Industry Verticals

ZHANGJIENING LLC operates from Salt Lake City, Utah, providing end-to-end computer systems design services. Our methodology prioritizes resilience, security, and future adaptability. Every architecture we produce is documented, tested, and designed to outlast the technology wave that inspired it.

Holistic Architecture

We design the full stack from network topology through application logic, ensuring every layer communicates efficiently.

Performance-First Engineering

Latency budgets, throughput modeling, and bottleneck analysis are core to every design deliverable we produce.

Compliance by Design

Regulatory requirements are embedded into architecture, not bolted on afterward. We design for SOC 2, HIPAA, and GDPR readiness.

Comprehensive Systems Design Services

From greenfield architecture to legacy modernization, our service catalog covers the entire systems lifecycle.

Systems Architecture Design

End-to-end architecture blueprints covering compute, storage, networking, and application layers. We produce detailed system models, data flow diagrams, and component interaction specifications that form the backbone of reliable software infrastructure.

Cloud Infrastructure Engineering

Multi-cloud and hybrid architecture design for AWS, Azure, and GCP environments. We specialize in container orchestration, serverless patterns, and infrastructure-as-code deployments that make systems reproducible and auditable.

Database & Data Systems

Schema design, query optimization, and data pipeline architecture for OLTP, OLAP, and real-time streaming workloads. We model data domains that balance normalization with query performance across relational and NoSQL engines.

Learn more →

Security Architecture

Zero-trust network design, identity and access management frameworks, encryption strategy, and threat modeling. Our security architecture integrates with development pipelines to shift security left without slowing delivery velocity.

Learn more →

API & Integration Design

RESTful and event-driven API architecture with versioning strategies, rate limiting, circuit breaking, and comprehensive documentation. We design integration layers that make heterogeneous systems communicate reliably.

Learn more →

Technical Advisory & Audit

Architecture reviews, system audits, and technical due diligence for investment, acquisition, or internal risk assessment. We deliver actionable findings ranked by severity and impact with remediation roadmaps.

How We Engineer Systems

A disciplined, repeatable methodology that turns requirements into production-grade systems on predictable timelines.

1

Discovery

Deep-dive requirements gathering, stakeholder interviews, and existing system analysis. We document current state and define measurable success criteria before drawing a single diagram.

2

Design

Architecture modeling with component diagrams, data schemas, API contracts, and deployment topologies. Every design decision is traced back to a documented requirement or constraint.

3

Validation

Peer review, threat modeling, failure mode analysis, and load simulation. We stress-test architectures on paper before a single line of infrastructure code is written.

4

Delivery

Detailed implementation specifications, IaC templates, CI/CD pipeline configurations, and comprehensive runbooks. Every deliverable includes operational documentation for the teams who will maintain it.
