Rafael Ferro González

Senior Software Engineer at Blocks, working on cloud cost optimization (FinOps) across AWS and Google Cloud.

I design and build the backend services, data pipelines and infrastructure behind a multi-cloud FinOps platform. Most of my work sits where distributed systems, cloud infrastructure and applied AI meet: turning raw billing and usage data into accurate, actionable savings recommendations.

Focus areas

  • Backend and data platforms: Python and FastAPI services, ETL pipelines and analytical data stores for cost analytics at scale
  • Multi-cloud engineering: extending an AWS-native product to Google Cloud, including billing data, access models and customer onboarding
  • Platform and reliability: infrastructure as code, Kubernetes, GitOps delivery, and observability with actionable alerting
  • Applied AI: LLM-backed recommendation systems with validation built in, and AI-assisted development workflows for engineering teams

Toolbox

Area Technologies
Languages Python, TypeScript, Go, PHP
Backend FastAPI, Node.js, NestJS, Symfony
Frontend React, Next.js
Cloud AWS, Google Cloud
Infrastructure Terraform, Kubernetes, Argo CD, Docker
Data and observability ClickHouse, PostgreSQL, Grafana

How I work

  • Clean Architecture and Domain-Driven Design, with clear boundaries and testable use cases
  • Event-driven systems with explicit, versioned contracts
  • Everything as code, from infrastructure to dashboards and alerts
  • Small, reviewable changes, with architecture decisions recorded as ADRs
