Platform & Infra

Platform & Infra

GKE and VM workloads on GCP, provisioned with OpenTofu and Ansible, shipped through GitOps and Helm. Predictable on purpose.

CI/CD & DevEx

CI/CD & DevEx

Reusable GitLab CI templates shared across repos — parallelized and layer-cached, fast enough to stay out of the way.

Secrets, Signal & Cost

Secrets, Signal & Cost

HashiCorp Vault / OpenBao for secrets; Prometheus, Grafana, Loki and Sentry for signal; and a habit of trimming cloud bills without trimming reliability.

02Reusable GitLab CI Templates: 15 → 4 Minute Pipelines

Replacing copy-pasted pipelines with versioned, reusable GitLab CI templates — parallelized and layer-cached — cutting pipeline time ~60% (15 → 4 min) and standardizing builds across repos.

03Centralizing Secrets: Repo Settings → Vault → OpenBao

Moving secrets out of GitLab repo settings into HashiCorp Vault (KV-v2), then to OpenBao after the licensing change — keeping the API contract stable so apps and pipelines needed no rewrite.

04A Self-Hosted Observability Stack on One GCP VM

Standing up Prometheus, Grafana, Loki, and Sentry on a single GCP VM to turn scattered, siloed telemetry into one place to see metrics, logs, and errors — with tracing (OpenTelemetry/Jaeger) as the next step.
