PROFILE

Greg Spencer

Developed core features and architectural enhancements for the flutter/genui repository, focusing on AI-driven UI generation and modular platform scaffolding. Leveraged Dart and Flutter to implement a dynamic UI elicitation framework, enabling JSON-based UI composition and chat-driven workflows. Refactored the core and transport layers to introduce a reactive, catalog-based API, improving separation of concerns and extensibility. Integrated Firebase for cross-platform readiness and enhanced build configuration, while updating documentation and test infrastructure to support maintainability. Addressed memory management and stability through targeted bug fixes and code cleanup, resulting in a more reliable, production-ready foundation for AI-powered UI development.

February 2026: Delivered foundational GenUI v0.9 upgrade and major architectural enhancements across flutter/genui, with a focus on modularity, reliability, and performance. Implemented a reactive, catalog-based ClientFunction model, refactored core and transport layers, and aligned A2UI integration with the new core. Substantial UI surface and modal refactors, plus a Conversation facade for simple_chat integration. Updated examples and infra tooling, performed extensive test improvements, and removed legacy packages to enable a safer upgrade path. Result: clearer separation of concerns, reactive data flow, easier extension points, and improved stability for production deployments.
