Work History
System Technical Architect
AUMOVIO (Continental Automotive Private Limited)
Bengaluru
07.2023 - Current
- Worked on camera bring-up on automotive SoCs, enabling data flow from camera sensor to memory using V4L2 and DMA. Improved performance by reducing CPU usage and increasing data throughput.
- Enabled Linux BSP bring-up and HPC benchmarking on automotive HPC SoCs ( NVIDIA AGX Xavier & Orin, NXP S32G2, Rnesas, imX51) to Improved system performance and efficiency for multi-core workloads under high load. (Ubuntu and Debian based Distribution).
- Designed persistent data logging mechanism using circular buffer structures, ensuring reliable storage and retrieval of critical system data across reboots.
Principal Engineer,
Toshiba Software India Private Limited
Bengaluru, India
12.2021 - 05.2023
- Implemented secure boot on Skelios (Debian 9/10) across ARM64 (TF-A + U-Boot FIT) and AMD64 (UEFI Secure Boot + GRUB), enforcing hardware-rooted chain-of-trust from firmware to user space.
- Integrated Debian package signing with boot security and validated via tamper testing to ensure end-to-end system integrity.
- Performed CVE analysis and triaging on Selios image (Debian Based Distribution), identifying root cause via patch diffing and debugging, and validating fixes to ensure timely vulnerability mitigation.
- Brought up and optimized the Gianfar Ethernet driver on ARM64 Linux, enabling DMA-based Tx/Rx paths and improving throughput via NAPI and interrupt tuning.
- Performed package compliance management on Slelios (Debian based distribution) platforms by downgrading GPLv3-licensed components to acceptable versions, ensuring license adherence and mitigating known security vulnerabilities.
Technical Lead,
Radisys India Private Limited
Bengaluru, India
10.2019 - 10.2021
- Designed platform monitoring and reliability framework (rsys_watchdog) for service health tracking and system stability.
- Developed secure upgrade/downgrade mechanisms for ONL images with rollback and backward compatibility across Debian-based systems.
- Implemented low-level I2C CPLD driver for hardware control (LEDs, PON/NNI, FPGA) with GPIO-based configuration.
- Led Debian (8/9) packaging and ONL image integration, enabling reproducible builds and deployment consistency.
- Enhanced system security via audit logging, Nessus-based vulnerability analysis, CVE patching, and OSS compliance fixes.
- Improved system reliability using Valgrind and Klocwork for memory leak detection and static analysis; resolved field and DV-reported issues.
- Handled platform bring-up, hardware validation, integration, and release verification for production readiness.
- Worked on OpenWRT-based embedded platform for broadband/edge networking use cases in PON environments.
- Debugged and optimized Linux networking drivers (Ethernet / PHY / DMA) in OpenWRT.
Senior Software Engineer,
