I build reliable delivery pipelines and scalable cloud platforms. 3+ years shipping Kubernetes platforms, Terraform-based IaC, and SLO-driven observability. I focus on reproducibility, developer experience, and security by default.
- Leading and hands-on in platform/infrastructure: from greenfield IaC to production-ready Kubernetes with GitOps.
- Currently: building an Internal Developer Platform (IDP) and driving end‑to‑end DevOps adoption across teams.
- Collaboration: infrastructure bootstrapping, DevOps process optimization, platform reliability, and technical consulting.
- Designed multi-environment Kubernetes platforms with GitOps, policy-as-code, and progressive delivery (canary/blue‑green).
- Automated cloud infrastructure with Terraform cutting config drift and reducing MTTR.
- Implemented supply‑chain security (SBOM, signing, vulnerability scanning) and secrets management.
- SLO/SLI instrumentation with actionable alerting and dashboards to improve on‑call quality.
- IDP blueprints: self‑service app, reusable CI/CD workflows, golden paths for teams.
- DevSecOps: shift‑left scanning, image signing, SBOM, policies in CI/CD.
- Observability: metrics/logs/traces, SLO error budgets, and alert routing that reduces noise.
- Containers & Orchestration: Kubernetes, Helm, Argo CD, Argo Rollouts
- IaC & Automation: Terraform, Ansible
- CI/CD: GitLab CI, semantic-release
- Observability: Prometheus, Grafana, Loki, OpenTelemetry, Alertmanager
- Security: Trivy, Snyk, OPA/Gatekeeper, Vault
- Cloud: AWS (EKS, ECR, IAM, VPC), GCP (GKE, GCR), Azure (AKS, ACR)
- Languages: Bash, Python, Go (basics), YAML
- Reduced lead time to production with preview environments and automated quality gates.
- Increased deployment safety using canary and blue/green strategies with metrics‑based promotions.
- Lowered alert fatigue by introducing SLO‑driven alerts and targeted routing.
- Standardized Terraform modules to accelerate onboarding and minimize drift.
- Simple, composable architectures over accidental complexity.
- Everything as code: infra, policies, dashboards, and runbooks.
- Measure what matters: SLOs, error budgets, latency and reliability first.
- Secure by default: least privilege, secrets management, continuous scanning.
- GitOps workflows with clear promotion paths (dev → stage → prod).
- Modular Terraform, validated inputs, environment isolation, and CI checks.
- Declarative Kubernetes with Helm templating.
- Observability-first: golden signals, tracing, incident review loops.
