At Bloombert, I build platform capabilities that make delivery faster and more reliable across 30 AWS accounts. I designed Terraform/Terragrunt modules that cut provisioning time by 40% and refactored Jenkins pipelines to reduce median build time from 28 to 9 minutes. I also built a Go API for ephemeral QA test clusters, reducing setup from hours to 12 minutes, and improved CI reliability with Docker-based test sandboxes. My OpenTelemetry and ELK/Kibana work helps teams detect deployment regressions sooner. Previously at PwC, I owned CI/CD for data pipelines, increased daily deployments from 2 to 12, and reduced batch processing runtime from five hours to 90 minutes. At Globant and Hyland, I built backend services, improved worker throughput and reporting performance, and strengthened operational practices. I enjoy applying systems design and practical automation to help engineering teams ship reliably. I mentor engineers on infrastructure-as-code patterns, contribute to incident response and postmortems, and focus on secure, observable cloud systems.
