1999-2001: Senior Developer, Disappearing, Inc. / Omniva Policy Systems, San Francisco, CA

Designed and implemented secure, high-performance, highly available email server software using C++, Java, SSL, SNMP, JDBC, and Sybase on Linux and Solaris.

I designed and implemented the following aspects of the Omniva server:

Nonblocking queued architecture capable of handling thousands of simultaneous clients using only a handful of threads; the queued design protects against deadlocks.
Crashproof stable queues providing stable storage within a single keyserver, and serving as the basis for crashproof mirroring of keyserver contents to hot remote servers.
Stackable protocol code allowing HTTP tunnelling and/or SSL encryption (using OpenSSL) of client sessions.
A custom SNMP agent (using UCD-SNMP) providing keyserver and mirror health monitoring.
An SNMP subagent library and a custom MIB compiler generating C++ wrapper objects to make SNMP coding easier. Released as open source; see www.kegel.com/snmp.
