About me
I’m Fengning Rao, a software engineering graduate with 16 years of experience across internet products and engineering.
I connect product planning with engineering delivery, taking work from business insight and positioning through information architecture, launch and iteration.
My experience spans content communities, vertical SaaS, local services and consumer products. I build from zero to one, then use data, agile systems and AI tools to help teams deliver with more focus.

Ways of working
📋 Product approach
I start with business goals and user problems, then move through discovery, positioning, architecture, prototypes and PRDs before closing the loop with data and iteration.
⚡ Delivery system

- Cloud-based delivery tracking with clear goals, scope, risks and acceptance criteria
- OKRs align the direction; RICE helps prioritize the work
🤖 AI collaboration
- Trae, Codex and WorkBuddy for prototypes, PRDs, decomposition and test cases
- Front-end pages, back-end APIs and integration work to reduce cross-role friction
- Team conventions for AI tools, code review and quality control
📈 Outcome focus
I track behavior, conversion, retention and interaction data, using A/B tests and operating analysis to locate problems and make product decisions measurable.
