Kartik Subbarao’s Summary

I am an information technologist with a strong track record of delivering innovative, cost-effective solutions with open standards and open source-based components. I've worked in large IT organizations and consulted for several Fortune 500 companies, taking new ideas from concept to production.

I contribute regularly to communities of practice, and have led teams with members from all over the world. I have helped colleagues achieve breakthrough goals in professional development. I look to build a culture of organizational learning wherever possible.

I believe very strongly in the power of Information Technology to transform our work and our lives in a meaningful and positive way. If you find that my work, skills or interests overlap with your goals, I would like to explore potential opportunities for collaboration.

Kartik Subbarao’s Experience

Consultant

Independent

(Information Technology and Services industry)

February 2009 — Present (6 months)

Independent Consultant, Writer and Speaker
Enterprise Architect

Hewlett-Packard

(Public Company; HPQ; Information Technology and Services industry)

January 2007 — January 2009 (2 years 1 month)

Open Source and Linux evangelist promoting strategic and holistic use of emerging technologies to transform customer IT environments. Presented numerous briefings to customer IT executives, as well as conducted in-depth workshops on topics including:
• Open Source IT infrastructure services (e.g. Directories, Mail/Messaging, Collaboration and Security), architecture and stack migration
• Optimizing people and process management in the context of Open Source technology and its breakthrough capabilities/cost structures
• Open Source as a foundation for Web 2.0 / Enterprise 2.0
• Best practices for working with Open Source companies
• Building an internal community of practice around Open Source
• Open Source and Business Transparency

In this role, I was responsible for defining session content and recruiting top industry speakers for HP's premier open source customer event, the Open Source Advisory Council (OSAC).
Open Source and Linux Profession Global Lead

Hewlett-Packard

(Public Company; HPQ; Information Technology and Services industry)

January 2005 — January 2009 (4 years 1 month)

Founding Global Lead for HP's companywide community of practice for Open Source Technologists. Increased the number of Open Source practitioners in HP, improved the professional development of its members, led engineering working groups to accelerate open source usage/contribution, and increased thought leadership around Open Source in HP and beyond. Highlights:
• Organized a seminar series ("Tux Talks") and hosted presentations/discussions with industry luminaries
• Developed technical infrastructure for an open standards-based (SMTP/LDAP/NNTP/RSS) directory-integrated collaboration environment based on Sympa, OpenLDAP and INN
• Led the development of an open, integrated social software environment for HP based on WordPress MU (blogs), Pligg (crowdsourced voting), and the collaboration software mentioned above.
Master Technical Consultant

HP IT

(Public Company; HPQ; Information Technology and Services industry)

January 2004 — December 2006 (3 years)

Promoted to Master level on HP's Technical Career Path, and asked to take on a broader role. Responsible for architecting/engineering Core Computing IT services encompassing Directories, Messaging, Collaboration, Naming and Security. Highlights:
• Initiated and led the development of the IMAP Proxy service, to provide secure access to HP email from anywhere on the Internet. With over 68,000 self-registered users and overwhelmingly positive feedback citing productivity breakthroughs, IMAP Proxy is one of the most successful services deployed by HP IT. Using entirely open source software accessible by standards-based clients, it also has one of the lowest support costs of any HP IT service.
• Initiated and led the development of the HTTP Proxy service, to provide secure access to HP web sites and other resources from the Internet. Using entirely open source components, HTTP Proxy is estimated to save $1M+ in annual licensing/support costs over comparable proprietary solutions.
Directory Services Architect

HP IT/Services

(Information Technology and Services industry)

November 1999 — December 2006 (7 years 2 months)

Primary owner for strategy, architecture and technical direction of HP's Enterprise Directory and Extranet Directory. Highlights:
• Transformed HP's Enterprise Directory into a standards-based LDAP directory that has become one of HP's mission-critical IT systems. Also developed synchronization software and auxiliary services for the directory infrastructure.
• Migrated HP's Enterprise Directory to OpenLDAP on Linux, making HP quite possibly the first Fortune 11 company with a 100% Open Source production Enterprise Directory (serving over 50 million operations daily). Greatly increased technology capabilities while reducing operations costs by several hundred thousand dollars.
• Core member of the "clean room" team that integrated HP's and Compaq's directories during the merger. The seamless directory integration on day 1 of the merged company was cited as a major success story.
