NodeOps Engineer

End-to-End Node Architecture: Engineered, deployed, and scaled production-grade blockchain infrastructure from scratch using Docker, Kubernetes StatefulSets, and Helm charts across major L1/L2 networks, including Ethereum, Optimism, Arbitrum, Sui, Hedera, Polkadot, and Tron. Hardfork & Upgrade Lifecycle Management: Successfully managed network-critical upgrades, protocol maintenance, and emergency coordination for complex hardforks across multi-chain ecosystems, ensuring zero-downtime ledger continuity. Advanced Client Optimization & Capacity Planning: Optimized high-throughput execution and consensus clients, including Erigon and Lighthouse, tuning memory allocation, peer discovery parameters, and NVMe disk I/O to maximize synchronization speeds and minimize block propagation latency. Infrastructure-as-Code for NodeOps: Fully automated blockchain node provisioning, snapshot restorations, and validator configurations using Terraform and Ansible, cutting node deployment and recovery time by over 80%. Data Availability & Snapshot Management: Designed automated backup and high-speed snapshot sync pipelines utilizing AWS S3/CloudFront and custom scripts, drastically accelerating data recovery times for archival and full nodes. Monitoring & Metric Synthesis: Deployed comprehensive Prometheus, Grafana, and Loki logging and monitoring frameworks to track blockchain-specific metrics (e.g., peer counts, block height lag, validator uptime, slashing risks). Incident Response & SRE Culture: Participated in a rigorous 24/7 on-call rotation, serving as incident commander for critical infrastructure anomalies and authoring blameless post-mortems to eliminate single points of failure and reducing recurring toil.
