Hi, I'm Valente 👋

Infrastructure & Platform Engineer — I build and run production blockchain platforms for regulated finance.

For ~5 years I've worked on the UK's flagship wholesale-banking blockchain programmes — including Fnality, backed by the Bank of England — turning Hyperledger Besu, Ethereum and FireFly into compliant, observable, highly-available systems, and automating the cloud infrastructure beneath them.

🔗 What I do

• Blockchain platforms — Hyperledger Besu, Ethereum, FireFly, web3signer, Blockscout, Solidity. Stood up a production network end-to-end in six weeks.
• Infrastructure as Code — reusable, best-practice Terraform modules for EKS clusters and the AWS estate around them.
• Kubernetes & delivery — EKS / GKE / AKS, Helm, Harbor, and secure, auditable CI/CD (GitHub Actions, GitLab).
• Security & PKI — highly-available HashiCorp Vault, cert-manager and CloudHSM; full certificate-lifecycle automation for critical banking systems.
• Observability — Prometheus, Grafana and OpenTelemetry across blockchain environments.
