Hello
I build SaaS products end to end—solid systems, clear UX, steady delivery.
Full-stack engineer focused on subscription software: shipping features customers rely on, improving reliability, and partnering with product and design to move metrics.
About
Engineer, product-minded, SaaS-focused

I'm Richard (Ziming) Qin, a full-stack software engineer who spends most of my time on SaaS—turning roadmap ideas into production code, tightening performance, and keeping releases predictable as the product grows.
I care about clear interfaces between services, pragmatic testing, and UX details that make complex workflows feel simple. I work best in teams that value direct communication, ownership, and iterating from real user feedback.
