.Mac Notifications
(lightweight distributed messaging system)
MacOS X 10.4 (Tiger), C, Java, XML-RPC, WebDAV
Implemented client and server sides of an architecture
which provides the ability for a client
process on MacOS X 10.4 (Tiger) to securely send arbitrary
light-weight messages (notifications) through .Mac to other interested processes running on
other systems. (In effect, extending MacOS X's CFDistributedNotificationCenter model to the
internet.) This is technology behind the "publish and subscribe" features in the
.Mac SDK 2.0
announced at WWDC 2005.
The client is a CoreFoundation framework coupled with a UNIX daemon which communicate via
XML-RPC with a .Mac server.
The notification "server" is a persona of Apple's powerful and flexible .Mac WebDAV server
implementation which receives
XML-RPC, accesses the WebDAV-based message registry, and coordinates with .Mac's custom DNS server to
distribute notifications to remote observers.

SyncServices WebDAV protocol for .Mac
MacOS X 10.4 (Tiger), Objective-C, WebDAV
Designed and implemented and Objective-C framework which layers synchronization and transactional semantics over the standard WebDAV protocol.
This protocol is used by Mac OS X 10.4 (Tiger)'s .Mac System Prefs panel to securely store data on .Mac's iDisk WebDAV servers
without requiring a .Mac Synchronization Management server.
This improves the scalability of the server side while reducing overall complexity and leveraging open
standards and protocols.

iSync Synchronization Management Server for .Mac
MacOS X, Apache, Tomcat, Oracle 8i, SQL, Java, XML
Lead the small team which implemented the high performance Java-based synchronization management server which powers Apple's .Mac iSync
synchronization service (Mac-to-Mac over the Internet) with a very aggressive schedule. Designed and implemented RDBMS schema and data access framework.
Created functional specifications for the server and its XML API. Integrated the synchronization accounts/service with other web-based
services offered by .Mac subscription service.

fusionOne SyncML Synchronzation Server
Windows NT, Oracle 8i, SQL, Java, HTTP, SyncML
Implemented key features in a SyncML synchronization server. Features included: Java servlet implementing session support and HTTP authentication, device
capabilities exchange, multiple messages,
authentication & security, and C++
SyncML utility classes.
Provided feedback (on the specification and SyncML Reference Toolkit) to the SyncML working group during the development of the SyncML
specification (version 0.8 through 1.0.)
In April 2001, this server became one of the first certified "SyncML-compliant" servers.

Senior Software Engineer
fusionOne SyncML Reference Client
EPOC, SyncML, HTTP
Implemented critical features for a cross-platform synchronization client
core which uses the SyncML protocol. Features included: multiple messages, logging, authentication,
and device capabilities exchange. This client
core has been ported with minimal effort to the EPOC OS, BREW,
& *NIX, as well as an embedded application licensed to prominent manufacturers of mobile phones.
In April 2001, this client became one of the first certified "SyncML-compliant"
clients (making fusionOne one of only 2
companies supplying both a SyncML client and
server at that time.)

fusionOne Filtering XML Synchronization Server
Windows NT, Oracle 8i, SQL, XML
Improved fusionOne's XML sync server
(which uses the proprietary SyncAPI) to support the ability
to manage a subset of the records in a
user's fusionOne account (in this case, for a Sprint-branded service powered by fusionOne.)
This service went live to Sprint PCS
customers in September 2001.
