About

I am Armstrong Yan, a backend and platform engineer based in Singapore.

My work focuses on reliable backend systems, platform engineering, distributed services, and practical automation. I care about systems that remain understandable under pressure: clear interfaces, observable behavior, safe failure handling, and engineering workflows that help teams move faster without losing the ability to reason about the software.

This site is where I write public notes on backend architecture, cloud infrastructure, event-driven systems, AI-assisted software engineering, remote agent workflows, and personal knowledge systems. A recurring theme is the boundary between human judgment and automation: how repositories, feedback loops, and operating practices make complex work easier to recover, verify, and improve.

Outside engineering, I am drawn to things with patience, movement, and vitality: table tennis, cycling, cooking, music, and the quiet discipline of continuing anyway.
