ROUND US LLC provides computer systems design and integration for organisations that need infrastructure that connects cleanly, operates reliably, and stays maintainable over time.
Enterprise architecture reviews, cloud-native design, microservice decomposition, hybrid and multi-cloud strategy, and disaster recovery planning. Every design includes decision records and trade-off analysis.
API development (REST, gRPC), event-driven architecture with Kafka and RabbitMQ, legacy system modernisation, data synchronisation, and ETL pipeline engineering. We choose the right pattern for each context.
Infrastructure-as-code with Terraform and OpenTofu, Kubernetes cluster engineering, CI/CD pipeline design, configuration management, and cloud cost optimisation. Manual operations become the exception.
Zero-trust architecture, IAM and identity federation, threat modelling, compliance automation (ISO 27001, SOC 2, CCPA), incident response planning, and managed platform operations with 24/7 monitoring.
ROUND US LLC is a computer systems design and integration firm based in Whittier, California, serving organisations across the United States.
Our name reflects our approach: we look at the whole picture rather than individual components. Systems integration is not about making each part perfect in isolation — it is about making everything work together as a coherent whole. That requires understanding not just the technology but the operational context, the team capabilities, and the business constraints that shape every decision.
Our practice spans architecture consulting, integration engineering, cloud infrastructure, security compliance, and managed platform operations. We focus on mid-market organisations that have outgrown their startup infrastructure but are not yet ready for a full enterprise platform team. Our clients come back because we deliver clear documentation, measurable outcomes, and infrastructure they can operate independently.
We have delivered over 170 systems across finance, healthcare, logistics, and technology sectors with a 95 percent client retention rate.
We represent no hardware or software vendor. Recommendations are based on technical and operational fit for your organisation, not on partner incentives or commission structures.
Decision records, runbooks, and network diagrams are produced as core deliverables. An engagement is not complete until your team can operate without our involvement.
Success criteria agreed before work begins. Performance benchmarks, uptime targets, and cost baselines are defined upfront and tracked continuously through delivery.
Headquartered in Whittier, we serve clients across the United States with local regulatory knowledge and engineering standards that apply anywhere.
Four connected phases adapted to each project's specific complexity and timeline.
Current-state mapping, stakeholder interviews, gap analysis, and prioritised recommendations with resource estimates.
Target architecture with multiple options, trade-off analysis, phased roadmap, risk register, and cost baselines.
Iterative build with continuous validation. Short cycles, rollback at every increment, documentation produced alongside code.
Runbooks, knowledge transfer sessions, and optional managed operations. Your team takes full ownership with our support.
Round Us redesigned our integration layer across four business units. The migration was seamless and the documentation they left is now our operational standard.
Their cloud migration work was meticulous. They moved over 40 services with zero incidents and reduced our monthly spend by 24 percent through FinOps optimisation.
We engaged them for a security architecture review. It was the most thorough we have commissioned — they identified gaps that three previous auditors had missed.
The Kubernetes platform engineering they delivered transformed our deployment reliability. We went from weekly incidents to 99.98 percent uptime in three months.
We schedule a no-obligation consultation within one business day.
