Site Reliability Engineer / Principal Software Engineer @ Deploy Cloud Foundry using BOSH. Git, AWS, Ruby, Go, Bash, SSH, OpenSSL, VMware, OpenStack Cloud Foundry is part of Pivotal Labs. From March 2014 to July 2014 (5 months) San Francisco Bay AreaBay Area Solar Construction Intern @ * Inspect roofs for suitability to install PV panels * Organize tools & parts inventory to streamline field work * Install panels From March 2013 to June 2013 (4 months) System Administrator, Electrical and Software Engineer @ I joined QuickPay because they did not have a System Administrator, and because my electrical engineering skills were essential to diagnose and solve problems with wi-fi and cell phone signal propagation. Adapt gate-arm hardware (e.g. Magnetic Autocontrol MIB30) for internet payment. Troubleshoot antenna problems in basement structures. From May 2012 to June 2012 (2 months) SDK Support Engineer @ - Support our SDK customers, who are in the business of making Digital TVs, Settop Boxes, or Network-Attached Storage (DTV, STB, NAS) units. Our customers, in turn, take their products to cable providers, retail outlets, etc. Macrovision changed its name to Rovi in the summer of 2009. From October 2007 to May 2011 (3 years 8 months) Manager, Software Development @ - Manage a group of 5-8 experts in audio & video systems software in the C language for streaming MPG, AVI, etc. From October 2006 to September 2007 (1 year) Senior Software Engineer @ I designed, wrote, and maintained object-oriented utilities to manage components of the Genesis(R) product (which uses Oracle SQL, Solaris OS, Java, Perl, Windows, XML, HTML, PDF). Offered knowledge of certain best practices to less experienced programmers. Fixed many bugs in various chains of shell scripts, in three separate dialects of unix shell: sh, csh, ksh. Wrote code in Perl to back up and restore data and then double-check that the right files were restored. Auto-generated HTML (based on perl code) and small "seed" information for a Sun E450's disk drives/controllers for field reporting. Took over several additional responsibilities as the company shrank, e.g. when the principal engineer who had worked on the Analysis Engine of the Genesis Enterprise System (which used Java, C++, IDL and Corba) left, I took over development of those components. Perl/GD/CGI system monitoring project Design, write, debug and implement a system monitoring system with the following attributes: * Use off-the-shelf, open source components. * Collect data on disk traffic, network traffic, CPU usage, available memory / page scan rate, and load average at regular intervals, using standard Solaris commands. * Allow these data to be graphed using GD::Graph in a CGI environment. * User can choose the date range and which graphs are shown. Invalid dates are not allowed and the user will be asked to provide valid dates. * Old data is automatically deleted to avoid clogging up the file system. Continuing Education: * Attended Java classes at night * Attended Allen Holub's Object Oriented Software seminars * Attended Sun's System Performance Tuning XML Used XML Schema (rather than DTD) to specify XML format for large (~ 6Gb) data files I also used XML Spy to validate verify, search, etc. Oracle 8.1, Oracle 9.2 Solaris 5.7, Solaris 5.8, RedHat Linux 7.3 Environment: Windows XP with Exceed From April 2002 to October 2006 (4 years 7 months) Senior Software Engineer @ Design and implement Object-Oriented Perl code with an Oracle SQL back end for customized web sites in the traditional advertising industry. Swan Systems brought powerful collaboration tools to the web, specifically for the top advertising companies in the world. Using Oracle and Perl, we developed multiple sites where ad companies could collaborate by digitizing the ad company's proposed commercials for the client. This was important, because in 2000, it was still common practice for an ad company to FedEx video tapes to their clients for viewing. I taught myself Perl and wrote useful modules at Swan: * Many time-related conversion routines for converting between "epoch time" and human time. * A time-based Event object type, with start and end times (Unix format), or a flag to indicate an "all day" event. * A universal time zone system - We tracked time-sensitive data such as the date and time a particular TV show would air. The general problem: use binary search through one time zone's table to look up the correct offset (standard GMT offset +/- DST), then convert that new sum into another forms as needed. * I tackled a real instance of the "U1E9" problem: when Unix time rolled over from 999999999 to 1000000000, some events "disappeared" from the calendar - these values were stored as strings, not numbers. The solution: make sure that code that sorted or compared these values did so with a numeric comparison. * We also had a calendar