Personal Profile Summary & Area of Expertise – Lead researcher and Business Development
I hold Ph.D. in computer science and mathematic from the Hebrew University. DARPA (USA) have given me, Ph.D. Thesis award - Optoelectronic Semiconductor Design & Fabrication. I hold B.S.c, M.S.c and MBA from NYU-Polytechnic of NY. I thought several course in the Courant Institute of Mathematic, Tel-Aviv and Hebrew Universities.I worked for over eight year as a researcher on multi-layered optical and packet network routing, optimization, operation and services in AT&T Bell Laboratories.I hold several patents on elastic networks and content integrity.
With strong background in the mathematical and information algorithms for the design of very large wireless and terrestrial undersea fiber optical networks. Over twenty years of experience in business and operational understanding of mobile, telecom, media, security and BSS/OSS process automation.
I'm providing services design and deployment for Huwaei, Amdocs, ECI and Nokia customers (see Figure 1). This includes, per-sales activities, PoCs, system integration, services provisioning, automation, HLD, LLD and DLD documentations review with customers and system development teams. Support for RFQ, RFI and review of standards drafts.
I Lead Mobile Cloud-Native Network Services Solutions. SA SBA 5G network services design and PoC: 5GC vIMS, vSBC, TAS, using SBI to deliver UC to leverage VoLTE, VoNR, ViLTE and IoT for machine to person communications. VNF decomposition to CNF, call flows, network slicing templates and KPIs, microservices CNF packaged in containerized images and orchestrated by Kubernetes and Openstack: EN-DC interworking based on network slice instance that forms a set of network function on sub-network instance. Initial services offerings include voice and video conferencing, eMBB & mMTC. The CNF are monitored & integrated using automated data analytics: AI and ML. Enabling FWA, eMBB, URLLC & mMTC using SBA & MEC CNF distribution.
I manage PoC design to Automated SD-WAN service offering, intent-based cloud-centric control and management policy driven, abstracted edge end-points & orchestration across routing, security, & application optimization domains. Versa & Palo-Alto, Architecture framework. Derive system design documentation, call-flows, provisioning & automation: NaaS & SASE Convergence, VNFs instantiation, advanced security functions: CASB & ZTNA. ZTP, applications dynamic micro-segmentation, service chaining and compliance, abstract edge physical end-points that facilitate management, security, flexibility, portability & automated service management.
I perform data analytics and quantitative modelings for devices and wireless networks to improve device performance, quality, user QoE, QoS. Device analytics and performance, RF performance, device quality, device antenna performance, device readiness. Statistical modeling of wireless network and device QoS/KPI/KQI, user behaviors. Visualize the analytical results using data visualization tools. ML algorithms: forecasting, clustering, classification, reinforcement learning, deep learning. Data extraction/transformation/loading, text mining and statistical analysis using Python, R, Matlab, VBA, Java Scripts. Spark, Hadoop, MySQL, MS Excel, VBA, TeraData SQL, MS SQL
