About

I’m Roger Dávila, a DevOps/Cloud Engineer and Solutions Architect with 11 years in tech and 6 in DevOps. My path started in Java development, moved through data warehousing and solutions architecture, and evolved into DevOps and Platform Engineering. I build secure, resilient, and cost-effective cloud platforms with a pragmatic, business-driven mindset.

Most recently I served as the sole DevOps/Platform Engineer at a RegTech startup, owning the entire platform for multiple development teams — from EKS infrastructure and CI/CD to observability and security. I thrive in environments where autonomy, ownership, and cross-cultural communication are essential.

Key Skills

Cloud & Infra

AWS multi-account architectures with Organizations, IAM Identity Center (SAML/SCIM via Google Workspace), and cost optimization strategies.

Platform & Kubernetes

EKS platforms from scratch: Helm, namespace-per-tenant isolation, PDBs, NetworkPolicies, External Secrets, Cluster Autoscaler with IRSA.

CI/CD & Automation

GitHub Actions pipelines for build, test, scan, and deploy. Automated tenant onboarding with Terraform modules + GitHub Actions.

Security & Compliance

IAM least-privilege, image scanning, SSL/TLS, policy enforcement, centralized identity management, and secrets rotation.

Experience

  1. DevOps / Platform Engineer — RegTech Startup 2024–2025

    • Sole platform engineer; owned the entire infrastructure serving multiple dev teams.
    • Built AWS EKS multi-tenant platform from scratch: namespace isolation, NetworkPolicies, External Secrets, GitOps.
    • Reduced EKS cluster from 11 to 8 nodes through utilization analysis (CPU ~8.5%, memory ~30%), implemented Cluster Autoscaler via Terraform with IRSA.
    • Automated tenant onboarding end-to-end with Terraform modules + GitHub Actions.
    • Centralized identity: integrated Google Workspace with AWS IAM Identity Center (SAML/SCIM), eliminating manual user provisioning.
    • Observability baseline with Datadog: health probes, structured logs, and SLO dashboards.
    • Drove platform adoption across multicultural teams through enablement sessions, documentation, and developer-friendly tooling.

  2. Cloud Engineer — Millicom 2022–2024

    • CI/CD at scale with GitHub Actions, AWS CloudFormation, incident and vulnerability management.

  3. Software Engineer — SMX Services & Consulting 2020–2022

    • Jenkins pipelines, unit testing, code reviews, enhancements on existing systems.

  4. Previous roles (Accenture, Ecaresoft, Banorte, Softtek) 2014–2020

    • Solutions architecture, platform engineering, data warehousing, web development.

Featured Work

Multi-tenant EKS Platform

Built from scratch: namespace-per-tenant isolation, NetworkPolicies, External Secrets, Helm + GitOps. Served multiple development teams across several tenants.

EKS Cost Optimization

Analyzed node utilization metrics, reduced cluster from 11 to 8 nodes. Implemented Cluster Autoscaler via Terraform with IRSA and designed a rightsizing strategy with Compute Optimizer and Graviton analysis.

Centralized Identity & Security

Integrated Google Workspace with AWS IAM Identity Center via SAML and SCIM, eliminating manual provisioning. Enforced IAM least-privilege, image scanning, SSL/TLS, and policy enforcement.

Automated Tenant Onboarding

End-to-end automation with Terraform modules + GitHub Actions: infrastructure spin-up, secrets provisioning, deploy pipelines, and namespace configuration.

Observability Foundation

Datadog-based observability: health probes, structured logs, SLO dashboards. Explored open-source alternatives with Prometheus/Thanos, Grafana Loki, Tempo, and OpenTelemetry Collector.

Platform Adoption & Change Management

Standardized DevOps practices across multicultural teams without formal authority. Shifted from control-based to enablement-based approach: training sessions, documentation, and tooling that made the right path the easy path.
