Developing amazing applications (named in a patent!) involving Machine Learning, Natural Language Understanding and Speech Generation (https://www.interactions.com/product/adaptive-understanding) with audio over SIP.

Doing some very cool video/audio streaming using HTML5/javascript/jquery/nodeJS/FFMPEG/FFPROBE/OpenCV/Max, working with all the big social media players and with a great team of artists and programmers.

Also heading the migration of our large server farm from physical to virtual (VMware ESXi). Using AWS (automated with Puppet) to handle peek loads, saving big on hardware and getting geo-redundancy.

Using C++, Couchbase, 'R', Tableau, Python, D3.js to parse, store, statistically analyze and display performance metrics gleaned from our gigantic server logs. Error rates hover near zero as shown by beautiful real-time graphics. Anything broken is immediately noticeable as an outlier, so is readily fixed.

Lately using Python/Max to inject images/audio into videos at 10x realtime, creating some amazing videos.

I worked SIP on a very cool trunking product at the Chelsea NYC office. Chelsea is a beautiful neighborhood on the Hudson river, filled with great restaurants and of course the amazing High Line park.

Trunking based on Kazoo, a cloud-based VoIP and telecommunications platform. Developed using C++, PHP5 and Kazoo's restful APIs all on Centos VMs.

My career here ended when SIP trunking project was shelved. Disappointing, but I did get to learn Puppet, VMware and SIPP (the SIP test tool) all in an Agile environment.

I am involved in all aspects of telecommunications software development, specializing in SIP, GSM (2G), UTMS (3G) and some interesting streaming audio/video APPs.

Designed/developed/wrote/supported businessgrade softphones with the GUI in html5/css/javascript and the SIP engine implimented in C++ using the PJSIP stack. Interface between engine and HTML was websockets.

I also work with engineering firms, writing interfaces to various embedded controllers using Python and C.

Architect and developer of SIRRAN's GSM, HLR and monitoring/diagnostic tools.

Developed SS7 MAP layer code for SMS/voice handoff between mobile network operator (MNO) and SIRRAN. Wrote a micro HLR and interfaced it to IPAccess picocells. All written in C++ on Red Hat using mysql / sqlite/ pjsip. All this code allowed SMS and voice calls to route seamlessly between PSTN and Sirran's portable 2G networks via SIP.

Hands down the most interesting project of my career. Sorry the project ended, but time to get home to NYC.

A great job in great locations with great engineers, great support and great management. Doesn't get better.
