Worked on the espressif/esp-dl repository to modernize security APIs and improve build stability for ESP-IDF v6.0 and above. Migrated AES encryption to the PSA Crypto API, while maintaining backward compatibility with earlier ESP-IDF versions through conditional compilation and legacy mbedtls support. Addressed build errors affecting Kalman filter modules by updating the esp-dsp dependency to version 1.8.0, ensuring continued functionality across ESP-IDF releases. Demonstrated strong skills in C++ development, cryptography, and dependency management, with a focus on embedded systems. The work enhanced security posture, streamlined upgrades, and preserved feature availability for Kalman-filter-based modules in evolving environments.

Apr 1, 2026Month: 2026-04 — Espressif/esp-dl focused on security API modernization and build stability for ESP-IDF v6.0+. Key outcomes include: - Features delivered: Security API modernization: Move AES encryption to PSA Crypto API for ESP-IDF v6.0+ with compatibility for older ESP-IDF via mbedtls. Commit: 633babe4cd960ff3726ced214623dd4024814e34. - Major bugs fixed: Kalman filter build compatibility: Updated esp-dsp to 1.8.0 to resolve build errors related to Kalman filter modules on ESP-IDF v6.0. Commit: e437d914d38924099da07d30cbfedeed0940c463. - Additional resilience: Compile-time version detection selects PSA Crypto API for IDF >= 6.0 and falls back to legacy mbedtls for IDF < 6.0, preserving compatibility and simplifying upgrades. - Impact and accomplishments: Improved security posture and forward compatibility with ESP-IDF v6.0+, reduced build-time failures, and maintained feature availability for Kalman-filter-based modules. Demonstrated strong dependency management and forward-looking crypto API strategy. - Technologies/skills demonstrated: PSA Crypto, ESP-IDF 6.0+, mbedTLS compatibility, esp-dsp, Kalman filter integration, conditional compilation, build system resilience.
