About Mateus
Senior Software Engineer with 12+ years building cloud-native and event-driven systems on AWS and Azure. I focus on Kotlin/Java backends, Frontend with React, Terraform, infrastructure, AI-powered apps and data pipelines.
My goal is to deliver business value, so I enjoy engagements where I can move across backend, frontend, cloud and DevOps to help teams ship end-to-end solutions quickly.

- AI/ML pipelines on Azure AI Services (Video Indexer, Content Understanding, Foundry)
- GitHub Copilot enterprise rollout across teams and repositories
- DevOps: Terraform, GitHub Actions, Jenkins, Kubernetes, Docker
Recent work:
- Built AI-driven video pipelines on Azure for insights, metadata, segmentation and encoding
- Reduced Mirriad's cloud spend by 60% (£330k/year)
- At Mirriad, led the deployment of 100% of cloud resources as Terraform, 100% of builds and deployments on GitHub Actions
- Led the company-wide rollout of GitHub Copilot agents, solving network restrictions, private artefact repos and build reliability
