The mind of carbon · The might of silicon

Carbon at heart.
Silicon in hand.
Wisdom, awakened.

Tangui Qitian. Needs understood up close, in their real context; software built by humans and AI together — Mini Programs, admin consoles, ERP, SaaS and AI integration. This site gathers the focus areas and project practice.

I · What We Do

Nine areas of focus, one craft

From a single Mini Program to a complete management system, each is designed around the true shape of its context — with room left for AI to grow.

First

WeChat Mini Programs

Consumer- and store-facing Mini Programs for commerce, booking, membership, marketing and service — integrated with WeChat Pay, Official Accounts and WeCom on one shared data layer.

WeChat PayMembership & MarketingSubscription MessagesCloud Dev
Second

Admin Consoles

A unified operations back office: org structure, role- and data-level permissions, approval workflows, report exports and audit trails for smooth cross-team work.

RBACData PermissionsBPM EngineAudit Logs
Third

ERP Systems

Inventory, procurement, production and finance built around your real processes — multi-entity and multi-ledger, with operations and finance integrated and data traceable end to end.

Fourth

CRM Systems

End-to-end data modelling from lead and opportunity to collection, a 360° view of every contact, and a clear sales pipeline.

Leads & Opportunities360° ViewSales PipelineCollections
Fifth

MES Systems

Connect planning to the shop floor: work orders and dispatching, operation reporting, quality inspection and equipment management, with MRP and full batch traceability.

Sixth

WMS Systems

Receiving, put-away, picking, shipping and cycle counts made digital, with bin-level location control and barcode / PDA operations for accurate real-time stock.

Seventh

BI Dashboards

ERP, CRM, MES and other sources brought together in a unified metrics system and data platform, with self-service analysis and real-time big-screen dashboards to support decisions.

Eighth

SaaS Platforms

Multi-tenant architecture, subscription billing and open APIs, in both SaaS and on-premises forms — distilling domain experience into a reusable product architecture.

Ninth · The Finishing Stroke

AI Integration

Large models embedded in existing systems: RAG-based knowledge bases, intelligent Q&A, automated document and data processing and AI Agent workflows — private model deployment supported.

II · Method

Hands-on, knowing by doing

FDE
as inspiration

Inspired by the FDE (Forward Deployed Engineer) idea: not watching from afar, but getting close to the real context, reading the front line, and judging code by its results.

Step
in
I

Immerse 入场

Get close to the real context, watch front-line work, map workflows and pain points — and see what the documents leave out.

II

Co-design 共谋

Draw up flowcharts, prototypes and a technical plan, with clear scope, milestones and acceptance criteria.

III

Build with AI 共筑

Humans and AI build side by side, with a working version shown every week — refining as we go, never straying from the path.

IV

Launch 落地

Deploy, trial in real use, fix fast — until the system is truly in use.

V

Document DOCUMENT

Source code, documentation and runbooks kept complete; continuous iteration, with AI capabilities added step by step.

The usual way
  • Needs understood second-hand, from documents
  • Ends at a feature checklist
  • Reports progress by milestone
  • Builds by adding headcount
The Tangui Qitian way
  • Observe the real context directly
  • Done when it truly works
  • A working version, visible every week
  • Humans and AI build together
III · Carbon & Silicon

Carbon and silicon, creating as one

Carbon is the foundation of life — human insight, experience and judgment. Silicon is the foundation of the chip — AI’s computing power, memory and speed. Our Chinese name joins the two, and so does our craft: humans and AI work as a pair, each bringing its strengths, each checking the other.

Carbon · Human

CARBON · HUMAN
  • Read the context, clarify needs
  • Design the architecture, make the calls
  • Review the code, guard the quality
  • Technical discussion, launch validation

Silicon · Intelligence

SILICON · AI
  • Generate code, refactor and refine
  • Write tests, verify automatically
  • Draft documentation, tidy comments
  • Process data, assist analysis
Humans excel at thought, machines at speed; where the two meet, mastery follows.
IV · Practice
