We design, build, and sustain secure software systems that support essential federal operations. Our approach balances modern engineering practices with the realities of long-running government systems — ensuring reliability, accessibility, and compliance at every stage of the lifecycle.
Application Development
From modern microservices to large-scale enterprise platforms, we build secure, accessible, and high-performance applications designed for federal scale, longevity, and auditability.
- DevSecOps integrated throughout the SDLC
- Agile delivery aligned with federal governance
- API-first architectures for system interoperability
Mobile & Responsive Design
We design and build responsive, accessible digital experiences that extend federal services securely across devices — meeting Section 508 requirements and supporting users wherever the mission demands.
- Section 508-compliant UX/UI
- Progressive Web Apps (PWA)
- Secure native iOS & Android applications
Cloud &
Infrastructure
We help agencies modernize infrastructure with purpose. We design cloud and hybrid environments optimized for security, performance, cost control, and mission continuity — aligned with the NIST Cloud Computing Reference Architecture.
GovCloud CapabilitiesCloud Migration Strategy
Secure, phased cloud migration planning that accounts for security posture, operational readiness, and workforce impact across IaaS, PaaS, and SaaS models.
Data Center Modernization
Modernizing on-premise and hybrid environments through virtualization and optimized operations to improve resilience and efficiency.
AWS GovCloud & Azure
Deploying compliant, secure cloud environments on leading government-approved platforms.
Disaster Recovery & COOP
Designing resilient recovery architectures, failover strategies, and RTO/RPO plans to ensure uninterrupted mission operations.
Cybersecurity & Compliance
Security is not a phase — it is the foundation. We embed cybersecurity and compliance controls throughout the system lifecycle, ensuring federal systems meet the highest standards for confidentiality, integrity, availability, and audit readiness.
AI & Intelligent Automation
We help agencies apply artificial intelligence and automation where it delivers measurable operational value — without compromising governance, transparency, or human oversight.
Our AI solutions are designed for regulated environments, supporting decision-makers by reducing manual workload and improving consistency — not replacing human judgment.
Human-in-the-Loop Agents
Designing automation and agent-based workflows that support intake, routing, and processing — with mandatory human review for compliance-sensitive and mission-critical decisions.
Intelligent Document Processing (IDP)
Applying OCR and natural language processing to transform legacy documents into structured data, reducing manual entry, accelerating case workflows, and improving data accuracy in high-volume environments.
