About Me

My introduction

I’m Rohit, an Infrastructure Engineer in Network Security at Bank of America, specializing in IBM z/OS and enterprise mainframe ecosystems. My expertise spans securing and modernizing mainframe networks through z/OSMF automation, SNMPv3 migration, AT-TLS policy enforcement, IPSec/IKED tunnel hygiene, and TCP/IP stack standardization. In my role, I have enforced SNMPv3-only protocols across all mainframe environments to eliminate legacy vulnerabilities, streamlined AT-TLS deployment via z/OSMF to reduce turnaround times by over 60%, and standardized TCP/IP configurations across 20+ LPARs to improve consistency and cut troubleshooting time. I’ve also automated IPSec rotations, managed certificate renewals to maintain 100% uptime, and designed reusable AT-TLS policies that accelerate rollout while ensuring compliance. Beyond engineering, I have validated z/OS 3.1 upgrades across more than 15 dependent systems and executed DR tests with zero critical failures. My focus is on automation, security, and reliability at scale—ensuring that core banking systems remain hardened, compliant, and resilient.
