Senior SRE and cloud engineering leader with 20+ years building and operating large-scale, self-healing AWS estates, with production depth across Azure and GCP. Industry coverage spans B2B SaaS, agribusiness, EdTech, quick-service restaurant e-commerce and retail banking, delivered hands-on and as manager of distributed cross-border squads. I also author and maintain published open-source infrastructure tooling in Rust and Go.

Currently Senior SRE Cloud Engineer at Viafoura. Full résumé: https://elioseverojunior.github.io

• 243 core applications migrated from legacy KOPS to AWS EKS 1.33 — zero customer-facing downtime via Route53 weighted routing, Argo Rollouts and Istio traffic shifting
• 35% EC2 spend reduction — Karpenter consolidation, ARM64 Graviton node pools and automated spot execution
• ~60% mean-time-to-detect reduction on production incidents — observability codified as infrastructure across Grafana Cloud, Loki, Prometheus, Datadog and OpenTelemetry
• 83% deployment lead-time reduction — quarterly release batches replaced by twice-monthly production delivery

Published libraries and providers, 32,665 downloads combined.

Senior SRE Cloud Engineer — Viafoura · 2024-10 – present

• Led the KOPS to AWS EKS 1.33 migration of the core application estate using Route53 weighted routing, Argo Rollouts and Istio traffic shifting, completing cutover without customer-facing downtime.
• Containerized legacy workloads and authored Helm charts guarded by values.schema.json, rejecting invalid GitOps values before they reach a cluster.
• Provisioned data-lake and analytics infrastructure with Terraform and OpenTofu across Athena, Glue Data Catalog, Redshift, Step Functions and Airflow, applying Lake Formation column- and table-level governance for least-privilege analyst access.
• Codified observability as infrastructure in Terraform across Grafana Cloud dashboards, Loki log pipelines, Prometheus alert rules, Datadog dashboards and label-based Slack routing with OpenTelemetry.
• Standardized multi-account governance with AWS Account Factory for Terraform, Well-Architected guardrails and IAM Identity Center, and migrated legacy Jenkins jobs to declarative GitHub Actions reusable workflows with ArgoCD-centralized GitOps enabling canary and blue-green releases.

Senior SRE Cloud Engineer — Stanza Systems · 2023-10 – 2024-10

• Provisioned secure Amazon SageMaker and Bedrock endpoints with Terraform using scoped IAM execution roles, VPC network isolation and per-workload budget guardrails.
• Maintained multi-environment GitLab CI/CD pipelines enforcing a strict validate, plan and gated apply workflow with Jira ticket-first traceability.
• Tuned Karpenter-based autoscaling and cluster ingress to absorb variable demand without over-provisioning.
• Gated production deployment with SAST scanning, SonarQube quality gates, SOPS-encrypted Helm secrets and ArgoCD sync policies.

SRE Cloud Engineering Manager — Nutrien Soluções Agrícolas · 2022-04 – 2023-09

• Led the LATAM Cloud Engineering cross-squad team supporting downstream software and data engineering squads, building a high-density automation framework rather than growing headcount.
• Architected multi-account hub-and-spoke infrastructure across AWS, Azure and GCP using Transit Gateway, VPC, VPN and centralized identity, consolidating shared data platform services including data lakes, Glue, Lambda, RDS and Redshift.
• Established platform self-service patterns and GitHub Actions reusable workflows that replaced batch releases with continuous production delivery.
• Drove FinOps rightsizing, automated resource lifecycle management and decommissioning, reporting spend directly to the director.
• Mentored senior and junior engineers into end-to-end incident ownership.

Senior SRE Cloud Engineer — Passei Direto · 2021-11 – 2022-04

• Refactored core infrastructure and tuned application performance across AWS VPC, EC2, ECS and Lambda to defend availability under sudden enrolment-driven traffic surges.
• Implemented infrastructure as code with Terraform, Terragrunt and Pulumi, and maintained CI/CD across Jenkins and GitHub Actions.
• Hardened platform tooling including HashiCorp Vault secret delivery, Backstage service catalog and shared Jenkins libraries, instrumenting Sentry error tracking and SonarQube analysis.
