PROFILE
Miguel Ruiz De Sotto
Contributed to the LedgerHQ/ledger-secure-sdk repository by delivering targeted improvements in embedded systems and build configuration. Enhanced the NbglRadius enumeration to better represent pixel values and aligned the Python nbgl_lib.py library with its C counterpart, streamlining cross-language API consistency. Centralized the REVAMPED_IO definition within the build system, reducing configuration drift and simplifying future I/O architecture changes. Addressed protocol robustness by introducing a dedicated SEPROXYHAL_TAG_INVALID define, standardizing error handling for invalid tags. Demonstrated proficiency in C programming, Makefile-based build systems, and Python scripting, with a focus on maintainability, defensive programming, and careful, low-risk integration of new features and fixes.

Jun 1, 2025June 2025: LedgerHQ/ledger-secure-sdk—architectural stabilization of the I/O subsystem. Centralized the REVAMPED_IO definition by moving it from Makefile.rules to Makefile.defines, unifying the I/O architecture and simplifying build configuration. This reduces configuration drift, improves maintainability, and sets the stage for future I/O refactors. The change is build-system focused and does not alter external behavior. Commit 96951f29066bda05d93a01594e79d79e380c630b documents the change.

Feb 1, 2025February 2025 — LedgerHQ/ledger-secure-sdk: Key features delivered: NbglRadius Enumeration Enhancement and Python-C Library Alignment. Adds new NbglRadius options and reorders existing ones to better reflect available pixel values; ensures consistency between the Python nbgl_lib.py library and the underlying NBGL C library (commit 65e05013ffa10e898a348e55ddc40cbc56848d08). Major bugs fixed: None identified this month. Overall impact and accomplishments: Improved cross-language API consistency between Python and C NBGL bindings, reducing potential misuse and boosting reliability of NBGL-based UI components. Alignment simplifies future maintenance and cross-language development. Technologies/skills demonstrated: Python-C interoperability, API enum modernization, NBGL library synchronization, maintainability and careful change management.
