Experience

  • Contango.xyz — DeFi Perpetuals Trading Protocol
    DevOps Engineer
    April 2025 - Today (1 year and 2 months)
    London, England, United Kingdom
    Joined Contango.xyz as a junior DevOps engineer and designed the entire infrastructure with a team of 3. Stack from scratch: a custom Kubernetes operator in Go Kubebuilder) that acts as the internal developer platform for the whole engineering team — provisioning 30+ services (Kafka, ClickHouse, PostgreSQL, Elasticsearch, Temporal, ArgoCD) from a single CRD, with a dependency-graph engine for parallel deployments and an event-sourced state machine for deterministic audit trails.

    On top of that: a full CI/CD pipeline runner on Argo Workflows, an acceptance testing framework with automatic rollbacks, and all AWS infrastructure as code in TypeScript/CDK across dev, staging, and production accounts.

    Results: code coverage from 18% to 70% through TDD, AWS costs cut by 60% via Karpenter and KubeCost.

    Stack: Go, TypeScript, Kubernetes/EKS, AWS CDK, Argo Workflows, ArgoCD, Prometheus, Grafana, Loki, ELK, Kyverno.
