Engineering the Systems That Power Modern Enterprise
HillStop delivers end-to-end computer systems design, integration, and technical consulting for organizations navigating complex digital transformation.
Capability Matrix
Our multidisciplinary engineering team spans the full stack of systems design, from bare-metal infrastructure to application-layer architecture.
Distributed Systems Architecture
Design and implementation of fault-tolerant, horizontally scalable systems. We specialize in microservices decomposition, event-driven architectures, CQRS patterns, and service mesh orchestration for high-throughput environments. Every architecture we produce includes full observability instrumentation and failure mode analysis.
Cloud Infrastructure Engineering
Multi-cloud and hybrid-cloud infrastructure design with infrastructure-as-code at its core. Our teams work across AWS, Azure, and GCP to build resilient, cost-optimized environments. We handle network topology, IAM governance, container orchestration, and automated CI/CD pipelines that ship safely to production multiple times per day.
Data Platform Engineering
Design and build of data ingestion pipelines, lakehouse architectures, and real-time stream processing systems. We implement data mesh patterns, govern data quality at scale, and deploy feature stores that bridge the gap between raw data and production machine learning models.
Security Architecture
Zero-trust network design, identity fabric implementation, secrets management, and compliance automation. We build security into the platform layer so application teams inherit secure defaults. Our security reviews include threat modeling, penetration testing, and supply chain risk assessment.
DevOps Transformation
Platform engineering that equips development teams with self-service infrastructure, golden paths, and internal developer portals. We measure DORA metrics, optimize deployment frequency, and reduce mean time to recovery through systematic observability and incident response automation.
Legacy Modernization
Systematic decomposition of monolithic legacy systems into modern distributed architectures. We apply the Strangler Fig pattern, domain-driven design, and incremental migration strategies that preserve business continuity while retiring technical debt. Every modernization engagement includes knowledge transfer and operational runbooks for your team.
Technical Advisory
Architecture review boards, technology selection frameworks, build-vs-buy analysis, and engineering org design. We help leadership teams make informed decisions about technical strategy, vendor selection, and organizational structure to sustain long-term engineering velocity.
Our Engineering Pipeline
Every engagement follows a disciplined systems engineering methodology refined across hundreds of successful deliveries.
Discovery
Stakeholder interviews, current-state architecture assessment, constraints mapping, and success criteria definition.
Design
Architecture decision records, system context diagrams, data flow models, and iterative design reviews with your engineering team.
Prototype
Working proof-of-concept deployed to a sandbox environment. We validate architectural assumptions before committing to full-scale implementation.
Build
Infrastructure provisioning, CI/CD pipeline construction, incremental feature delivery with continuous integration and automated testing.
Operate
Production cutover, monitoring dashboards, runbooks, on-call handoff, and post-launch optimization sprints to tune performance and cost.
Solutions Portfolio
Representative engagements that demonstrate our approach to complex systems challenges across industries.
Financial Trading Platform Re-architecture
Redesigned a mid-frequency trading platform serving 12 global markets. Migrated from a monolithic on-premise deployment to a cloud-native event-sourced architecture on AWS, achieving p99 latency under 800 microseconds and eliminating single points of failure across the order management pipeline.
- Event-driven microservices with Kafka Streams
- Multi-region active-active deployment
- Real-time risk calculation engine
- CHAOS engineering validated failover under 2 seconds
Healthcare Interoperability Platform
Designed and delivered an HL7 FHIR-based interoperability layer connecting 47 hospital systems across three health networks. The platform normalizes patient data, lab results, and clinical workflows into a unified API consumed by electronic health record systems and patient-facing applications.
- FHIR R4-compliant API gateway
- HIPAA-compliant data pipeline with audit logging
- 47 legacy system adapters built in 6 months
- Synthetic data generation for compliance testing
Supply Chain Digital Twin
Built a real-time digital twin of a global manufacturing supply chain spanning 18 factories and 230 distribution centers. The platform ingests IoT sensor data, ERP transactions, and logistics feeds to power predictive inventory optimization and disruption scenario modeling.
- Apache Flink stream processing at 2M events/sec
- Graph-based supply network model in Neo4j
- What-if simulation engine with 15-minute refresh
- Reduced stockouts by 34 percent in first quarter
E-Commerce Platform Cloud-Native Rebuild
Led the migration of a top-50 e-commerce platform from colocated hardware to GCP. Redesigned the checkout flow for idempotency, built a CQRS inventory system, and implemented gradual traffic shifting that maintained zero-downtime throughout the 8-month migration window.
- Kubernetes-based deployment with auto-scaling
- Event sourcing for order management
- Blue-green deployment with automated rollback
- Cost reduction of 41 percent versus colocation
