that were Intel based running Sun Solaris. Servers ran SAMBA, DNS, sendmail, Web, lpd and DHCP services for office network. All e-mail was accessed using POP/IMAP. Network printers were also queued using servers. Desktop systems were either windows or mac. Voice system was all provided using a Toshiba Switch and Toshiba telephones.

The server room was housed at Exodus. Two full racks were purchased to hold all the servers, modems, switches, backup tape drives, and dial-up servers. All the servers ran Linux or Sun Solaris. All customer services were provided through in house developed web interfaces written in perl for apache. We used MySQL for all database requirements. Sun machine running Firewall1 provided security for the production servers. A modem pool of 20 modems was used for making all credit card transactions. Modems were hooked up to a Sun with a scsi serial port extension. All servers had serial access from Dial-Up so if needed could be shut down, re-configured and upgraded remotely.

The software used for web interfaces was managed using CVS, and RT. The developers shared both test and developer roles; what ever one developer developed another developer would test. Tests would consist of unit, integration, performance, acceptance and others depending on what was being worked on.

Reviewed internal development processes. Made recommendations on how to improve processes. All servers were Sun machines running Solaris. Desktops were all windows based. Depended heavily on AutoSys to manage and schedule development builds and testing cycles.

Developed a tool for automating the creation of JIL code for AutoSys that started, stopped, and reported on development builds, and tests.

Examined customer site Sun servers that used Belvedere’s product to determine if the configured servers had any hardware or software compatibility issues for Belvedere’s product.

Contracted to Boeing as System Performance Test Manager in the Scalability Test Lab (STL) for the DCAC/MRM system.

Responsible for design, development and execution of test plans to identify performance issues on any servers or infrastructure. DCAC/MRM uses a large three-tier system. Sequent servers were used as clustered oracle database servers. The cluster included EMC drives connected to the Sequent using Fiber Channel. The Scalability Test Lab involved stress, performance, load, end-to-end, and system testing using LoadRunner, Xrunner and WinRunner from Mercury Interactive to aid in testing. Many other tools were also used for collecting performance metrics of network, cpu, memory, disk, bus etc.

Prepared tests to simulate various situations that could be expected in production to evaluate how the system as a whole would respond.

Made recommendations based on test results in the areas of infrastructure (network, hardware, cpu’s, disk layout, number of databases, number of servers etc).

Worked on company-wide system management and strategic architecture initiatives.

Primarily participated in Starbucks evaluation, and selection of a system integrator. MTI was selected to implement a company wide problem/request tracking system using the Remedy software.

Was also involved in evaluating, and selecting EMC storage systems as the primary data store for data warehouse.

Managed a network of Unix machines, HPs, Suns and UnixWare.

Responsibilities included office productivity, hardware and architecture maintenance along with software and protocol installation.

Additional responsibilities included researching, evaluating, advising, prioritizing and implementing new initiatives to improve system performance.

Worked on company-wide processes and procedures for standardizing administration of server systems with primary focus on the clusters used in DCAC/MRM. Due to the nature of the three tier architecture and how HA clusters generally operated if the database cluster, or any middle layer clusters failed over, it created undesired side effects throughout the system.

Focused on understanding all the dependencies and interrelations of the DCAC/MRM system and how the cluster fail overs impacted those relations.

Developed a test to clarify the dependencies, and relations to determine what changes could be made to the Cluster Configurations or other related software to better support a transparent Cluster failover.

Provided production support for AT&T Wireless Axys system.

Axys system consisted of over 5,000 Unix machines: NeXTstep, HPs, Sun, Silicon Graphics and PCs located nation-wide.

Prior to production releases of Axys, performed system and integration tests to evaluate the readiness of the next release targeted for production. This included configuring HA servers, installing and configuring sybase databases, installing and configuring Axys software in preparation for system and integration testing.
