• Improved existing features, fixed performance issues, kernel crashes, memory leak issues, race condition issues, ported features across different architectures/kernels and created automated suites.
• Fixed reported defects across various modules of the 802.11n and 802.11ac Wireless Access Point driver such as Self Organizing Networks, Band steering, Multi-Band optimization and open source hostapd/supplicant.
• Reduced 3.6% RAM usage in Wi-Fi chipsets by optimizing the data structures.
• Increased 20% performance of device driver interaction with the hardware.
• Was part of design discussions for the proprietary Wi-Fi specifications and implemented one of its core features using timers in SMP architecture that saves about 70% contention time in a large user environment.
• Re-architected the code to group the loadable kernel modules according to the layers in the network stack saving 17% flash memory in most of the use case.
• Core member of product release team. Suggested and implemented TDD workflows internally to reduce 40% bugs post release. Improved existing features, fixed critical bugs and created automated suites to find the regression point.
• Maintainer of the proprietary configuration library invoking the kernel IOCTLs.
