About me

I'm a DevOps and Cloud Engineer based in New York, NY, passionate about building infrastructure that is reliable, secure, and frictionless for development teams. My background in accounting gave me a deep appreciation for precision and structured thinking — skills that translate directly into designing airtight systems.

Over the past five years I've worked in fintech and financial data, managing production Kubernetes clusters on EKS, architecting GitOps workflows with ArgoCD, and provisioning AI infrastructure on AWS Bedrock. I believe that if something is done manually more than once, it should be automated.

Some technologies I work with regularly:

Kubernetes & Docker
Terraform & Ansible
AWS · GCP · Azure
GitHub Actions & Jenkins
ArgoCD & GitOps
Prometheus & Grafana
HashiCorp Vault & Doppler
Bash & Python
