Capabilities
The proof of an engineering shop is what it ships for itself. The engineers behind these capability areas build and operate NLT's own products — nltIMPACT running live in disaster response, nltDataInMotion moving mission data in real time — and bring the same production discipline to custom systems for agencies and enterprises.
Full-Stack Web Application Development
Modern web application development using React, Next.js, Node.js, and Python. Production deployments on AWS GovCloud and Azure Government.
API Design and Integration
RESTful and GraphQL API design, third-party system integration, and microservices architecture for federal and enterprise systems.
Database Engineering
Relational and spatial database design using PostgreSQL, PostGIS, Oracle, and SQL Server. Data modeling, migration, and optimization.
Platform Engineering and DevOps
CI/CD pipelines, containerization with Docker/Kubernetes, Terraform infrastructure-as-code, and cloud platform engineering.
Mobile Application Development
iOS and Android application development for field operations, data collection, and situational awareness use cases.
Legacy System Modernization
Migration of legacy systems to modern cloud-native architectures. Federal system modernization with maintained mission continuity.
Past Performance
