• Android platform development and AOSP customisation.
• Linux kernel configuration tuning and performance optimisation.
• Scheduler tuning latency reduction and power management improvements.
• Modifying Android framework services and system components.
• Working within large-scale codebases using Git (branching merging upstream integration).
• Integration of open-source tools for debugging profiling and performance analysis.
• Development of system-level C components in real-time multi-threaded environments.
