ArgentinaWhat I'm looking for
At NerdRabbit, I lead DevOps automation using Pulumi and Python to create reusable infrastructure and deployment templates across AWS services including Lambda, ECS, SQS, Kafka, VPC, IAM, and ELB. I also build AI-enabled workflows with AWS Lambda, Claude, Nova, Flask, Botpress, DynamoDB, and agent prototypes.
Previously at JPMorgan Chase & Co and IBM, I led backend and DevOps initiatives spanning Kubernetes, Terraform, CI/CD, system automation, database migration, and large-scale data ingestion. I enjoy mentoring teams in programming, DevOps practices, object-oriented programming, and automation while turning operational blockers into practical engineering solutions.
