Offer

Platform and product. Shipped to production.

Azure and AWS. Observability, GitOps and digital product. Same bar: production, evidence, handover.

01

Azure & AWS cloud

Landing zones, Kubernetes and governance. Azure as home; AWS at the same level when the workload already lives there.

  • CAF, subscriptions, Entra ID, Key Vault, Policy, Defender, Monitor
  • Private AKS, ACR, Velero, Private Link, Front Door
  • AWS: EKS, ECS, IAM, VPC, CloudWatch, Secrets Manager (eu-south-2)
  • Terraform, Terragrunt, Bicep, versioned modules and DR
02

Observability & SRE

Actionable signal and measurable MTTR. Not a vanity dashboard.

  • Prometheus, Grafana, Loki, Tempo, Alertmanager, Thanos
  • OpenTelemetry, ELK / OpenSearch, Azure Monitor, App Insights
  • Datadog, New Relic — when the client already has a contract
  • SLI/SLO, DORA, runbooks and cardinality under control
03

CI/CD & GitOps

Repeatable, auditable releases — no heroes at the keyboard.

  • Azure DevOps, GitLab, GitHub Actions, Jenkins → modern target
  • Argo CD, Argo Rollouts, Helm, Kustomize, Flux
  • OIDC, environments, Checkov, Trivy, OPA in pipeline
  • Backstage / IDP, Crossplane and Terraform Cloud by maturity
04

Product and security

SaaS, e-commerce and compliance at the same delivery standard.

  • Next.js, TypeScript, Node, PostgreSQL, Prisma, MongoDB, Redis
  • Vercel, Supabase, Stripe, i18n, business dashboards
  • ISO 27001, GDPR, CIS, Kyverno, Falco, Snyk, Defender
  • Audit with remediation: closed findings, not a PDF

Method

Short, explicit, with a success criterion.

01

Discovery

30–45 min. Risk, debt and quick wins. If we are not a fit, I say so on that call.

02

Proposal

Scope, deliverables, out-of-scope and metrics (deploy, MTTR, compliance). Fixed-scope or part-time retainer.

03

Delivery + handover

IaC, pipelines, evidence and runbooks. Success is operations not needing me for the day-to-day.

Next step

If the platform hurts, let’s talk.

One call. If there is no fit, I say so there. Independent in Málaga, clients in Spain and the EU.
