Our team joined Lexgen’s technical steering group to assist in architecting the backend for performance and modularity. We helped wrap their LLM-based engines into secure, API-driven services and built infrastructure to allow jurisdictional toggling and context caching for faster load times. On the front end, we delivered a minimal but powerful interface with intelligent query refinement, multi-result previews, and on-hover citation checks. A special focus was placed on GDPR compliance, with encrypted session handling, audit logs, and controlled document ingestion. We also built a lightweight admin portal to let non-technical users manage content modules and test AI behavior in sandboxed environments.
