About

Senior DevOps/SRE Engineer with 15+ years operating infrastructure spanning legacy systems to Kubernetes, GitOps-driven CI/CD, and full observability stacks. I build resilient, self-service platforms on AWS and GCP, provisioned and managed through Terraform, that help engineering teams ship faster while meeting SLOs and reducing MTTR.

Trilingual (Portuguese, English, Spanish), with experience ranging from vendor engagements supporting global telecom operators (Vodafone, América Móvil, Telefónica), to a direct engagement embedded at Pinterest, to high-growth startups across Cybersecurity, HR Tech, and AI.

Career log

Feb 2026 — present current
Senior DevOps Engineer
Nimbus AI Technologies · Berlin, DE
  • Migrated infrastructure to Terraform, eliminating configuration drift and establishing a fully version-controlled, auditable baseline for PostgreSQL- and Kafka-backed services.
  • Built VPC networking, peering, and routing with AWS ALB-based DNS and TLS termination, hardening the platform's network security and connectivity.
  • Migrated CI to GitHub Actions and adopted Kustomize for Kubernetes config management and EKS Auto Mode for node autoscaling — enabling self-service deploys and parallel builds that cut release friction across teams.
  • Replaced Datadog with an open-source observability stack (Grafana, Prometheus, OpenSearch, Tempo, OpenTelemetry) and centralized secrets in AWS Secrets Manager — cutting monitoring costs by 60% while improving audit compliance.
  • Mentored 9 team members on DevOps tooling and workflows, strengthening the team's DevOps culture.
Jan 2025 — Feb 2026
Senior Site Reliability Engineer
PowerUs · Berlin, DE
  • Migrated the platform from DigitalOcean to AWS, introducing Kubernetes and Helm with HPA and Karpenter-based node autoscaling to standardize deployments and improve reliability.
  • Configured VPC networking, peering, and routing with nginx-based ingress, TLS termination, and Route53 DNS — closing latency and security gaps across the network layer.
  • Replaced DroneCI with GitHub Actions and adopted ArgoCD for GitOps-based deployment, increasing release frequency from ~10 to 200+ per month.
  • Implemented Datadog monitoring across Kubernetes and RabbitMQ, plus a Zero Trust network model via Cloudflare with secrets centralized in HashiCorp Vault — reducing incident response time and strengthening security posture.
Mar 2022 — Dec 2024
Senior DevOps Engineer
Perseus Cyber Security · Berlin, DE
  • Optimized infrastructure and PostgreSQL configuration, decreasing application deployment and start-up time by 40%.
  • Established VPC networking, peering, and routing with nginx-based ingress, TLS termination, and Route53 DNS for a consistent, auditable network architecture.
  • Implemented automated certificate self-renewal via HashiCorp Vault, eliminating manual cert management and expiry-related outages.
  • Standardized CI pipelines on GitLab CI and Helm for Kubernetes deployments, with HPA to handle variable workloads.
  • Automated backup/restore routines and built custom monitoring with the ELK stack, Grafana, and Prometheus.
Aug 2021 — Jan 2022
Senior DevOps Consultant
Direct engagement embedded at Pinterest (B2B contract via BairesDev)
  • Led automated deployment of weekly production releases, implementing a git branch-cut and code-freeze process that reduced deployment time and increased release accuracy.
