I wrote control software for custom voice conferencing telephony bridges, using C++, Perl, Java, C#, Ruby, and shell scripting. I took primary ownership of the end-user-facing web interface and the core threading, networking, and serialization framework.
- Rewrote the application's built-in web server, using heavily-tested core code to replace poorly-tested special-purpose code.
- Refactored the core threading, message-passing, serialization, and networking infrastructure to support new use cases, including pluggable serialization formats and transport protocols, and dynamic address registration.
- Worked with telephone companies to support carrier-specific low-level telephony protocols.
Bachelor's of Computer Science equivalent.
