Senior backend and platform engineer based in Singapore, with 10+ years of experience across distributed systems, production reliability, backend architecture, and platform engineering.

I focus on building systems that are scalable, observable, and practical to operate. My work often sits at the boundary between product backend systems and platform infrastructure: API design, asynchronous workflows, incident diagnosis, reliability improvements, and automation that reduces operational friction.

My current work remains anchored in backend and platform engineering, with a growing focus on AI-connected systems and engineering workflows. I am especially interested in how cloud infrastructure, automation, and AI-assisted tools can make complex systems easier to operate, debug, and evolve.
