About
Seeking a remote full-time Cloud Infrastructure, Platform, SRE, or DevOps role. I bring 18+ years in cloud infrastructure, Terraform, networking, DNS, TLS/PKI, load balancing, IPv4/IPv6, CI/CD, monitoring, production deployments, incident response, and on-call customer support. Interested in OCI and India-remote opportunities.
At Oracle, I lead core infrastructure changes that modernize production platforms safely, from peer-reviewed planning through rollout, validation, rollback readiness, and operations.
I've enabled dual-stack IPv6 across approximately 30 locations and delivered a separate five-region rollout, coordinating networking, DNS, certificates, and public load balancing.
I improve identity security and reliability through vulnerability remediation, JDK 17 modernization, JWT dependency remediation, centralized log-access controls, SSO incident response, and monitoring improvements.
My background also includes Java-based test automation and Android product integration, giving me hands-on experience across cloud infrastructure, CI/CD, quality engineering, and mobile platforms.
