SKILLS SUMMARY

• 20+ years experiences on UNIX and network protocols, especially about Linux and BSD derived systems, IPv6, and DNS.
• Solid knowledge and experiences of research and development of Internet protocols, Communication systems, and Operating Systems.
• Unix system installation, administration, and programming.

WORK EXPERIENCE

Principal Software Architect, Infoblox, Inc., June 2018 - present

• Designing and implementing cloud-based DNS-DHCP-IP address management services on a Docker/Kubernetes based micro service architecture. Mainly focusing on the design and implementation of network protocols for these services and gRPC based inter-service APIs.
• Reviewing and designing network protocol implications for cross organization projects.
• Continuing most of the responsibilities in the next section.

Principal Software Engineer, Infoblox, Inc., July 2013 - May 2018

• Developing protocol enhancements on DNS server appliance products: initial design and documentation, main development, test and debug, and assisting post-release maintenance. Mainly as an individual project contributor, sometimes leading projects. Major projects include multi-master support, DDoS mitigation, Geo-IP support, cloud-based DNS firewall, and cloud-based IP management system.
• Contributing to open source projects, mainly to ISC BIND and NLnet Labs unbound DNS servers, by submitting feature patches and bug reports.
• Representing Infoblox at the IETF: authoring and reviewing internet drafts at working groups related to DNS, DHCP, and IPv6. Also serving as an Internet Area Directorate member.

Senior Software Architect, Internet Systems Consortium, Inc., January 2008 - June 2013

• Design and implementation of the BIND 10 DNS server: API and server software design and implementation; R&D for server performance enhancement.
• Design and implementation of the BIND 9 DNS server, focusing on performance enhancement and improving attack resilience.

Research Scientist, Corporate Research & Development Center, Toshiba Corporation, July 2001 - December 2007

• (2007) Served as a program co-chair for the ACM SIGCOMM 2007 Workshop "IPv6 and the Future of the Internet"
• (1998 - 2006) Research and development on IPv6 at the KAME project: Designed and implemented various fields of IPv6 on BSD-variant OSes.
• (2001 - 2006) Collaboration research with ISC: Contributed to ISC's latest DNS software, BIND9, upgrading the support for IPv6, improving overall server performance, and enhancing robustness in terms of security.
• (1998 - 2007) Represented Toshiba at the IETF: attended all IETF meetings since March 1999, proposed 10+ Internet Drafts on the area of IPv6 and DNS, and published 4 RFCs.

Engineer, Corporate Research & Development Center, Toshiba Corporation, April 1995 - July 2001

• (1995 - 1998) Research and development on fast forwarding technologies using ATM cell switching (a prior work toward MPLS)
• (1996 - 1998) Developed BSD-based IPv6 network protocol stack from the scratch.
• (1998, 1999) Served as a member of Network Operation for Networld+Interop Tokyo Center (NOC): designed and operated IPv6 network in the convention backbone. Established the base of full support for IPv6 in the convention network.
