Work History

Staff Engineer

Qualcomm India Pvt Ltd
Hyderabad
03.2016 - Current
  • WLAN Data-path Design and Development
  • It includes:
  • Rate Control Algorithm
  • WLAN TX/RX path
  • IEEE802.11ac/ax, NAN, P2P, XPAN etc.
  • Worked on the development of following feature:
  • Green-Tx to dynamically reduce Tx power
  • Secondary Retry Rate to ensure robustness of WiFi frame.
  • Smart Tx Chain-mask support.
  • Multi-Link Operation at STA side.
  • 2 off-channel support in NAN protocol
  • Several code optimizations to improve performance.
  • Developed framework to test and validate WLAN FW Data-path code.
  • Information security project:
  • Design a solution to establish secure communication between 2 SOCs preventing side-channel attack.

Senior Software Engineer

MediaTek
Noida
10.2013 - 02.2016
  • WLAN Protocol Development
  • Developed full MAC Wi-Fi driver for IoT product with Wi-Fi and BLE solution. It includes implementation of features like 11n support, security, 20/40MHz support, Coexistence-20/40, OBSS scanning, Partial Scan in AP mode, defragmentation support, AP Client, Repeater.
  • Design and development of IEEE802.11af protocol which includes TVWS MLME state machine design and implementation like Enablement, CAQ, CSM, CVS. Implemented proprietary features like dynamic bandwidth selection, TVWS scanning algorithm. Integrate TVWS driver with Open-WRT on MIPS platform. Successfully demonstrated this solution in National Taiwan University. Developed QA tool for HQA team.

Software Engineer

Sasken Communication
Bengaluru
10.2011 - 10.2013
  • WLAN Driver Development
  • Developed Adaptive Transmit Power control algorithm
  • P2P solution: This solution is designed to enable 2 peer station STA1 and STA2 to transmit data packet directly to each other in infrastructure network. In this both STA will listen Wi-Fi medium and learn presence of each other by maintaining MAC address, power save status and other important information associated with peer STA. Once this information STA2 is added in STA1's linked-list and STA1 in STA2's linked-list, it can send data packet directly to each other without going through AP which almost doubles throughput.
