Architect and maintain containerized blockchain nodes on AWS/EKS using Terraform, Helm, and CI/CD pipelines
Operate Bitcoin/Litecoin full/archive nodes (UTXO set, mempool, pruning, peer policies) with high‑availability RPC and optimized disk I/O
Operate Ethereum execution clients (e.g., Geth, Nethermind, Erigon, Besu) and consensus clients (e.g., Prysm, Lighthouse, Teku, Nimbus); manage beacon/execution pairings, JWT secrets, and checkpoint sync
Implement observability and telemetry using Prometheus/Grafana, Splunk, and Datadog for metrics, logs, and distributed tracing
Own backup/restore/DR strategies: snapshots, archive retention, multi‑AZ and multi‑region failover
Ensure hardfork readiness: plan and execute client upgrades, compatibility testing, and rollback strategies
Monitor and mitigate chain reorganizations (reorgs): implement alerts, RPC consistency checks, and failover strategies for deep reorg scenarios
Lead incident response, post‑mortems, and resilience testing; drive SRE practices and continuous improvement
Stay current with node software packaging and releases: track upstream client updates, security patches, and dependency changes
Implement zero-downtime deployment strategies for node upgrades using rolling updates, canary releases, and Kubernetes best practices
