Capabilities
Application Programming Interface (API)
We design and implement secure, scalable Application Programming Interface (API) solutions that enable systems, applications, and data platforms to communicate seamlessly. Our approach emphasizes interoperability, performance, and governance, supporting modern cloud and hybrid environments while enabling rapid integration and reuse across programs and partners.
APIs are mission infrastructure, interconnecting applications within and across federal agencies and automating operations so government can focus on the strategic decisions that protect national interests and accelerate civilian services.
Secure & Governed Integration
We design APIs with enterprise-grade security, access control, and governance to ensure trusted system-to-system communication and compliance with organizational and regulatory requirements. Our APIs are built on FedRAMP-authorized platforms, aligned to Federal Information Security Management Act (FISMA) security controls, and HIPAA-compliant for protected health data, a pattern we apply consistently across all programs under our federal health partners.
Cloud-Native & Scalable Architecture
Our cloud-native API architectures support high availability, performance, and elastic scaling, enabling reliable integration across cloud, hybrid, and on-premise environments. We’ve migrated legacy on-premise applications to AWS cloud-native solutions, and our teams extend this expertise across Azure and other cloud environments for our federal partners.
Reuse, Automation & Modernization
APIs enable modular, reusable services that accelerate application development, automation, and modernization while reducing integration time and technical debt. We modernized a legacy SAS-based analytics platform to a Databricks solution, with APIs serving as the integration layer that enabled the transition without disrupting downstream systems and users.
Customer Stories
eSimplicity engineers developed System Analytics for Governance & Efficiency to provide centralized visibility into Databricks compute usage and cost across a large-scale federal health data environment.
eSimplicity proudly supported the NIWAWS by creating a Terminal Defense training scenario leveraging lessons learned from recent real-world operations.
eSimplicity re-engineered how the platform handled concurrent requests and database interactions, aligning application-level behavior with real user demand, dramatically increasing per-container throughput while preserving reliability and standards-based API access.
