Vina Kumari Roy

I'm a Senior Systems Engineer with 10+ years running mission-critical infrastructure across fintech and healthcare. I started as a Linux Administrator at HPE (AbbVie Pharma), managing ~250 servers and cutting vulnerabilities by 90%. At Cerner, I led a 3-person team supporting 100+ Linux servers as the primary escalation point for critical incidents, improving uptime by 70%. For the past four years at Visa Inc., I've maintained 99.99% SLA/OLA compliance for global payment platforms, led IT Disaster Recovery across authorization and settlement systems, and coordinated teams across the US, UK, and APAC — cutting hardware failures by 70% and security vulnerabilities by 95%.

More recently, I've been applying AI to operations: building an AI-driven anomaly detection model and an MCP/Claude Code-based patching platform that cut patching time by 50%. I hold RHCSA/RHCE certifications plus several in generative AI and prompt engineering. I'm most interested in roles blending operations leadership with AI platform integration.
