I help teams run production systems that stay online, whether they live in the cloud, on Kubernetes, or on bare-metal servers handling massive state and data. I’m a Senior Site Reliability / DevOps Engineer with 8+ years of hands-on experience operating infrastructure across AWS, GCP, Azure, DigitalOcean, and bare-metal environments. My work goes far beyond deployments — I design, operate, and recover systems where downtime, data corruption, or slashing are real risks. What I do in practice • Operate bare-metal servers (disk layout, RAID, IO tuning, recovery) • Run blockchain validator / RPC / full / archive nodes in production • Design safe Kubernetes architectures (StatefulSets, leader election, autoscaling trade-offs) • Keep large PostgreSQL systems stable under heavy load • Build monitoring that detects real failures, not just “pod is up” • Automate ops workflows using Go and Python Blockchain & validator experience I run and maintain validator node services, where reliability and correctness matter more than raw throughput: Validator and RPC node setup and maintenance Safe handling of upgrades, restarts, and snapshots Monitoring block height, peer health, syncing state, and reorgs Avoiding data corruption and slashing risks Designing leader-based consumption where horizontal scaling is unsafe This includes both cloud-based and bare-metal deployments, depending on performance and cost requirements.
