Hello, I'm

Satoru.

DevOps / SRE · Node Infrastructure · Indonesia

I keep validator fleets alive. As the DevOps behind AuraNode, HexaNode, TropicalCrypto, SinceDAO, and Rektanalisis DAO, I automate node operations, monitoring, and incident response so the networks I run never blink.

about me

I make infrastructure boring, on purpose.

My job is uptime. I treat validators like production systems that can never go down: everything is codified, observed, and rehearsed before it ever ships to mainnet. If a node fails at 3am, the automation should recover before anyone wakes up.

I care about the unglamorous parts most people skip: key custody, graceful upgrades, backpressure, and honest post mortems. Reliable networks are built there, not in the demo.

experience

Where I've been.

2024 — Present

Lead DevOps · AuraNode & HexaNode

Own the validator infrastructure end to end: provisioning, upgrades, monitoring, and on call. Built the automation that lets a small team run a growing fleet without heroics.

2023 — Present

Infrastructure Engineer · TropicalCrypto, SinceDAO, Rektanalisis DAO

Design deployment pipelines and observability for multiple networks. Standardized how nodes are shipped so every DAO runs the same tested, reproducible stack.

2021 — 2023

Systems Administrator · Cloud & Bare Metal

Ran mixed cloud and bare metal environments, learned the hard way why backups, runbooks, and boring deploys matter more than clever ones.

Things I keep running.

automation

One command validator

A Terraform and Ansible pipeline that brings a hardened validator from bare host to synced and signing in one run, keys sealed and monitoring wired.

observability

Fleet watchtower

A Prometheus and Grafana mesh across every network I operate, with alerting tuned so pages mean something and dashboards tell the truth at a glance.

resilience

Zero downtime upgrades

A rehearsed upgrade flow with automated failover between redundant signers, so protocol upgrades ship without missing a block.

chaos

Game day drills

Scheduled failure injection against staging fleets to prove the recovery automation actually works before mainnet ever needs it.
