Owning end-to-end validation and release readiness for cloud-native 5G SA/NSA features on the CommScope OneCell platform (now part of Andrew, Amphenol). The OneCell platform is deployed across 3–5 Tier-1 global carriers in enterprise and outdoor small cell scenarios. What I do day-to-day: → Owned end-to-end validation and release readiness for 10+ features across 5G SA/NSA on the OneCell platform partnering with Product Management, Systems Engineering, and Development on roadmap prioritization, scope decisions, and customer-deployment trade-offs. → Drove deployment-readiness for cloud-native gNB on Kubernetes validating CU-CP, CU-UP, and DU disaggregated architectures for the OneCell platform. → Translated 3GPP specification updates (Release 15/16/17) into actionable platform requirements influencing internal prioritization across carrier aggregation, EN-DC, EPS Fallback, Emergency Call in 5GS, RRM, NRT management, UE-ANR, PWS, and CUUP flow control. → Led complex multi-interface platform validation across F1AP, E1AP, NGAP, X2AP, and Radio interfaces identifying and remediating critical pre-release defects to ensure conformance and stability for production rollout. → Authored test strategy and end-to-end test plans for SA/NSA features (256 QAM, ENDC call processing, DMS, self-healing, smart reuse, MAC scheduler, SRS, HARQ, RACH, measurement gap) ensuring conformance for multi-vendor interoperability, a core Open RAN deployment requirement. → Mentored junior engineers and led cross-functional reviews with Development, Systems, and Customer Support teams across geographies. Technologies & frameworks: 5G SA/NSA, O-RAN architecture, Kubernetes-based gNB deployment, F1AP, E1AP, NGAP, X2AP (EN-DC), S1AP, RRC, MAC, RLC, PDCP, 3GPP Rel-15/16/17, Wireshark, JIRA, Linux.

Spent nearly four years at Mavenir the world's leading telco-first, cloud-native, AI-by-design network software vendor, serving Tier-1 carriers globally working on the IPA LTE Small Cell platform (S60/E40, S60Z, E61, E62). What I worked on: → Drove feature integration and validation for cloud-native LTE small cell platforms shipped to Tier-1 global carriers owning customer-impacting features across SON, SRVCC, CSFB, MOCN, Network Listen, Dynamic Backhaul Management, and Handover (S1/X2). → Led on-site customer integration in Cambridge, UK for VoLTE, CSFB, and SRVCC deployment bridging Engineering, Customer Support, and Field teams to deliver carrier-ready integration in a multi-vendor LTE/UMTS/GERAN environment. → Owned validation of carrier-monetization, TCO, and production-deployment features Soft Frequency Reuse (SFR), CSG, ETWS/CMAS, dedicated bearer establishment, paging optimization, OpenAir API integrations, IPSec, CRL, static IP commissioning, and forced handover scenarios. → Collaborated with Product Management and Customer Success across multiple geographies and carriers this is where I started building the cross-functional, customer-driven product muscle that now defines how I think about the role. Why Mavenir mattered for me: it's where I learned that strong telecom products are built at the intersection of protocol depth, customer empathy, and cross-functional execution not in isolation.

Two years working on the NG4T Core Network Emulator across LTE, 3G, and 2G technologies providing simulation support to testing and integration teams, and acting as the primary escalation interface to NG4T (Germany) for advanced root-cause analysis and feature gap escalation. This was where I first learned how to translate field-escalated issues into product-improvement requests a discipline that has shaped how I think about platform validation ever since.

About

I build cloud-native RAN platforms for a living and I've spent eleven years working at the engineering–product interface, deciding what gets validated, what ships, and what trade-offs make customer deployments succeed. For the past four years at Andrew (Amphenol), I've owned end-to-end validation and release readiness for 10+ features across 5G SA/NSA on the OneCell cloud-native small cell platform. Before that, I spent four years at Mavenir the world's leading telco-first, cloud-native, AI-by-design network software vendor working on the IPA LTE Small Cell platform deployed across Tier-1 global carriers, including on-site customer integration in Cambridge, UK. I just completed an Executive MBA at IIM Udaipur because I'm increasingly drawn to the product strategy and platform leadership side of what I do. The most interesting questions in AI-RAN, Open RAN, and Telco Cloud are no longer purely technical they're about which features ship, which trade-offs win customers, and where AI/ML genuinely adds value vs. where it's noise. Areas I think and write about: → Cloud-Native RAN platform architecture (CU-CP, CU-UP, DU disaggregation) → AI/ML application in RAN operations and conformance → Open RAN multi-vendor interoperability and platform productization → 5G SA/NSA protocol depth : F1AP, E1AP, NGAP, X2AP, RIC, xApps/rApps → Kubernetes-based gNB deployment and cloud-native operations I'm always open to conversations with people working on AI-RAN platform strategy, Open RAN productization, Telco Cloud architecture, or anyone thinking about how 3GPP Rel-18/19/20 AI/ML work shapes operator economics. Reach out : I learn most through dialogue.
