# Yu WenHao (余文皓) > I help companies turn AI from a chat tool into a working system. AI workflow consultant and independent developer. 14 years away from engineering, I used AI to build complete SaaS products independently. I write about AI-powered development, productivity systems, and solo entrepreneurship. ## About - Site: https://yu-wenhao.com - Email: mail@yu-wenhao.com - LinkedIn: https://www.linkedin.com/in/hence/ - Languages: Traditional Chinese (zh-TW, default), English (en) ## What I Do I'm an AI workflow consultant and independent developer based in Taiwan. After 14 years away from coding (working as PM, doing project management and data analysis), I discovered Claude Code in mid-2025 and built a SaaS product independently in 6 months. I hold an MDA degree from Minerva University and combine 15 years of hands-on experience with AI tools. Today I help companies adopt AI where it actually matters: turning repetitive daily work — email, calendars, document comparison, report generation — into workflows AI can run. Core belief: In the AI era, individuals can create more. ## Services - [AI Consulting & Workshops](https://yu-wenhao.com/zh-TW/services/): Enterprise AI adoption consulting, AI Coding corporate training, and one-day hands-on workshops (page in Traditional Chinese) ## Products - [AI Resume Advisor](https://yu-wenhao.com/zh-TW/products/ai-resume-advisor/): Resume diagnostic and optimization tool - [NeatToolkit](https://yu-wenhao.com/zh-TW/products/neatoolkit/): Free online tools (background removal, video compression, YouTube subtitle download) - [LinkedIn Resume Checker](https://yu-wenhao.com/zh-TW/products/linkedin-resume-checker/): Chrome extension for LinkedIn job matching ## Blog Categories - **Building Products**: No-Code, AI tools, from idea to launch - **Productivity**: Knowledge management, workflows, systems thinking - **Life & Learning**: Book reviews, values, long-term thinking ## Key Articles (English) - [2:30 A.M., Nobody at the Keyboard: Loop Engineering From One Desk](https://yu-wenhao.com/en/blog/loop-engineering/): How one person running a business on Claude Code steps back while the system works overnight - [The Complete Guide to Agentic Coding](https://yu-wenhao.com/en/blog/agentic-coding-guide/): From Vibe Coding to Autonomous Development - [Agentic Coding: One Year from Vibes to Agentic Engineering](https://yu-wenhao.com/en/blog/agentic-coding/) - [The AI Arbitrage Opportunity: Code Just Got Cheap](https://yu-wenhao.com/en/blog/ai-coding-arbitrage/) - [14 Years Away From Code.
