About

Bare metal is where I live. For 2.5 years at TCS, I've been writing safety-critical firmware for automotive Battery Management Systems — directly on a TMPR454 (ARM Cortex R4-F), no RTOS, no abstraction layers, no margin for error. My work spans the full embedded stack: register-level peripheral configuration, interrupt-driven CAN J1939 communication, SPI/UART/I2C driver development, and system diagnostics compliant with ISO 26262 functional safety requirements. I enforce MISRA-C standards in production code and validate ECU behavior using CAPL scripting in Vector CANoe. What sets me apart: I've worked on legacy safety-critical code where every change requires understanding the full hardware-software interaction — a discipline that's hard to teach and rarer than most engineers realize. Now targeting Firmware Engineer / Embedded Software Developer /Automotive Embedded Systems Engineer roles in Automotive, EV, Semiconductor, or IoT — where bare metal competency, safety certification exposure, and hardware-close development are valued.

Work experience

Automotive Embedded System Engineer at Tata Consultancy Services, Oct 2023 - Present · 2 yrs 8 mos, Pune District, 1)Developed bare metal embedded firmware for automotive BMS on TMPR454 (ARM Cortex R4-F) with full register-level hardware ownership — no RTOS dependency — supporting deterministic real-time behavior across safety-critical EV charging and protection cycles 2)Implemented interrupt-driven CAN SAE J1939 communication stack from scratch, enabling reliable multi-ECU message exchange; validated against J1939-21 transport protocol specifications 3)Designed sensor data acquisition and diagnostics modules compliant with ISO 26262 ASIL requirements, directly contributing to system-level safety goal coverage 4)Reduced static analysis violation count by enforcing MISRA-C coding standards across the codebase in collaboration with QA and safety teams, improving audit readiness ahead of functional safety review cycles 5)Built and maintained a CAPL-based test automation suite in Vector CANoe covering CAN J1939 message scenarios, replacing manual test execution and reducing ECU validation time 6)Performed root-cause analysis on real-time interrupt latency and firmware defect investigations, restoring system stability in time-critical bare metal execution contexts
