Radio Free Asia
Sr. Network & Software Engineer, Technical Operations
- Involvement in a wide range of Linux systems and IP network
deployment and management efforts as well as software development of
internal and external web applications to support RFA's mission of
delivering uncensored news and information in nine native Asian
languages: Chinese Mandarin and Cantonese, Korean, Tibetan, Uyhgur,
Vietnamese, Lao, Khmer, and Burmese.
- Involvement in Internet circumvention efforts to allow target country entities to gain access to communications channels and resources such as the Internet and other telecommunications systems that are blocked or censored by foreign governments.
- Involvement in network, system, and information security efforts to protect RFA assets and information from attacks from entities hostile to RFA's mission.
- Significant involvement in wide ranging network and systems design, deployment and migration efforts with extensive automation (Python/Perl) of information gathering and reporting for planning phases as well as deployment and monitoring along with development of automated intrusion prevention mechanisms and custom automated access controls.
- Converted RFA's proprietary NEC digital phone system (300 desktop
phones) to primarily VoIP based system, including integration of
remaining T1/ISDN/POTS lines. Integration with Telos VX studio phone
system (20+ studios), and various ISDN/POTS gateways
(MediaTrix/Grandstream). Network and systems design and deployment with
high availability/fail-over routing and PBX on CentOS/HP. Implemented
with Asterisk opensource PBX. Developed Python/Perl tools for
automated/bulk provisioning, configuration and QA of IP phones.
Integration with remote offices in Bangkok, Phnom Phenh, Hong Kong and
other locations providing no cost calls to those offices, and outdials
from those locations to numbers local to those sites. Built custom
interview recording solution along with web interface to recordings with
authentication integrated with voicemail PIN. Full replacement of
prior PBX features, including Voicemail, conferencing, FAX, special
analog setups, hunt groups, paging, weather hotline, etc.
- Developed server imaging system for automated server install and
configuration of the systems involved in the VoIP deployment. Any of
these machines can be automatically rebuilt from scratch to their prior
running configuration with no human intervention in about 15 minutes via
a modified/simplified ISCONF infrastructure management suite. Essentially a combination of PXE/DHCP/DNS/make/rsync and CVS. Built associated PXE/TFTP/DHCP/DNS servers and incorporated centralized syslogging. Integrated with enterprise firewall (Stonegate) dhcp-relay/VLAN design.
Developed web based, multi-language news gathering platform to aggregate
feeds from news agencies: Xinhua News Agency, Reuters, AP, AFP and
others to provide a central resource for RFA's editorial staff.
Includes ingest of disparate feed sources via FTP, IMAP, RSS, NewsML,
along with advanced multilanguage search and features such highlighting
of search terms in paged results. Python language, with Sphinx
documentation, and MySQL backend.
- Developed an integrated system for segmenting and transmitting RFA's live broadcast channels via HTTP Live Streaming (HLS)
using opensource tools. The platform picks up Axia IP Audio live
broadcast sources on a Windows (Axia Linux driver no longer available)
virtual machine running on a CentOS KVM host, which is then served with
Icecast. A Linux Ubuntu guest VM running ffmpeg takes the Icecast
source inputs and feeds them through Carson McDonald's opensource
live_segmenter and tools to generate MPEG-2 Transport Stream segements
and related extended M3U playlists.
- Developed a virtual-machine based, broadcast audio archiving system
using above mentioned technologies, as the organization's Telos
Audioactive hardware archivers are failing after years of use.
Simultaneous recording at multiple sample/bit rate combinations allows
one virtual machine to replace multiple hardware devices. Developed web
interface to audio archives.

- Develop tools for automated router-config
generation and modification to support network upgrades, maintenance,
and grooming, including large scale customer moves onto higher density
hardware, full router chassis migrations (Juniper M160 to T640 moves),