system that could take advantage of the Event and Time Zone modules. I did not work on its design or implementation at first, but once I started working on the Calendar code, I noticed a number of bugs that I fixed. Over a couple of months, I just about re-wrote the Calendar code, and added some optimizations. One thing I think I did to impress the QA manager was to know my own code so well that I could fix my bugs quickly - often the same day as they were reported, or even within a few minutes. From July 2000 to July 2001 (1 year 1 month) Senior Software Engineer @ Software Engineer (Glide Software, April 1999-June 2000) Wrote Glide graphics API code in C for the Voodoo3/4/5 product line of graphics accelerators, and added or extended these features: * Do no harm to existing code base. * Searched for and flipped all arrays referring to mipmap levels that required C array indices to be used "upside down", like "mip_map_level[8-i]" * Added 32-bit ARGB support to Glide, which had only 8- and 16-bit before. * Added 4-bit FXT1 support to Glide. * Added support to Glide for textures with dimensions of 512, 1024, and 2048, where 256 had previously been the largest. * Added new Glide tests for these features. Managed Glide and OpenGL software teams through the ramp-up for Voodoo4 & Voodoo5. Assigned bugs and kept the workload balanced throughout the team. Reported progress in daily phone conferences. Wrote completely automatic early-warning nightly make system to proactively catch errors & distribute reports to team (makes were done on Intel Windows 9X machines; reports were sent to UNIX system and then compared with previous night's results and filtered for any negative compiler messages). This helped to avoid wasting valuable development time across multiple person-hours. Software Engineer (MS Windows Control panels / Localization, October 1998 - April 1999) Managed corporate-wide Localization for all software products. Localized 3dfx control panels for Banshee, Voodoo2, Voodoo3 product lines into French, German, Spanish, Dutch, Italian, as well as Japanese, Korean, Chinese in MSVC with MS resource files and C++ code. Write C++ Windows "tray app" to handle switching Glide libraries for customers with multiple products. Added new features to control panels for TV Out functionality. From October 1998 to June 2000 (1 year 9 months) Software Engineer @ - Write Object-oriented Intel Assembly language software for PCs, palmtops, PDAs, smart phones, etc. - Studied Japanese so that I could better understand the particular project I was working on. - Acted as tech lead and shipped three products at once: UK, Dutch, and German versions of one of our US-based machines. - Write software for the GEOS-SC system (C language with object-oriented extensions) such as a email retrieval system for a phone. I know that these are very common now, but in 1998 we were ahead of the cutting edge. From January 1995 to June 1998 (3 years 6 months) Senior System Administrator @ I was Geoworks' first full-time System Administrator in 1991. I began what was later to become the MIS group. I was in charge of all Unix-related system maintenance, company-wide for a while, until the team grew. Set up all Unix systems, Novell NetWare systems, administered Cisco routers, PBX system, wired up new offices as we expanded, flew to customer sites to set them up using our development system. Consulted with several phone and network vendors and worked out technical details, chose which compan(ies) to hire to install phone and ethernet for about 200 people in our new office building. Put together the new servers that we were to take to the new building ahead of time, and physically move the servers and disks myself to the new site, and set them up. We moved all of those people's equipment and the main company servers in one weekend, on time. At 8:00 am Monday, all central MIS systems were up and running, because of the level of detail and planning I was able to bring to the project. From January 1991 to December 1994 (4 years) Member of Blue Maintenance Crew @ From June 1990 to September 1990 (4 months) Co-op Engineer @ - Joined the Silicon Quality group and assessed their IT needs. - At that time, Intel did not have a corporate-wide LAN at all. Each PC stood completely alone and lots of paper documents were passed around and lots of data was re-entered. - Intel had a plan to deploy a LAN but it took time to implement. I went in and installed systems ahead of that effort so that my department could reap some benefits without waiting further. - Set up an SCO Xenix system with RS-232 terminals and fiber optic VGA terminal lines to workstations. - Trained users in basic UNIX procedures. From January 1989 to December 1989 (1 year) Resident Assistant @ Keep an eye on a few hundred college kids who still lose their keys, etc. From August 1987 to May 1988 (10 months)
