Intro
I’m an infrastructure and reliability engineer based in Japan. Over the past decade, my work has centered on mission-critical environments where resilience isn't optional—scaling high-throughput mail delivery platforms, distributed observability, and enterprise server architectures.
This site is an extension of my homelab—a place where I document cloud infrastructure automation with Terraform, architectural notes, and deep-dive technical write-ups. I take a practical, hands-on approach: understanding how systems work under the hood, cutting through unnecessary complexity, and building setups that hold up under real production pressure.
Notes from the homelab: engineering deep-dives, infrastructure setups, and lessons learned along the way. View all articles
Last year I failed to shoehorn Umami Analytics into AWS Aurora DSQL. Here is the simpler, near-$0 architecture conceptualized for HOME-LAB.net: serverless Lambda + S3 edge ingestion paired with an outbound pull into local PostgreSQL on ZFS.
How to self-host private email without port forwarding, dynamic IP blacklists, or reboot bounces—combining Amazon SES, an encrypted S3 relay bucket, Stalwart, and Roundcube.
Why keeping cold spares, temperamental memory, and decommissioned enterprise switches is an operational trap—and the brutal solar and battery reality check of continuous idle rack draw.
I'm an infrastructure engineer who can't draw a straight line. Here's how a dozen rounds of 'nope, try again' with an AI design assistant turned into a logo I actually love for my homelab.
What happens when an infrastructure engineer plans a garden upgrade in Japan—treating spigots like availability zones, over-provisioning 220V corner power for Christmas lights, lecturing garden valves about Zigbee physics, and replacing weeding toil with groundcover.
Why seriesoftub.es—an open-source browser game where you build an ISP from a single router to a transit-free Tier 1 carrier—is one of the most deceptively challenging networking simulations on the web.
Cloud marketing promises infrastructure in seconds, yet a greenfield multi-region Terraform apply still leaves you staring at a spinner for half an hour. Here is what is actually happening inside the AWS control plane while you wait.
