Independent Architecture Perspective
Irfan M / Principal Enterprise & Security Architect
More than 27 years across enterprise technology, infrastructure, and information security, spanning Fortune 500 scale and highly regulated industries. The work pairs architectural strategy with hands-on engineering: setting the target state, choosing the control patterns, and staying close enough to delivery to keep the design honest.
Each engagement is framed around business risk, defensible controls, and operating reality, then communicated in terms executives and engineering leaders can both act on.
