Timeline

Professional evolution

A track record of designing, supporting, and optimising AWS infrastructure — including the honest gap I took for family and a small business.

2025present

Brazil

Independent — Amazon FBA & Family

Self-employed / Career break

Stepped out of full-time employment to run a small Amazon FBA e-commerce business and to be present for family. Honest break, intentional decision.

  • Operating a small Amazon FBA store end-to-end: sourcing, listing optimisation, P&L, returns and customer support.
  • Built operational dashboards in spreadsheets and lightweight automation to track inventory, costs and margins.
  • Using the time to keep AWS skills sharp — building public portfolio projects (serverless e-commerce, Terraform-on-AWS, k3s microservices, CI/CD) and maintaining certifications.
  • Currently looking to return to full-time engineering — open to Cloud Engineer / DevOps roles in Ireland, the UK or remote across the EU.

Halian Sàrl

Cloud Engineer / DevOps

Designed and implemented production AWS infrastructure for enterprise clients, working in a cross-functional team across architecture, DevOps and platform engineering.

  • Designed reference architectures for new workloads on AWS (VPC, ALB, ECS, RDS) and documented them as decision records.
  • Built reusable Terraform modules and CI/CD pipelines so platform teams could provision environments self-service.
  • Owned operational documentation — runbooks, architecture diagrams and onboarding guides.
  • Collaborated with security and networking teams to get designs approved against client compliance requirements.
