Worked on the Samsung/TizenRT repository, focusing on embedded systems and firmware development using C and Assembly. Delivered a performance-oriented WiFi firmware Rate Adaptation mechanism switch to improve open space throughput, updating release packaging and metadata for traceability. Enhanced reliability by adding a safety counter to the WiFi TX Retry Count API, preventing infinite loops and reducing hang risks in the TX path. Addressed IPC host communication stability by replacing a busy-wait with a sleep-based delay, enabling context switches and preventing device hangs. Demonstrated a methodical approach to system programming, emphasizing reliability, maintainability, and clear audit trails in real-time environments.

Feb 1, 2025February 2025 — Samsung/TizenRT Key features delivered: - WiFi TX Retry Count API Safety: added a safety counter to prevent infinite loops when retrieving TX retry information (commit f6d2a895635cc94fbff9d6282a5697f56955b9a8). Major bugs fixed: - Prevented infinite loop in TX retry info retrieval by enforcing a termination condition; reduces hang risk in the WiFi path. Overall impact and accomplishments: - Boosted reliability and uptime of the WiFi subsystem on the RTL8730E-based Samsung/TizenRT platform. The change provides safer, more predictable behavior under retry scenarios and improves maintainability with a clear, auditable commit. Technologies/skills demonstrated: - Embedded C firmware development, debugging and fault-tolerance design, safety-counter pattern, code review and change-tracking in a real-time operating system context.
