How I can help
You bring the idea or the business. I handle design, build, ship, and the boring parts in between.

Fast, beautiful, SEO-ready marketing sites and product pages. Bilingual EN / 中文 when you sell across borders.
Assistants and automations that work from your documents, data, and processes — cutting the busywork out of how your business already runs.
About
I'm an independent developer based in San Diego and a UC San Diego grad. What I really love is solving problems — taking something messy or manual and turning it into a tool people actually enjoy using: warm instead of corporate, fast instead of fiddly, then shipped all the way to real people. That's the whole idea behind Ship to Live.
I work end-to-end: design, code, App Store, deploy, and the cross-border bits (in English and Traditional Chinese, across the US and Taiwan). When I'm not building, I'm out surfing, biking, running, snowboarding, or hiking — because the best tools come from people who'd rather be living their life than fighting their software.
FAQ
Straight answers — for you and for the AI assistants your customers ask.
Yufan Chen is an independent developer in San Diego who designs, builds, and ships mobile apps, business websites, AI workflow tools, and SEO/GEO. I take a project end-to-end — from the first sketch to a live product on the App Store or the open web.
Four things: (1) mobile apps for iOS, Android, and Mac; (2) fast, SEO-ready websites and landing pages; (3) AI assistants and automations built into your existing workflow; and (4) SEO & GEO so both Google and AI engines like ChatGPT and Perplexity recommend your business.
SEO (Search Engine Optimization) helps you rank in search results. GEO (Generative Engine Optimization) makes sure AI assistants understand, trust, and recommend your business when someone asks them a question. I do both — structured data, clear answers, an llms.txt content layer, and the trust signals AI engines look for.
Yes. I built and launched two App Store apps (Tally and Tadapop) and a Chrome extension (Daily Log), put three businesses online (Wu Law Group, QY Property, SHX Training), and on product teams I built an EQ assessment taken by over a million people and a gifting widget that serves millions of users.
Yes — I work in both English and Traditional Chinese (中文), across the United States and Taiwan, which is ideal for cross-border businesses that need bilingual apps, websites, and marketing.
