About me

Jiyu Yan · UK-based software engineer

I turn unclear business problems into useful software.

I work directly with small businesses and teams—from the first conversation and solution design through to coding, launch, and handover.

Background

Engineering depth, without the agency layers.

I have more than six years of experience across engineering, implementation, and product delivery. My work includes backend development, API integrations, JavaScript business logic, reporting, SQL and database work, internal automation, and technical solution design.

At UL Solutions, I delivered more than ten long-term enterprise implementation projects, often taking ownership from discovery and requirements through solution design, coding, configuration, and go-live.

I hold an MSc in Computer Science with distinction from the University of Warwick. That technical background matters, but the goal stays simple: understand the real problem, build only what is useful, and leave the work clear enough to maintain.
