Worked on the flipperdevices/flipperzero-firmware repository, focusing on improving the reliability of record handling within embedded systems firmware. Addressed a critical bug by implementing validation for non-NULL data pointers in the furi_record_create function, which prevents potential NULL dereference issues when furi_record_open could return NULL. This change enhanced the robustness of the firmware workflow and enforced stricter API contracts. Updated the developer documentation to clarify the new non-NULL data pointer requirement, ensuring clear expectations for contributors. Utilized C and embedded systems expertise to deliver targeted improvements, prioritizing data integrity and stability in firmware development over the course of the month.
