L&C
L&C needed a secure middleware layer to sit in front of a critical API, with the design and implementation handled carefully enough to meet a high security bar without adding unnecessary complexity.
Project highlights
Designed the middleware architecture for a security-sensitive API integration.
Implemented the solution in TypeScript and Node.js.
Delivered the work with security treated as a first-order engineering concern.
Challenge
Because of the sensitivity of the system, the work needed to stay deliberately abstract externally while still meeting strict technical and security requirements internally. The middleware had to be robust, dependable, and designed in a way that reduced risk across authentication, request handling, and service-to-service communication.
Approach
We led the design and technical implementation of the middleware in TypeScript on Node.js, shaping the architecture, defining the API interaction layer, and building the core logic with security as the primary concern throughout. That meant making deliberate design choices around structure, reliability, and defensive implementation rather than treating security as an afterthought.
Outcome
The result was a secure middleware layer that gave L&C a stronger foundation for handling API traffic, with the technical design and implementation aligned around reliability, maintainability, and a high level of security.
Project summary
Designed and built a secure TypeScript middleware layer to protect and structure access to a critical API.
