DevOps Engineer at Brainly

March 1, 2024 - October 9, 2025

Owned a managed Kubernetes platform (EKS/GKE) with Terraform and Helm/Argo CD; blue/green for major changes and canaries for risky deployments. Built fast CI/CD with GitHub Actions, Docker layer caching, per-PR preview environments, enabling small, frequent releases. Established centralized observability (Prometheus, Alertmanager, Grafana) with OpenTelemetry traces; defined SLOs and burn-rate alerts to reduce MTTR. Centralized logs with Fluent Bit -> Elasticsearch/OpenSearch (PII redaction, ILM tiers); optimized retention to reduce costs. Reliability tuning (HPA/VPA, PodDisruptionBudgets, topology spread) and smarter bin-packing to lower node count without tail latency impact. Security defaults (mTLS, least-privilege IAM, OPA/Gatekeeper, Trivy, SBOM, cosign). Disaster recovery with Velero backups and runbooks for drills. Collaborated with Go/Node teams on readiness/liveness probes and API contracts; created a platform golden path to accelerate new service setup.
