Corporate sites, mini programs and complex systems
built to a maintainable standard
One team from requirements to production. Source code, documentation and deployment are handed over — no lock-in, no hidden hooks.
Troubleshooting orders welcome: root cause first, quote after.
State the goal, get scope and quote back
Add me on WeChat with the business goal, current state and deadline. No group chat and no kickoff meeting before scope is clear.

Four service lines
Corporate websites
A front door that also gets indexed
Websites built to be maintained: clear structure, content you can edit yourself, and SEO that survives launch.
Read →Mini programs
A business entry point inside WeChat
Commerce, booking, membership, utility and game mini programs — from prototype to review and launch, integrated with your systems.
Read →Complex business systems
Back office, approvals and multi-role data scopes
ERP, OA, ticketing, inventory and collaboration systems built per business domain. The hard part is permissions, audit and staying changeable in three years — not page count.
Read →Troubleshooting and repair
Per order: root cause first, quote after
Production incidents, performance regressions, legacy rescue. I state the root cause and the repair path before talking price; if I cannot locate it, you do not pay.

Not faster — more durable
Speed is easy to promise and hard to verify. These three are checkable.
One engineering standard
Layering, contract consistency and deny-by-default authorization are enforced by the build, not by memory at review time.
Problems are traceable
End-to-end traceId and structured logs follow one request from entry to async task; sensitive actions are attributed to a person, time and IP.
One point of contact
Requirements, design, development and launch are handled by the same person. Fewer handovers, less distortion.
Five steps, each one verifiable
Discovery
We talk through business goals, current state and constraints on WeChat or phone. Free, and no contract pressure.
Scope and quote
Scope, timeline, milestones and acceptance criteria go into one list, priced as a fixed total. Scope changes are re-quoted, never added afterwards.
Prototype sign-off
You click through real pages and confirm structure and wording before development starts. Structural changes are cheapest here.
Milestone delivery
Working builds delivered per milestone and accepted by you at each one — no single big reveal at the end.
Launch and handover
Deployed into your environment with source, docs, deploy scripts and runbook. After handover you can hand it to anyone.
