About
Security-minded engineer, built on infrastructure
I’m studying for an M.Sc. in Computer Science with a specialisation in cyber security at DTU (2026–), after a B.Tech in Digital Transformation at Atria University in Bangalore (2021–2025).
Before moving to Denmark I worked on Kubernetes, AWS and GCP infrastructure at Elmet.ai and Corover AI: least-privilege IAM, zero-downtime certificate automation across 40+ services, and faster, safer CI/CD. At home I run a Proxmox + k3s lab and a cloud honeypot to learn how real attacks behave.
I’m learning Danish (beginner) and I’m fluent in English. Outside of work I enjoy strategy games and cybersecurity fiction.
