April 2025 – Present

• Supporting bring-up and post-silicon validation of the Vera TB500 platform, focusing on early silicon stabilization, farm-based validation, and deployment readiness.
• Leading bring-up and post-silicon validation of next-generation Tegra SoCs including T264 (Thor and Super Thor), T239 , T256 (Automotive/Client), and T254 (Client), driving SoC integration, silicon validation, and system stabilization efforts.
• Performing hardware-level debugging across GPU, CPU, memory, HSIO, power, and peripheral subsystems, including firmware validation, driver-level issue isolation, and system integration checks.
• Updating and validating dependent firmware components such as UFS, Display (O2 kit), Power Delivery (PD), Retimers, CX8/CX9, BMC, MCU, and other platform-specific firmware; coordinating with development teams to ensure timely fixes and stable integration.
• Working closely with BIOS teams to debug early boot-stage failures, capturing and analyzing boot logs, and providing detailed failure data to accelerate root cause resolution.
• Executing structured root cause analysis across hardware, firmware, kernel, and driver layers to isolate early-life and corner-case failures.
• Conducting environmental and reliability validation, including thermal testing from –40°C to 125°C, stress profiling, and cold/warm reboot cycling to ensure platform robustness.
• Running MODS-based GPU/CPU health checks, memory validation, and peripheral testing prior to regression and release cycles.
• Debugging and stabilizing hardware farm infrastructure across distributed lab environments, improving system uptime and validation throughput.
• Collaborating cross-functionally with Farm PICs, SIT, HSIO, Power, Speed, Software, BIOS, and firmware teams to manage dependencies and align debug efforts with project milestones.
• Supporting automation and regression workflows through Python-based validation in partnership with PyQual and automation teams, enabling scalable and remote test execution globally.
• Validating platforms across multiple operating systems including L4T, Ubuntu, Debian, and Windows on ARM, troubleshooting booting issues
• Taking ownership of assigned platforms and farm resources, proactively improving debug processes, documentation standards, and validation efficiency.

June 2021 – March 2025

• Led post-silicon debug and validation across Audio, TCSS (Type-C Subsystem), and DNT domains, resolving functional and component-level issues and providing data-driven feedback to design and firmware teams.
• Owned end-to-end issue triage and debug activities, meeting SLA commitments based on priority and customer impact while ensuring timely resolution and closure.
• Developed strong expertise in SoC bring-up flows, understanding interactions across hardware, BIOS, firmware, drivers, operating systems, and x86 architecture.
• Root-caused complex ADSP driver and Realtek codec issues spanning firmware, HDA, SoundWire (SNDW), and software stack layers.
• Debugged advanced audio scenarios including playback/record failures, noise, glitches, low-power audio (LPA), BIOS and endpoint enumeration issues across 3.5mm audio, Bluetooth/BT-LE, speakers, display audio, and USB headsets.
• Investigated application-level audio issues impacting platforms (e.g., Microsoft Teams, Alexa, Cortana), isolating driver, firmware, or OS-level root causes.
• Supported board bring-up and system-level debug, resolving Audio, TCSS, GFX, and DNT-related SNS issues including device enumeration, yellow bang (YB), and classification failures.
• Triaged and debugged Thunderbolt and USB-C issues involving Power Delivery (PD), retimers, USB4 host routers, USB 3/4 devices, Type-C docks, and Thunderbolt (TBT3/TBT4/TBT5 – Barlow Ridge) platforms.
• Utilized extensive low-level debug and trace tools including SST ETL, OS ETL, USB4 ETL, BIOS logs, PythonSV, PD logs, GFX ETL, Lecroy traces, Realtek dumps, AP4C logs, OEM DLL logs, MVA diagnostics, second-stage dumps, SoCWatch, Process Monitor, Windows Performance Analyzer, and WinDbg for BSOD/root cause analysis.
• Collaborated cross-functionally with BIOS, firmware, driver, silicon validation, and OEM teams to accelerate root cause identification and improve platform stability.
