Wellington, New Zealand and Santa Rosa, CA
Advanced Software Development Engineer
Leading a small team to develop a web-based healthcare business intelligence tool.
While at Futrix and — post-acquisition — HDMS, I've been a core member and, more
recently, lead of an agile, results-focused development team. We develop the Java-based midtier
and web UI of a healthcare-focused business intelligence tool, and collaborate closely with the
team implementing the product's query tier.
I've developed features working alone and with others, collaborated closely with Product to
scope possibilities and develop requirements, provided engineering-level tech support,
brainstormed to provide solutions to the day's urgent business requirement, mentored
less-experienced developers, and guided architectural decisions.
Recently, I've been a key driver of efforts to modernize the mature system, with goals of
improving performance and ensuring the system can support the company's needs in the coming
years.
I've focused on infrastructure issues, owned the Spring Security-based authentication stack,
and become the team's "security guy". I'm frequently called on to triage issues, and enjoy
the challenge of efficiently diagnosing root cause.
While most of my days were spent in the Java world, I'm always happy to jump in anywhere,
including the SAS-based query tier and the UI tier using technologies like Vaadin, Spring
MVC, React, and AngularJS.

Wellington, New Zealand
FSS Developer
Worked on team responsible for defining and integrating telephony services
provisioning solutions for a major telephony operator. Product was
responsible for orchestrating complex communications to multiple
network devices using communications protocols such as SOAP.
Major components of the solution included Oracle database and PL/SQL,
Weblogic application server, and
Axiom
AXiOSS service fulfillment platform.
Gained understanding of IMS telephony network architecture by interacting
with various network elements.
Worked to develop PL/SQL code code quality checker (à la C lint or Java
checkstyle), using ANTLR parser-generator tool.
Worked on Java-based web application to drive the SOAP-based
PSA interface, for use as internal
development and test tool. Technologies used include JavaServer Faces/JSP,
Apache Axis, and xmlbeans.
02/2003 - 07/2007
Petaluma, CA
Senior Software Engineer
Developed software for a Java-based network management
application as part of a highly-dynamic, internationally-distributed,
and agile development team. Quickly learning technologies such as
the JBoss Application Server, Eclipse RCP, Spring, and Hibernate, I
was able to contribute to the complex core of the product within
a short period of time.
Independently learning about Subversion and the Maven build tool, I
successfully brought order and speed to what was formerly a chaotic
and highly-time-consuming release process.
Served as software technical lead for a major embedded development
project; the product was an extension to a legacy telecommunications
platform which bridged the gap between the TDM and packet domains
using
CES.
Developed software for a new embedded telecommunications platform.
Owned a subsystem responsible for management of and communication to
peripheral equipment. A notable challenge was the need to accommodate
various idiosyncrasies of legacy hardware and software that could not
be changed.
Implemented a data redundancy mechanism meeting requirements of a
highly-available system.
Increased my knowledge of the vxWorks RTOS, Motorola PPC and 68K,
Motorola QUICC, Flash device drivers, HDLC, IP protocols, XML/XSL
and ORBs.
Westwave Communications
06/2000 - 12/2002
Santa Rosa, CA
Software Engineer
Modified an existing Digital Loop Carrier to enable its
operation as a media gateway, allowing for dynamic connection
management by an external Media Gateway Controller.
Implemented an SNMP agent interfacing on the back end to a
relational database.
Designed and implemented an automated software distribution
subsystem to allow for easy field upgrade of distributed hardware
components.
Gained knowledge of Class 5 switching concepts.
07/1997 - 12/1999
Petaluma, CA
Co-op Student/Software Engineer
Gained knowledge of Digital Loop Carriers and associated
communications topics. Areas studied include BRI ISDN, SONET, TR-008,
GR-303, TR-057, and Transaction Language 1 (TL1).
Projects included strengthening of the top-level equipment
protection switching code, work with provisioning of SONET
cross-connections, creation of a system alarm log, general OAM&P
work, customer field response, and offsite interoperability
testing.
DSC Communications Corporation
07/1996 - 03/1997
Plano, TX
Co-op Student/Software Engineer
Worked on call processing software for a large tandem switch.
Gained knowledge of call routing methodologies, SS7, and Dynamically
Controlled Routing (DCR).
