About

I am telecommunications and 3GPP professional with 16+ years of experience in 5G, 4G/LTE, IMS, EPC, MVNO, cloud-native infrastructure, networking, virtualization, performance engineering, system integration, and customer-facing technical support. Over the last 10+ years in the U.S. telecom market, I have supported major operators including AT&T, T-Mobile, and regional carriers such as PTCI and Pioneer, delivering carrier-grade solutions across deployment, integration, validation, optimization, and production support. My expertise spans 5G SA/NSA, O-RAN, 5G Core, IMS/VoLTE/VoWiFi, EPC, MVNO architectures, SIP, Diameter, RTP, TCP/IP, Linux, Kubernetes, OpenStack, KVM, and cloud-native technologies. I have extensive experience integrating O-RAN CU/DU with 5G Core networks and validating key interfaces including F1-C, F1-U, N2, N3, and N6 through functional, interoperability, scale, and performance testing. I have designed and validated 100G to 200G+ throughput environments, built cloud-native testbeds using AWS and Kubernetes, and led performance, resiliency, and capacity testing for telecom and security platforms. My experience also includes network dimensioning, capacity planning, CIQ preparation, solution reviews, HLD/LLD development, infrastructure sizing, and deployment architecture. I have worked extensively with Dell PowerEdge servers and virtualization technologies, including NUMA tuning, CPU pinning, SR-IOV, DPDK, huge pages, BIOS optimization, and NIC tuning to deliver high-performance, low-latency telecom solutions. Core strengths include Telecom Solution Architecture, 3GPP technologies, MVNO integration, protocol analysis, root-cause analysis, performance engineering, Tier-2/Tier-3 support, cloud-native platforms, multi-vendor interoperability, and customer engagement. CCNA, CKA, and KCNA certified. Actively interested in Telecom Solution Architect, 5G Solution Architect, Cloud-Native Network Architect, Technical Consulting, and Pre-Sales Engineering opportunities, leveraging deep telecom expertise to deliver scalable, resilient, and production-ready solutions.
