CARBON × SILICON · AI-NATIVE ENGINEERING

Carbon knows the business.
Silicon builds the future.

Tangui Qitian — software built close to real-world use: understand the front-line workflow first, then write stable, usable systems through human–AI co-development. Mini Programs, admin consoles, ERP, SaaS and AI integration — this site gathers the focus areas and project practice.

01 / Focus Areas

From a single Mini Program
to a complete digital system

Areas of focus: turning real-world workflows into software that is stable, easy to use and built to evolve — every system with hooks ready for AI.

/01

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.

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.

02 / How It Works

Understand the context,
then write the code.

Inspired by the FDE (Forward Deployed Engineer) idea: rather than guessing from documents, get close to where the software is really used, understand the front-line workflow, and judge the code by how well it works in practice.

GoalTick off a feature listA system that truly works

How it’s builtHeadcount aloneHumans + AI, working together
DocumentationOften missingSource, docs and comments complete
STEP 01 · Observe

Get close to real use

Watch front-line work and map the real workflow and pain points — not just the requirements document.

STEP 02 · Define

Get the problem right first

Flowcharts, prototypes and a technical plan with clear scope, milestones and acceptance criteria — every item traceable.

STEP 03 · AI-ASSISTED BUILD

Human–AI pairing, rapid iteration

AI takes part in coding, testing and documentation while engineers own architecture and quality. A working build is demoed every week.

STEP 04 · Validate

Deploy, trial, refine

Deploy to a real environment for trial use, fix quickly based on real feedback, and make sure the system actually gets used.

STEP 05 · CONTINUOUS EVOLUTION

Documented, always evolving

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

03 / AI-Driven Dev

Carbon × Silicon
Co-Development

The Chinese name pairs carbon with silicon — and that is exactly the way of working here. People, the carbon, understand, judge and create; AI, the silicon, generates, verifies and accelerates. Together, development is faster and quality steadier.

● Carbon · Engineers

  • Context insight and judging needs
  • Architecture & technical decisions
  • Code review & quality control
  • Technical discussion and launch validation

● Silicon · AI

  • Code generation & refactoring
  • Automated test cases
  • API docs & code comments
