About me

Let me introduce myself.

Profile Picture

I'm Corentin, a DevOps & Cloud engineer based in Barcelona. I help teams stop running cloud “by hand”: reproducible infrastructure with Terraform and clearer cloud spend (FinOps) on GCP and AWS. Side consulting available outside my full-time role (~10–15 h/week, async-first).

Profile

Cloud engineer (~3 years). Technical referent on multi-cloud infra, Terraform standardization, CI/CD and cost-aware operations. Strong at handoffs and mentoring (teaching background). FR / EN / ES.

I don’t take energy-flexibility / demand-response style projects (employer conflict).

Technical skills

  • IaC & FinOps: Terraform (modular), Ansible, CloudFormation; cloud cost / billing awareness
  • Cloud & orchestration: GCP (GKE, serverless/containers), AWS (EKS, EC2), Kubernetes, Docker
  • CI/CD & ops: Jenkins, GitHub Actions, Bash, Python, Linux; monitoring (GCP Ops, CloudWatch)
  • Collaboration: Git, GitHub, Jira, Confluence · mentoring / technical referent

How I work

  • Consulting fit: Clear scope, async handoffs, deliverables over staffing
  • Technical referent: Mentoring engineers and standardizing infra practices
  • Communication: Explain complex infra simply
  • Ownership: Prioritization and follow-through on platform work

How we can work together.

Side consulting · deliverables & milestones · ~10–15 h/week · async-first

Cost & IaC Audit

1–2 weeks · cloud + Terraform readiness review, basic risks and FinOps findings, plus a 30/60/90 roadmap.

Entry: from ~1.200–1.500 €

Terraform Sprint

2–4 weeks · modular Terraform, environments, CI basics and a documented handoff your team can own.

Entry: from ~2.500–3.500 €

Retainer

10–15 h/month · async reviews, small FinOps/IaC improvements, one short sync per week max. Not 24/7 on-call.

Entry: from ~900–1.100 €/month

Custom / other formats

Need a different shape? Fixed-scope project, short B2B contract, or a hybrid next to Terraform / FinOps / platform IaC (GCP or AWS). We define deliverables, hours and price together.

Portfolio

Open accelerators & anonymous case studies.

FinOps Dashboard

Context: teams can see cloud spend in native consoles, but still lack an execution layer for waste, ownership, and next actions.

Problem: cost reviews stay reactive; opportunities are not ranked, owned, or easy to demo without live billing credentials.

Actions: built a Google Cloud–first accelerator: CSV → metrics/snapshot, public Pages product story, local Grafana evidence pack, adapters and runbooks for later multi-cloud.

Outcome: portfolio-ready FinOps narrative visitors can click through; same path usable as a client starting template.

Stack: GCP · Python · Prometheus · Grafana · GitHub Pages

Live demo · GitHub

EKS Landing Zone

Context: AWS Kubernetes baselines are often rebuilt from scratch per engagement, with uneven security and ops defaults.

Problem: time-to-first-cluster is slow; private networking, IRSA, Karpenter, and platform add-ons rarely land as one coherent accelerator.

Actions: shipped a template-first Terraform landing zone: remote state, private VPC, EKS + OIDC, Karpenter, ALB / External Secrets, CI validate, milestone-tracked roadmap.

Outcome: reusable AWS EKS starting point — configuration-driven onboarding, validated IaC without requiring a live (paid) cluster for proof.

Stack: AWS · EKS · Terraform · Karpenter · Helm · GitHub Actions

GitHub · Roadmap board

01 · Modular Terraform on GCP

Context: B2B SaaS product infra growing faster than the IaC layout.

Problem: duplicated Terraform, weak conventions, hard to scale environments safely.

Actions: refactored toward reusable modules; defined shared infra/code conventions; improved environment layout and handoffs for eng teams.

Outcome: clearer ownership, faster reuse of modules, platform easier to extend without copy-paste drift.

Stack: GCP · Terraform · CI/CD

02 · Multi-cloud ops referent

Context: high-traffic digital platform on AWS + GCP + Kubernetes.

Problem: infra questions and incidents bounced across teams; scaling was partly manual.

Actions: acted as technical point of contact; automated provisioning/scaling with Terraform & CloudFormation; coached teams on day-to-day platform practice.

Outcome: less operational toil, more repeatable scaling, single clear escalation path for infra.

Stack: AWS · GCP · Kubernetes · Terraform · CloudFormation

03 · CI/CD & AWS automation

Context: engineering org needing faster, safer cloud changes.

Problem: pipelines and provisioning slowed delivery; uneven automation quality.

Actions: hardened Jenkins pipelines; automated AWS resources with Terraform/CloudFormation; documented repeatable flows for the team.

Outcome: more predictable deploys and provisioning; foundation for later multi-cloud platform work.

Stack: AWS · Jenkins · Terraform · CloudFormation · Linux
