July 2026 — Zephyr4Microchip/zephyr: Delivered cross-architecture TLS relocation support in the LLEXT loader (AArch64 local-exec TLS), including TLS section handling and test coverage (llext.tls). Fixed two critical issues: haptics syscall verification level type alignment (uint8_t -> uint32_t) to resolve marshalling/compile errors, and UART0 CTS pinmux in Broadcom device-tree to restore proper CTS/RTS flow control on Pi Zero 2 W. These changes improve stability, portability, and hardware interoperability, while demonstrating proficiency in C/C++, ARM64, TLS relocation, and kernel-level device-tree work.

May 2026: Delivered cross-SoC hardware integration and reliability improvements across Zephyr-based platforms. Key items include enabling the ARM architected timer driver on non-GIC arm64 SoCs via custom interrupt controller support; RFC 6455 WebSocket subprotocol echo during upgrades; UART reliability fixes for BCM2711 to prevent deadlocks and preserve interrupt state; and SDIO CMD53 block transfer validation to enforce the 511-block limit per spec, preventing register corruption.
