AI in your workflow new

SEO · AEO · GEO
Get found — on Google and in AI answers.
"Search" isn't one box anymore. People still Google you, but they also read the AI answer at the top of the page and ask ChatGPT or Perplexity "who's the best [your business] for this?" — three different places, each optimized a different way. Here's what each one means and what I do about it.
Search Engine Optimization
Getting your link to appear in search results.
The classic blue links on Google & Bing.
Answer Engine Optimization
Getting your content pulled into answer boxes and quick AI replies.
Google featured snippets & AI Overviews.
Generative Engine Optimization
Getting cited inside detailed, AI-generated summaries.
ChatGPT, Perplexity & Gemini.
About
Hi, I'm Yufan.
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
Questions people ask before we start
Straight answers — for you and for the AI assistants your customers ask.
What does Yufan Chen do?
Yufan Chen is an independent developer in San Diego who designs, builds, and ships mobile apps, business websites, AI workflow tools, and SEO/AEO/GEO. I take a project end-to-end — from the first sketch to a live product on the App Store or the open web.
What can you build for my business?
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, AEO & GEO so Google, its AI answers, and AI engines like ChatGPT and Perplexity all recommend your business.
SEO, AEO, GEO — what's the difference?
They're three ways to get found, for three different places your customers look. SEO (Search Engine Optimization) gets your link to appear in Google's search results. AEO (Answer Engine Optimization) gets your content pulled into answer boxes and quick AI replies — Google's featured snippets and AI Overviews. GEO (Generative Engine Optimization) gets your business cited inside detailed AI-generated answers from ChatGPT, Perplexity, and Gemini. I do all three — fast, well-structured pages, clear answers, an llms.txt content layer, structured data, and the trust signals every engine looks for.
Have you shipped real products?
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.
Do you work in Chinese as well as English?
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.
Where are you based, and do you work remotely?
I'm based in San Diego, California, and I work with clients remotely across the US and Taiwan. The best way to start is the contact form below, or a message on LinkedIn.
