What I Built Stays with Me
I spent two and a half years trying to compensate for a late start in tech. But what truly carried me was the eight years I spent in a classroom before that.
Toshiki Notes
Supporting people through systems.
Building foundations that move teams and products forward.
I transitioned from education to software engineering. I enjoy deepening my technical skills, but I'm equally drawn to thinking about how technology serves organizations and operations in practice.
Designing foundations, building systems, defining how things run, turning ambiguity into forward motion. This kind of work — quiet but essential — is what I've found rewarding in both the classroom and in engineering. I'm still early in my career, so I'm writing to capture what I'm learning along the way.

Why I Write in Public
Writing in public forces clarity, builds trust over time, and creates unexpected connections. Here is why I keep doing it.
Topics
Infrastructure
Architecture, access control, cost optimization, audit logging. Building foundations that hold as the product grows.
Career
Connecting technology and business through career decisions. Recording the thinking behind the choices.
SRE / Platform
Reliability and developer experience. The area I most want to deepen.
Writing in Public
Publishing the process, not just the result. I believe there's value in sharing what you learn along the way.
