What I'm looking for

I’m looking to lead GSMA-aligned eSIM/roaming product strategy, drive platform automation and intelligent decisioning, and partner with engineering and MNOs to grow revenue—using KPI-driven optimization to scale globally.

I’m a Senior Product Manager with 14+ years driving eSIM, IoT, and telecom platform innovations within GSMA RSP ecosystems (SGP.02, SGP.22, SGP.32). I build and scale global eSIM products across automotive, consumer, and IoT segments—enabling connectivity across 30+ countries and multiple Tier-1 MNOs.

At Tata Communications, I own the product vision and roadmap for an eSIM IoT RSP orchestration platform aligned with GSMA standards. I lead end-to-end lifecycle management, partner with sales/engineering, run customer workshops and demos, and continuously enhance RSP capabilities to meet enterprise and operator requirements.

I’m known for accelerating MNO onboarding, improving platform performance, and delivering customer-centric innovations at scale—delivering solutions for automotive OEMs including JLR, BMW, and Stellantis. Earlier, I supported GSMA-certified eSIM integrations, reduced integration time by ~30%, improved platform uptime to 99.9%, and cut incident resolution time by ~40%—with deep expertise in roaming validation, steering readiness, and telecom signaling (MAP, CAP, Diameter).
