About

Hi I am Toby.

I write Go, build backend systems, and obsess over reliability. This blog is a dump of what I’m learning or breaking — from email infrastructure and testing to containers and distributed systems.

I like reliable systems, clean code, and figuring things out the hard way. I treat this blog as a working notebook, not a portfolio — thinking in public, mistakes and all. Lately, I’ve been diving and learning about email protocols (SPF, DKIM, DMARC), building tooling under Apprentice Systems, and exploring how real-world systems hold together.

I believe in understanding what I use, contributing back, and building tools I wish existed.

This isn’t a showcase. It’s a dev log — full of trials, errors, and the occasional insight.

🛠 Tools I Use

• Languages: Go (testing, pprof, race detector, fuzzing)
• Infra: Docker, Linux,
• DevOps / CI: Git, GitHub Actions, Bash, Makefiles, systemd, crontab
• Debugging: netstat, tcpdump, Wireshark, journalctl
• Workflow: GoLand + IdeaVim, macOS M2 Max, Obsidian
