Message

At Tech Mahindra Limited, I contributed to Airbus’s Cargo Door Access System by implementing and maintaining low-level HAL and peripheral drivers for the TI TMS320F28335. I also developed firmware interfaces for board-level peripherals and supported hardware integration and validation.

For an industrial liquid dispensing system, I developed firmware enhancements for motor control and the HMI, including soft ramp-up, controlled dispensing, ramp-down, and anti-drip control. I also added a FreeRTOS task for dispense flow control, volume accumulation, and timing.

Earlier, at Sirveen Control Systems Pvt. Ltd., I worked on an emergency talkback system with full-duplex audio over Ethernet, using MULAW compression and audio storage on SD cards. At Centrex Telecom, I developed firmware for EPABX and intercom systems, including a 192-line system and its master–slave communication.
