julayo@dev:~$ whoami
Senior DevOps / Platform Engineer with 10+ years building and running enterprise CI/CD and cloud infrastructure — in banking and high-volume e-commerce, where deploys have to be boring and failures are expensive.
AWS Certified Solutions Architect. Deep with OpenShift/Kubernetes and a broad delivery toolchain (Harness, Jenkins, UrbanCode, TeamCity, CodePipeline). I also run production-grade AI infrastructure at home — GPU model serving, GitOps, mesh networking.
I'm also a dad, which taught me ruthless prioritization: no ceremony, no complexity that doesn't earn its place. I got into DevOps because I hate doing the same thing twice — if it's tedious and repetitive, automate it.
Based in Santiago, Chile 🇨🇱 — open to senior IC roles, remote-friendly for teams in the USA or LATAM.
Infrastructure & CI/CD
Three real systems I designed and run. Every diagram below reflects something live in production — not a whiteboard sketch.
1 · julayo-dev.com — AWS static site (all IaC)
This CV, defined entirely in Terraform: a private S3 bucket served through CloudFront (Origin Access Control), auto-renewing ACM cert, Route53 DNS. Deployed by CodePipeline → CodeBuild.

2 · delete-from.com — keyless CI/CD (OIDC)
Zero long-lived credentials: GitHub Actions federates into AWS via OIDC and assumes a scoped role at deploy time. Static hosting on S3 + CloudFront.

3 · Homelab — 3-node GitOps platform (on-prem)
One repo as source of truth across a workstation/AI server, a NAS and a public VPS. Nodes deploy by pulling from Git — no manual changes. 5-copy redundancy, Caddy + TLS, Tailscale mesh over CGNAT.

Key skills
- CI/CD across a broad toolchain: Harness, Jenkins, UrbanCode Deploy, TeamCity, GitHub Actions (OIDC), AWS CodePipeline & CodeBuild.
- AWS infrastructure: S3, CloudFront, ACM, Route53, IAM, VPC, Lambda, CloudWatch.
- Infrastructure as Code with Terraform (reusable modules, remote state) and Ansible.
- Containers & orchestration: Docker, Kubernetes, OpenShift, Helm.
- Automation & scripting in Python, Bash and Groovy for build, deploy and toil removal.
- Platform & networking: Linux, Caddy, Tailscale, TLS/OIDC, secrets management, observability (Prometheus/Grafana).
