About me
Jiyu Yan · UK-based software engineer
Hi, I’m Jiyu.
I’m proud to run a one-person business. When you get in touch, you’re talking to the person who will do the work. I build websites and business software, from the first rough idea through to launch and handover.
Background
A little about my background.
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.
I have 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.
I’m excited by what people can build for themselves in this AI age. Try an idea, make a small tool, or put your business online. You don’t need to have everything figured out to start. If you hit a limit, want someone to check your approach, or need help turning a prototype into something dependable, I’d be happy to help.
