DevOps & Blockchain
Infrastructure Engineer
I build, deploy, monitor, and troubleshoot reliable Linux infrastructure and blockchain nodes.
About Me
I'm an infrastructure-focused engineer working across DevOps and blockchain infrastructure. My work focuses on Linux systems, containerized workloads, blockchain node operations, monitoring, networking, and infrastructure troubleshooting.
I enjoy building reproducible infrastructure, documenting deployments, monitoring services, and solving operational problems across VPS and cloud environments.
Rather than treating servers as ephemeral black boxes, I take a disciplined systems engineering approach: ensuring secure host baselines, deterministic container setups, persistent storage on high-speed NVMe, and comprehensive observability pipelines that pinpoint degradations before services fail.
Zero guesswork configs using Docker Compose, modular systemd units, and codified parameters.
Safe handling of blockchain databases, snapshots, persistent volumes, and partition limits.
UFW firewall rules, isolated RPC loopback binding, and stable peer discovery routing.
Clear step-by-step guides so any operational recovery can be reliably re-executed.
