  • Shyp
    Vp Engineering
    Shyp Sep 2016 - Jul 2017
    San Francisco, Ca, Us
    Took over all of engineering (consisting of ~35-40 people) as we were started to move to a more B2B focus with SMB. This involved integrating with third party shopping carts such as Shopify and Magento. Much refactoring of the Node platform was required to pull this off, and we also brought in React for use on the new consumer website. I managed the HQ engineering teams (platform and mobile) and several offshore or remote teams for special projects such as the Magento integration and improvements to our Business Intelligence systems.

  • Pivotal Labs
    Consultant
    Pivotal Labs Jul 2006 - Jan 2008
    San Francisco, California, Us
    Known now as VMware Tanzu Labs, but née Pivotal Labs. Pivotal was and still is considered perhaps the best Agile consultancy to come out of San Francisco. We practiced a strict version of agile development known as eXtreme Programming. This disciplined approach and quality of my colleagues set a high water mark for feature deployment velocity and low bug count that I have been pursuing ever since.Famously, when Twitter needed to fix their Fail Whale problem, they called in Pivotal Labs.Worked on projects for a dozen or more startup clients, and also on two internal products:- One was a Rails framework that provided all of the standard building blocks for the contemporaneous state of the art: user system with login support, messaging and other social features. We were able to jump start client projects with this system to enable rapid MVP deployment.- The other was Pivotal Tracker, now a publicly released project management tool based on XP Agile processes. Tracker was at the time one of the most advanced web apps around in its use of would become "Web 2.0" technologies with things like in-browser drag-n-drop UX. We created an internal equivalent of jQuery before jQuery had come into wide usage.Technology: Ruby on Rails and Javascript. 100% Test Driven Development, Pair Programming most of the Agile practices that have now become commonplace.

  • Synthematix, Inc
    Chief Software Architect, Founder
    Synthematix, Inc Nov 2000 - Nov 2004
    Synthematix built enterprise software for laboratory chemists which allows them to track, analyze and interact with chemical reaction information in a structured format. In other words, we built the first professional electronic lab notebook in a time when almost all chemists were still using paper and ink notebooks, and institutional knowledge was not indexed/searchable. Typical customers were pharmaceutical companies and chemical suppliers. I was extensively involved in almost all technology related aspects, from making the Ethernet cables and building the intranet, firewall and our self hosted Internet servers, to hiring developers, project management, mentoring, designing the application, selecting or building development tools, and coding a significant portion of the products. Named on the patent for our IP. Synthematix has been acquired by Symyx Technologies, Inc., now Accelrys (ACCL).Built a system solo in 3 intense months that earned $250k from one customer by reducing the user time for a molecule database search (an NP-complete problem) from 5 minutes to under 2 seconds. Ask me how!Technology: Java, PostgreSQL, Oracle and all sysadmin work.
  • Verizon Wireless
    Senior Programmer
    Verizon Wireless Oct 1997 - Nov 2000
    Basking Ridge, Nj, Us
    Designed and built applications used by the Network Operation Centers to track cellular network performance. Created an innovative logging system for these internal applications that stored rich metadata, and allowed including with bug reports. This allowed my team to replay user interactions within another tool I created to visualize user actions and underlying system actions side by side along with map visualization when appropriate. Use of this tooling system greatly reduced time to fix bugs and increased insight into user behavior allowing for better design. I have made use of this concept many times with subsequent projects. In a way this was a precursor to the best practice of instrumenting apps to gather user usage data.Technologies employed include Solaris, Java (AWT, RMI, JNI to C, JSP/Servlets, JDBC), Apache HTTPD and Informix RDBMS. Also worked with C, Oracle, perl, and Unix administration utilities.
