Rafael Lyra developed and maintained advanced control and monitoring features across the lnls-sirius/hla and mxcube/mxcubecore repositories, focusing on automation, reliability, and maintainability. He redesigned user interfaces for control windows, refactored legacy modules, and integrated real-time monitoring using Python, PyQt, and Kafka. Rafael implemented robust API surfaces and enhanced error handling, supporting both hardware integration and experimental workflows. His work included streamlining configuration management, improving data validation with Pydantic, and introducing asynchronous programming patterns. The depth of his contributions is reflected in the breadth of features delivered, bug fixes, and the improved stability and scalability of the codebase.
January 2026 focused on reliability, observability, and maintainability for MXCuBE's Bluesky-driven workflow. Delivered key features to improve automation and monitoring, strengthened error handling, and cleaned up legacy code to reduce risk and accelerate development. These changes enhance experiment throughput, reduce downtime, and provide clearer visibility into plan execution and system state.

December 2025 focused on strengthening motor/actuator reliability, API stability, and experimental capabilities while improving observability and maintainability. Key outcomes include faster, more robust EPICS motor control, stabilized API surfaces for EpicsActuator/EPicsMotor, and extended support for diffraction experiments via LNLSDiffractometer. These changes reduce downtime, enable more automated workflows, and broaden instrument capabilities for the lab.

November 2025: Focused on strengthening monitoring capabilities and data validation to boost system reliability and user responsiveness. Delivered Intlk9 PV monitoring enhancement for real-time interlock tracking (frequency > 2Hz) with UI updates in SummaryWidget and PUDetailWidget, improving detection of triggering conditions and operator visibility. Fixed ICATLIMS parameter handling by converting session_id, proposal_id, and nb_shifts to strings to satisfy Pydantic validation, eliminating runtime type errors and aligning with API contracts. These changes reduce downtime, improve data integrity, and support scalable monitoring and intake workflows. Technologies include Python type validation, Pydantic, UI widget integration, and event-driven monitoring logic.

Month 2025-10 — mxcubecore LNLS Module Cleanup delivered to streamline configuration and reduce maintenance burden. Removed obsolete LNLS configuration (lnls_sol directory and contents) and deprecated hardware object classes, aligning with the updated configuration strategy. Changes supported by two targeted commits: removing lnls_sol from configuration and cleaning up LNLS hardware objects. Result: reduced configuration drift, lower risk of misconfiguration, easier onboarding for LNLS integrations, and improved future maintainability.
