Contact and enquiry information
The enquiry form prepares a draft using your email app. It does not automatically submit your form details to a website database. You choose whether to send the message. Email and WhatsApp links open those services, which handle information under their own policies.
Jianyu uses information you send to assess and respond to the enquiry and discuss a potential engagement. For questions about your enquiry information, contact oliverdongjiaao@gmail.com.
Website delivery
This site is hosted on Vercel. The hosting provider may process technical request information needed to operate and secure the website. No advertising trackers have been added to this website.
Public case materials
Analytical case studies are anonymised and analytically reconstructed. Development examples distinguish interested replies and quotation requests from sales. Case-specific assumptions and limitations appear with each example.
Service information
Website content is general information about the practice. The agreed proposal or engagement document defines the actual scope, deliverables, acceptance standards, fees and timing. Public content does not constitute an investment recommendation, legal, tax or technical opinion.
