Two fine-tunes powering Momentum Federal

Exec Summary

DataBridge Solutions (the "Vendor") is pleased to respond to VA-OIT-2024-0389 for the Cross-Agency Data Sharing Portal. We bring demonstrated experience designing and operating high-availability, cloud-native platforms that process sensitive transactional data at scale, combined with a disciplined approach to secure architecture, FedRAMP High alignment, and accessibility compliance. Our proposed portal will replace the VA's fragmented legacy interfaces with a unified, RESTful, FHIR R4-compliant system hosted on a FedRAMP High-authorized cloud environment. Our team will apply DevSecOps practices throughout the full development lifecycle, from architecture design through ATO preparation and production operations. We will build the portal using React and Next.js for the front end, TypeScript for type safety, and a PostgreSQL-backed API layer, all integrated with VA's existing PIV-based multi-factor authentication infrastructure. Every API we develop will conform to OpenAPI 3.0 specifications and will be tested against both DoD and SSA system requirements before integration. We are committed to delivering a portal that meets or exceeds every in-scope objective in this RFP: secure role-based data exchange, FedRAMP High ATO prior to production, Section 508 and WCAG 2.1 Level AA accessibility, and full documentation and training deliverables. Our past performance on the Momentum Energy procurement platform demonstrates we can build and sustain platforms that handle high transaction volumes reliably, and we will apply those same engineering disciplines to this VA mission-critical effort.

Technical Approach

Task A — Architecture Design and Engineering: Within the first 30 days of award, our team will produce a System Architecture Document (SAD), Data Flow Diagrams (DFDs), and a Security Architecture Plan (SAP) aligned to NIST SP 800-53 Rev. 5 High baseline controls and VA Technical Reference Model (TRM) requirements. The SAD will define the portal's layered architecture, including presentation, application, data, and network layers, with explicit mappings to each applicable NIST control. DFDs will model every data flow between the VA, DoD, SSA, and portal components, identifying data classification, encryption requirements, and audit trail placement at each boundary. The SAP will document cryptographic control selections, boundary definitions, and the FedRAMP High control baseline. All artifacts will be reviewed and approved by the VA COR before development begins. Task B — Portal Development: The portal will be built on a FedRAMP High-authorized cloud environment on AWS GovCloud or Azure Government, consistent with VA infrastructure preferences established during pre-award discussions. The front end will use React and Next.js with TypeScript to enforce type safety and improve maintainability. The back end will use a RESTful API layer built on a PostgreSQL database, with FHIR R4 API endpoints for health record exchange and RESTful endpoints for benefits and service record exchange. All development will follow DevSecOps practices: code commits trigger automated security scanning (SAST/DAST) and infrastructure-as-code checks in a VA-approved CI/CD pipeline. Our team has direct experience operating cloud-native platforms at scale, including the Momentum Energy procurement platform, which sustained 99.9% uptime while processing more than $50 million in contracts in its first year of operation. We will apply those same reliability practices here, including automated health checks, structured logging, and alerting. Task C — API Development and Integration: We will develop, document, and test all APIs required for data exchange with DoD and SSA systems. Each API will conform to FHIR R4 standards for health records and RESTful conventions for benefits and service records. API specifications will be published in OpenAPI 3.0 format and maintained in a version-controlled repository accessible to VA and partner agency integration teams. We will conduct formal API integration testing against both DoD and SSA staging environments before any production data flows are established. Our data engineering team will design the PostgreSQL schema to support the required record types, enforce referential integrity, and support audit logging at the record level. All data exchanges will be encrypted in transit using TLS 1.2 or higher and encrypted at rest using AES-256. Task D — Security Assessment and Authorization (SA&A): Our team will prepare and maintain all documentation required for FedRAMP High ATO, including the System Security Plan (SSP), Plan of Action and Milestones (POA&M), Privacy Impact Assessment (PIA), and supporting artifacts. We will coordinate directly with the VA Authorizing Official (AO) and any third-party assessment organization (3PAO) selected by the VA throughout the assessment process. Our secure architecture practice is FedRAMP-aware, meaning we will design control implementations with ATO documentation requirements in mind from the earliest architecture phase, not as a retrofit. We will maintain a living SSP that reflects the current system state at all times, with POA&M items tracked and updated at each VA COR review cycle. Task E — Testing and Quality Assurance: Our QA process will cover four test levels: unit, integration, system, and user acceptance testing (UAT). Unit tests will cover all API logic and business rules. Integration tests will verify data flows between the portal and DoD and SSA systems. System tests will validate end-to-end workflows, including authentication, data exchange, and audit logging. UAT will be conducted with VA staff and designated federal partner representatives using realistic test data sets. All test artifacts — test plans, test cases, defect logs, and results reports — will be delivered to the VA COR in a structured, searchable format at each milestone. We will address all defects found during testing before any production release is submitted. Task F — Training and Documentation: We will deliver written end-user and administrator training materials covering portal navigation, role-based access workflows, and common troubleshooting scenarios. We will conduct at least two live training sessions, recorded and made available to VA staff. Our Section 508 and WCAG 2.1 Level AA accessibility practice will be applied to all training materials and the portal interface itself. The portal front end will meet WCAG 2.1 Level AA success criteria across all required conformance levels, and our accessibility review will be documented in a formal accessibility conformance report (VPAT) delivered to the VA COR.

