About ZhengKa
A technical consulting and system integration partner for small and mid-sized projects.
We turn scattered devices, software, networks, and workflows into one maintainable system.
Capability Structure
We reduce the system gaps nobody can clearly explain.
System Integration and Interfaces
We map the boundaries between interfaces, terminals, admin panels, and third-party services so interactions stay testable and traceable.
Network and Remote Maintenance
Office and device networks, VPNs, port policies, and remote maintenance links.
Security and Continuous Maintenance
Account permissions, data backup, website protection, log retention, and emergency recovery.
How we work together
As a one-off, a project, or a standing arrangement.
One-off
Fault isolation, a configuration change or a design review — a single piece of work that ends when it is done.
Project delivery
A scoped project with clear acceptance points, from reviewing the current state through to handover documentation.
Ongoing maintenance
Inspections, change management and fault response on a recurring schedule, with one fixed place to raise issues.
Working Principles
A solution must be understandable, maintainable, and reviewable by the field team.
Define Boundaries First
Decide whether a problem belongs to the business system, the device, the network, or the operating procedure.
Keep Maintenance Paths
Plan accounts, logs, backups, remote support, and troubleshooting paths during deployment.
Make Delivery Verifiable
Every interface, device, page, and download needs a clear test method, not a verbal confirmation.
Get Started
Share your current situation first.
A question, a fault or a whole project — any of them is a place to start.
