PROFILE
Diogo Sousa
Montez de Sousa developed and enhanced backend features for the OpenBB-finance/backends-for-openbb repository over six months, focusing on document delivery, AI integration, and robust API design. He implemented PDF and whitepaper widgets with cloud storage via AWS S3, improved multi-file viewer capabilities, and integrated Gemini and Google GenAI for prompt processing. Using Python, FastAPI, and Pydantic, Montez emphasized data modeling, error handling, and configuration management to ensure maintainable, production-ready code. His work addressed file access reliability, CORS security, and environment consistency, demonstrating depth in backend engineering and delivering scalable solutions that improved both user experience and developer workflows.

Apr 1, 2025April 2025 accomplishments for OpenBB-finance/backends-for-openbb: delivered the Gemini LLM Widget (Gemini API) with end-to-end integration, including root/config/prompt endpoints, data models, and robust error handling, plus system configuration updates to support the widget. Also released Multifile Viewer UI improvements and completed a naming refactor to rename fileSwitcher to fileSelector for clarity. Major bugs fixed: none reported this month; stability gains came from UI refinements and refactors. Overall impact: enables AI-assisted prompts, richer multi-file exploration, and improved maintainability to support scalable widget integrations. Technologies demonstrated: API design, data modeling, error handling, UI component updates, configuration management, and clean code refactoring.
