PROFILE

Contributed to the dspace-group/simphera-reference-architecture-aws repository by delivering features that enhanced GPU driver management, S3 bucket lifecycle safety, and deployment reliability for Kubernetes-based workloads. Extended the GPU Operator to support NVIDIA driver CRDs and multi-version management, refactoring modules for explicit driver configuration and improved documentation. Strengthened S3 bucket destruction controls by introducing per-resource deletion protection and safer lifecycle management. Addressed deployment order by enforcing dependencies between Simphera instances and EKS addons, ensuring deterministic provisioning. Resolved a critical bug affecting stateful application deployments by correcting storage class provisioning order. Worked primarily with Terraform, Kubernetes, and YAML to implement infrastructure as code.
