Own end-to-end firmware QA for embedded satellite hardware: design and build HIL test rigs, automate regression suites with Python, correlate logs across debug probes and device interfaces, define release validation gates, and scale QA processes for hardware products.

Design, implement, and validate embedded firmware for resource-constrained devices (ARM Cortex-M) using C/C++/Rust and Zephyr. Develop device drivers, communication stacks (satellite, LTE, Bluetooth, mesh), optimize power and real-time performance, support board bring-up and hardware debugging, and build CI/CD and HIL test infrastructure.
