About these cases, upfront

We don't publish inquiry counts, deal values or growth percentages — you can't verify those numbers, so quoting them would just be talking to ourselves. This page covers two things only: what we actually built, and how you can check it yourself. Cases without client consent are shown anonymously.

Bilingual website

HaiTu AI's own bilingual site

Verifiable now

Client

HaiTu AI itself (Haitusi Network Technology). The brand serves door & window manufacturers going overseas, so visitors include both Chinese factories and overseas buyers.

The problem

The previous site led with feature lists and had no English version for overseas visitors. Worse, the lead form showed a success message even when no backend was connected — the data was silently discarded.

What we did

Rebuilt the information architecture from a feature list into an export-growth funnel
Added a bilingual structure: Chinese keeps its original URLs, English lives under /en
Configured per-page bilingual SEO with canonical and reciprocal hreflang
Routed leads through a server endpoint to WeChat Work, carrying UTM and source page
Unified event tracking and added a mobile sticky CTA

What was delivered

15 pages in each language, all statically prerendered
Per-page title, description, keywords and OpenGraph
Sitemap with reciprocal Chinese/English hreflang
Leads forwarded server-side; no success message unless delivery is confirmed

How to verify

You are reading it. Switch languages with 中 / EN at the top right, and view source to check the hreflang tags and structured data.

Door & window AI system

Window factory · end-to-end management system

Anonymized

Client

A door & window factory in southern China (anonymized), running its own production lines across retail, project and OEM work.

The problem

Doors and windows are highly customized. Drawing, material calculation and quoting sat with different people, the workshop had many steps, and the numbers never reconciled — so real cost and margin stayed unclear.

What we did

Built a door & window CAD workbench covering mullion layouts, casement, sliding and folding, irregular shapes and corner units
Added AI drawing recognition for images and multi-page PDF drawings
Built an in-house formula engine that expands the bill of materials from the window type
Connected quote → order → purchasing → production scheduling → outbound end to end
Set up nine role permissions with amount redaction

What was delivered

CAD workbench with 3D preview and top view
DXF export at 1:1 in millimeters, opens directly in AutoCAD
Smart BOM, cutting optimization and shortage checks
Three quote print layouts plus drawing confirmation sheets
Eight-state order flow and production scheduling

How to verify

Book a demo and see it running. Open an exported DXF in your own AutoCAD to check the dimensions and scale.

This client has not authorized public disclosure. The background and problem describe what is typical for this kind of company; the real brand, details and screenshots follow once we have consent.

Export website

Export manufacturer · standalone overseas site

Anonymized

Client

An export-focused door & window manufacturer (anonymized), mainly aluminium and system windows.

The problem

Before deciding, overseas buyers want installed projects, product ranges, craftsmanship detail and technical drawings. Most export sites offer a handful of product photos, so inquiries stall at the first step.

What we did

Built a multilingual export site with product and project content
Structured the site and keyword coverage around export SEO
Designed the inquiry form and multi-channel conversion paths

What was delivered

Multilingual site live
Product and project content written
Inquiry form and conversion paths

How to verify

The site address, real screenshots and content details follow once the client authorizes disclosure.

WeChat Mini Program

Window brand · WeChat Mini Program

Anonymized

Client

A door & window brand selling through retail stores and dealers (anonymized).

The problem

Acquisition depended on stores and dealers with no online entry point, and customer records lived in salespeople's personal WeChat accounts.

What we did

Built product and project showcases in a Mini Program
Added online quoting and lead capture
Moved customer records into company ownership

What was delivered

Mini Program live
Product and case showcase modules
Lead capture and customer records

How to verify

The Mini Program name, real screenshots and feature details follow once the client authorizes disclosure.
