Acton, Massachusetts, United States
Experienced Software Architect with expertise in technical research, software architecture, development and support. Passionate and result-oriented leader who has built and led cross-functional and global teams which deliver quality solutions in a timely manner. Designed, built, delivered and supported multiple products which are/were deployed at various Tier 1 operators around the world. Specialties: SS7, SIP, VoIP, WiFi, SON, carrier-grade products, Embedded Platforms, software scaling and performance improvement.
In my journey from the first Engineer/Hire (for the company) to the Director of the team responsible for Wifi(Access and Backhaul), LTE-backhaul and SON I was responsible for the initial software platform bring-up, 1st LTE cell bring-up with UE, 1st wifi and lte backhaul connections setup, the 1st mesh setup amongst other things. I also setup the 1st build system which supported PPC/arm/x86/MIPS targets. I have awarded multiple patents in the diverse fields including WiFi, LTE, Mesh technologies, traffic shaping etc.
As the manager of the team responsible for WiFi and backhaul development I led the team responsible for developing MaxMesh (patented) which dynamically managed traffic routing over a secure wifi backhaul with sub-1s convergence for lost links. We subsequently built a new protocol which enabled dynamically adding wired nodes (with wireless connections) to each wireless site with automatic determination of local vs remote nodes.
As the first Engineer/Hire to join Parallel Wireless I started as an MTS and was responsible for the initial software platform bring-up, 1st LTE cell bring-up with UE, 1st wifi and lte backhaul connections setup, the 1st mesh setup amongst other things. I also setup the 1st build system which supported PPC/arm/x86/MIPS targets.
GENBAND acquired Cedar Point in January 2011. As a result of this acquisition Safari development was off-shored. I was part of a small team of people retained to aid in the transition of the product to the new team, and to support and develop new features while the new team ramped up. I was responsible for the SIP and SS7 subs-systems for the same. I was the Technical Lead for the Flexible Message Manipulation Feature for S3, the company’s SBC product. This feature aimed at manipulating the SIP message and the associated ISUP and SDP bodies. The goal is to achieve better interoperability and policy enforcement between various network elements. I led a small team across 3 countries for the same. There were 3 patents filed(pending) based on the work I did on the FMM framework long after I left, where I am listed as the co-inventor for initial solution architecture.
I was the lead architect and developer for the Cedar Point SIP solution. I led a small team of engineers responsible for the development and support of the same. I was also one of the key contributors towards the TGCP based MGC offering. I provided technical guidance on all architectural, design and field support involving SIP, SS7, TGCP, PBX, Call Processing, Media management and also the next-generation 3GPP IMS networks. I worked closely with cross-functional teams involved in the development of the product roadmap as well as providing support for customer deployments.
Aastra acquired the Network Access Division (Aptis) from Nortel in 2002. I was one of the very few engineers retained to support and further develop both the CVX and the CVX-SS7 gateway. The work involved strong knowledge of SIP, VOIP and SS7.
