Great Systems.
Greater Integrity.
We design, integrate, and deploy enterprise-grade computer systems that power modern business. From architecture to implementation, Great Zheng delivers technical excellence with unwavering reliability.
Building the Systems That Build Tomorrow
Great Zheng is the operating brand of Heze Weizheng Network Technology Co., Ltd., a computer systems design firm headquartered in Heze, Shandong Province, China. Since our founding, we have been dedicated to one mission: designing and implementing integrated computer systems that give organizations the technical foundation they need to thrive in an increasingly digital world.
Our team brings together systems architects, software engineers, infrastructure specialists, and security professionals who share a commitment to precision, reliability, and long-term value. We do not believe in one-size-fits-all solutions. Every system we design is built around the unique requirements, constraints, and goals of the client it serves. That is what Great Systems means to us — and Greater Integrity is the standard we hold ourselves to in every engagement.
Whether we are designing a cloud-native infrastructure from scratch, integrating legacy platforms with modern services, or architecting a comprehensive cybersecurity posture, we bring the same rigorous methodology and deep technical expertise. Our clients span industries, continents, and scales — from agile startups to established enterprises — but they all share one thing in common: they trust Great Zheng to deliver systems that work, every time.
Comprehensive Systems Design & Integration
Six core service areas, each delivered with the depth and rigor that enterprise environments demand.
Computer Systems Design
End-to-end architecture and design of custom computer systems tailored to your operational requirements. We analyze your workflows, performance needs, scalability targets, and budget to create systems that align precisely with your business objectives. Every design includes detailed specifications, component selection rationale, and a clear implementation roadmap.
Computer Integrated Systems
Design and implementation of tightly integrated computing environments where hardware, software, networking, and data platforms function as a unified whole. We specialize in connecting disparate subsystems into cohesive architectures that eliminate redundancy, reduce latency, and simplify management across your entire technology stack.
Cloud Architecture & Migration
Strategic cloud infrastructure design covering public, private, and hybrid deployment models. Our cloud architects assess your existing environment, design the target architecture, and execute migrations with minimal disruption. We optimize for cost, performance, resilience, and compliance, with expertise across AWS, Azure, Google Cloud, and Alibaba Cloud.
Cybersecurity Architecture
Security by design, not as an afterthought. We architect defense-in-depth strategies encompassing network security, identity and access management, data protection, threat detection, and incident response planning. Our security designs align with NIST, ISO 27001, and industry-specific compliance frameworks to protect your most critical assets.
Systems Integration
Connecting your existing systems, platforms, and data sources into a seamless operational fabric. We handle API design, middleware configuration, data pipeline engineering, and legacy system modernization. The result is an interoperable ecosystem where information flows freely and processes run without friction across every department and function.

How We Deliver Great Systems
A proven four-phase methodology that ensures every engagement is predictable, transparent, and successful.
Discover
We begin by immersing ourselves in your business. Our team conducts stakeholder interviews, technical assessments, workflow analysis, and requirements gathering. We map your current state architecture, identify pain points, and define success criteria. This phase produces a comprehensive discovery document that becomes the foundation for everything that follows.
Design
Armed with a deep understanding of your needs, our architects design the target system. We produce detailed architecture diagrams, component specifications, integration schemas, security models, and implementation plans. You receive a complete design package that is reviewed, iterated, and approved before a single line of code is written or a single server is provisioned.
Deploy
Our engineering team brings the design to life. We build, configure, integrate, and test every component in a controlled environment before production rollout. Deployment follows a structured pipeline with automated testing, staging validation, and rollback capabilities. We manage the cutover with precision to minimize downtime and operational impact.
Support
Post-deployment, we provide ongoing monitoring, performance optimization, and technical support. Our team remains engaged to ensure the system performs as designed, to address any issues that arise, and to help you evolve the architecture as your business grows. We measure success not at launch, but through sustained operational excellence over time.

What Sets Us Apart
In a crowded market of technology service providers, here is why leading organizations choose Great Zheng.
Integrity-First Engineering
We recommend what is right for your business, not what pads our billables. Every architectural decision is justified with data, every trade-off is transparently communicated, and every deliverable is held to a standard we would accept for our own systems.
Deep Technical Mastery
Our architects and engineers are not generalists pretending to be specialists. Each team member brings deep domain expertise in their area — cloud infrastructure, security, data engineering, or systems integration — ensuring you get true subject-matter depth on every engagement.
Rigorous Methodology
We do not wing it. Our four-phase process — Discover, Design, Deploy, Support — is backed by documented standards, checklists, review gates, and quality assurance practices that have been refined across more than 150 successful project deliveries.
Global Perspective, Local Presence
Headquartered in Shandong, China, with clients across multiple continents, we combine the technical sophistication of a global firm with the accessibility and accountability of a dedicated local partner. Our team works across time zones to keep your projects moving.
Security by Design
Security is not a checkbox at the end of a project — it is a first-class design constraint from day one. Our security architects work alongside systems designers to ensure every component, connection, and data flow is protected by design, not patched after the fact.
Long-Term Partnership
We measure our success by the longevity of our client relationships, not by quarterly revenue targets. Many of our clients have been with us for years because we treat every engagement as the beginning of an ongoing partnership built on trust, results, and continuous improvement.
Let's Build Something Great Together
Whether you have a defined project, an emerging requirement, or simply want to explore how better systems design can transform your business, we would love to hear from you.
