Worked on the balena-os/balena-generic repository to enhance the reliability of the modem subsystem, focusing on kernel-level stability for embedded systems. Addressed a critical race condition in the Linux MBIM driver by patching cdc_mbim.c, which resolved kernel panics during Cinterion ALAS5 modem initialization. This fix improved device uptime and reduced field failures related to cellular connectivity. Demonstrated expertise in driver development and kernel debugging using C, ensuring changes were integrated with minimal deployment risk and clear traceability. The work contributed to more stable balena-generic deployments, lowering support overhead and improving the overall reliability of embedded cellular connectivity solutions.
