## 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
