## Summary
Platform and developer experience engineer with 8+ years across frontend, backend and infrastructure. Currently at Cabify building the Internal Developer Platform as a product; designing tooling, observability defaults and CI/CD pipelines adopted by ~25 engineering teams, with adoption and developer satisfaction as success metrics.

## Experience
### Cabify — Platform Engineer (Jun 2022 – present)
- Built and evolved the IDP using Backstage, including a scorecard system to surface component health (dependency freshness, contribution guidelines, SLO definitions and documentation coverage).
- Built an internal API scaffolding tool supporting REST (OpenAPI/Swagger) and gRPC, generating typed clients and server boilerplate in Go and Elixir; reducing service bootstrap time from hours to minutes.
- Led the company-wide CI/CD standardization initiative: a GitLab CI abstraction layer that shields teams from Bash scripting and low-level configuration details.
- Managed and upgraded ArgoCD (v2 to v3), including identity management and RBAC configuration, Helm chart authoring and publishing to OCI registries, and GitOps workflows across the platform.
- Built and maintained observability defaults using Grafana, Prometheus (Cortex), Tempo and Loki; authored Grafana dashboards from Prometheus metrics and Loki queries, and instrumented distributed tracing with OpenTelemetry across services.
- Maintained event-driven integrations with NATS and Google Pub/Sub over Kubernetes and AWS infrastructure.

### Kairós Digital Solutions, S.L. — Fullstack & Backend Developer (Apr 2018 – Jun 2022)
- Go serverless development on AWS Lambda for Divilo, a B2C fintech app (Lambda, API Gateway, DynamoDB, SQS).
