Engineering Portfolio — Abhinav Shrivastava

Abhinav Shrivastava

Senior Software Engineer · Cloud Infrastructure · IBM PowerVC · 2017 – 2026

Nine years designing and shipping production infrastructure software on IBM PowerVC — an enterprise private cloud platform built on OpenStack, managing virtualised workloads across IBM Power Systems hardware for Fortune 500 data centres globally. Primary domains: storage driver engineering (SAN arrays, FC zoning, multi-path I/O), VM lifecycle management (HMC, NPIV, vSCSI), and feature architecture (bulk operations, image pipelines, performance optimisation). Directly investigated and resolved production incidents for 18+ enterprise clients at P1/P2 severity — root-causing storage driver failures, FC zoning regressions, VM lifecycle breakdowns, and upgrade regressions under live-environment pressure.
