Eduardo Santiago

Created, enhanced and maintained hundreds of Perl, C, and shell software tools used in engineering development environment. Tools ranged from user-visible to transparent; from daily simple operations to infrequent complex CVS merges; from command-line to web-based via CGI and mod_perl. Continuously monitored tool performance and mailing list chatter to refine and enhance existing tools and to discover what new tools were in need of inventing. Assisted in site system administration of Solaris and Linux hosts. Analyzed existing DNS setup for entire internal domain, created new framework for maintaining DNS with a simple hosts file and one config file. All named.conf and domain zone files are now generated and maintained automatically, with no need for humans or for maintaining duplicate data. Created new scheme for managing accounts, consolidating login, email, automount, and employee ID in one central file instead of four hand-maintained ones.

Created CGI interfaces to the Sybase defect and project tracking systems. Developed new web interfaces to existing data, creating simple ways to visualize complex datasets. Where possible, found automatic ways to hyperlink relationships between disparate (but related) databases. Designed graphs illustrating software branch relationships and activity, and developed ways to generate automatically and daily. Designed plots for monitoring defects/features. Created an entire tool suite for managing software review. Integrated with defect database, CVS repository, mailing lists. Set up tests to analyze diffs and catch common problems automatically.

Automated software build environment. Automated software release process, encoding complex decision trees into a simple web interface requiring just a few human decisions. Automated the build calendar. Automated the CVS branch creation process. Wrote tools for compile farm: Created client/server architecture for running user jobs but handling interrupts, exceptions, I/O, and local needs better than rsh/ssh. Learned SQL in order to work with existing Sybase environment. Wrote dozens of small tools and reusable modules to perform periodic maintenance and cross-checks. Eliminated most tasks that required human SQLing, by creating scripts for all common (and some uncommon) procedures. Designed and set up MySQL database for tracking feature requests; wrote new interfaces and tools for managing and updating those requests.

Investigated bugs in gcc cross-compilers. Investigated migration path to newer gcc. Created new SNMPv2 toolkit for handling MIB module maintenance.

Wrote C and IDL software for analyzing data from ACE, Ulysses, Lunar Prospector, Deep Space One, IMAGE, and Genesis space exploration missions. Updated and/or rewrote scientific software in order to make portable and add features. Automated all processing of incoming telemetry and data. Designed graphical plots of instrument data, and wrote software to generate these automatically. Developed simple interfaces to these routines. Created automated WWW interfaces to supply mission data to worldwide scientific community. Investigated algorithms for generating useful information from raw data. Evaluated spacecraft health telemetry and designed methods for flagging suspect data. Wrote code for performing statistical analyses of the solar wind. Wrote IDL procedures to generate daily summary plots for new data, as well as special-case plots for publication or grant proposals. Created core set of reusable data analysis modules.

Created a clean C/IDL interface to the UDF data format library, allowing scientists on the IMAGE mission to access their data with ease. Developed a simple-to-use IDL library for performing coordinate transformations between physical frames of reference. Developed a software system for interfacing IDL to SPICE (a JPL toolkit for providing spacecraft ephemeris). JPL is now (2006) including my system with their SPICE toolkit.

Responsible for the maintenance and administration of a Convex C3240 system controlling a Metrum RSS600 tape jukebox. Educated users in best ways to use jukebox. Developed tools to assist in its regular maintenance and auditing. Was also responsible for the operation of over one hundred mixed Linux, SunOS, Solaris, and IRIX workstations spread out over three physical networks. Developed tools for handling backups, host table generation and checking (e.g., to keep the central DNS registry up to date), new account and mail alias generation, automount map creation, disk space monitoring. Acted as webmaster for internal and external servers.

Working in a team of four, ported the Auspex NetServer software to an AIX platform. Moved source base for this project from RCS to CVS. Wrote tools to assist in source control and management. Wrote OpenBoot-based driver code used in bringup of new multifunction I/O processor board. Developed and maintained internal bug-tracking tools. Wrote e-mail and CGI front ends (in 1993). Wrote a graphical tool used for finding peoples' offices in new building. Prototyped, set up and implemented Auspex's first WWW presence.

Designed, specified and prototyped new powerup/firmware environment. Designed and implemented set of tools for managing hardware design releases. Ported parts of OSF/1 kernel to new platform. Wrote tools for coworkers throughout the site. Wrote tools to manage my workstation, and acted as local Ultrix contact. Designed diagnostic architecture for DECstation 5000 line. Implemented diagnostic suite for CPU, cache, memory, I/O subsystems. Developed CPU and network diagnostics for MicroVAX 3000 systems. Assisted in initial debug of CVAX processor chip. Wrote tools to simplify and automate diagnostic development.