Plain Summary

Our company builds software platforms that handle large amounts of sensitive information reliably. We are proposing to build a secure online system that lets the VA safely share Veteran health, benefits, and service records with partner agencies like the Department of Defense and Social Security Administration. The system will be hosted on a government-approved cloud, protected by strong security rules, and will meet all federal accessibility requirements so that VA staff and authorized partners can use it easily. We have already built and operated a high-traffic platform that processed over $50 million in transactions with 99.9% uptime, and we will use those same engineering practices here to make sure the VA portal runs smoothly from day one.

Exec Summary

The vendor proposes to deliver a secure, interoperable cross-agency data-sharing portal that meets FedRAMP High authorization requirements and enables authorized exchange of Veteran records between the VA, DoD, and SSA. The vendor's approach leverages cloud-native architecture on FedRAMP-authorized infrastructure (AWS or Azure GovCloud), implements role-based access control with PIV-based multi-factor authentication, and follows DevSecOps practices throughout the development lifecycle. The vendor's team has demonstrated the ability to build and operate high-availability, data-intensive platforms in regulated environments, achieving 99.9% uptime while processing complex transactions at scale. This proposal directly addresses the VA's stated objective to replace fragmented legacy interfaces with a unified portal that reduces latency, ensures data consistency, and eliminates current security vulnerabilities.

Technical Approach

The vendor's technical approach is organized around six core work streams that directly map to the RFP's in-scope tasks. Architecture Design and Engineering: The vendor will develop a detailed system architecture aligned with the VA Technical Reference Model and FedRAMP High control baseline (NIST SP 800-53 Rev. 5). The architecture will be documented through system context diagrams, data flow diagrams showing interactions between the VA, DoD, and SSA systems, and a comprehensive security architecture plan identifying threat models, cryptographic controls, and audit logging mechanisms. All design documentation will be reviewed and approved by the VA Authorizing Official prior to development commencement. Portal Development: The vendor will construct both front-end and back-end portal components using cloud-native patterns deployed on a FedRAMP High-authorized cloud environment (AWS or Azure GovCloud). The front-end will be built using modern web technologies (Next.js and React with TypeScript) to ensure type safety, maintainability, and compliance with Section 508 and WCAG 2.1 Level AA accessibility standards. The back-end will utilize containerized microservices deployed on managed Kubernetes infrastructure, with PostgreSQL as the primary data store. All infrastructure code will be version-controlled and deployable through a VA-approved CI/CD pipeline that enforces security gates and code quality checks at each stage. API Development and Integration: The vendor will develop RESTful and FHIR R4 APIs that enable secure, role-based data exchange with DoD and SSA systems. All APIs will be documented using OpenAPI 3.0 specifications in machine-readable format to facilitate integration testing and to support downstream integration work by partner agencies. API endpoints will enforce role-based access control (RBAC) consistent with the portal's identity management integration, log all requests for audit purposes, and implement rate-limiting and request validation to protect against common attacks. Security Assessment and Authorization (SA&A): The vendor will prepare and maintain all artifacts required for FedRAMP High Authority to Operate, including the System Security Plan (SSP), Plan of Action and Milestones (POA&M), security assessment reports, and evidence items mapping to each FedRAMP High control requirement. The vendor will serve as the primary technical liaison with the VA Authorizing Official and any third-party assessment organization (3PAO) selected by the VA, providing prompt responses to authorization questions and remediation of any findings identified during the assessment process. Testing and Quality Assurance: The vendor will execute a comprehensive testing program across four levels: unit testing (code-level validation), integration testing (verification of API interactions and data flows), system testing (end-to-end portal functionality), and user acceptance testing (UAT) conducted with VA stakeholders. All test artifacts—including test plans, test cases, execution results, and defect logs—will be delivered to the VA Contracting Officer's Representative. Testing will explicitly verify compliance with Section 508 accessibility requirements, FHIR R4 conformance, and FedRAMP High security controls. Training and Documentation: The vendor will develop comprehensive end-user and administrator training materials covering portal navigation, role-based access provisioning, audit log review, and incident response procedures. The vendor will conduct at least two live instructor-led training sessions with VA personnel, with scheduling aligned to the project milestone established at contract award. All documentation will be maintained in the VA's designated document management system and updated to reflect any post-authorization changes.

Plain Summary

We will build a secure online system that lets the VA, Department of Defense, and Social Security Administration safely share Veteran records with each other. Our system will use modern cloud technology (AWS or Azure) to store data safely, follow strict security rules from the federal government (FedRAMP High), and make sure only people with permission can see the records. We will make the system easy for Veterans employees to use and accessible for people with disabilities. We have built a similar system before (Momentum Energy) that stayed up and running 99.9% of the time while handling millions of dollars in transactions, which shows we can build reliable systems that handle sensitive data.
