Firmware Engineer | Architecting High-Reliability IoT for Automotive & Healthcare | Bare-Metal C/C++ & RTOS Specialist

About

Firmware Engineer specialized in bare-metal C/C++ and RTOS-integrated IoT architectures. I focus on developing high-reliability telemetry for automotive safety and healthcare wearables where failure is not an option. Core Technical Stack: Languages: C, C++, Embedded C, Python. Systems: FreeRTOS, RTOS Architecture, I2C/SPI/UART/MQTT. Hardware: Raspberry Pi 4, ESP32-S3, LiDAR, GPS/GSM. Technical Impact: Automotive: Engineered a vehicle telemetry system with sub-200ms latency, validated through 2,000+ km of real-world road tests. Healthcare: Led a team of 4 to develop a LiDAR-based obstacle detection system, improving accuracy by 15%. Automation: Reduced sensor validation time by 90% (from 5 mins to <30s) using custom Python scripts.

Work experience

Firmware Engineer at I-FI, Sep 2025 - Present · 10 mos, Raigarh, Chhattisgarh, India, - Led a cross-functional team of 4 to transition an early-stage MedTech IoT prototype into a production-ready assistive wearable for the visually impaired, using rapid prototyping methodologies. - Engineered a high-fidelity obstacle-detection pipeline on Embedded Linux (RPi4) combining LiDAR point-cloud data with Edge-AI inference — achieved 15% higher detection accuracy through sensor fusion over baseline. - Interfaced ESP32-S3 over BLE (GATT profile) for low-latency sensor data relay to a companion mobile app, achieving <20ms round-trip latency — critical for real-time assistive feedback. - Integrated Firebase Realtime DB with GPS/GSM modules for mission-critical emergency location tracking, reducing emergency response latency for caregivers and first responders.

Automotive IoT Developer at Lairak Ai Telematic, Dec 2025 - Mar 2026 · 4 mos, Raigarh, Chhattisgarh, India, - Engineered a high-reliability vehicle telemetry system on Raspberry Pi — H.264 hardware-accelerated video encoding at sub-200ms latency for continuous dashcam capture. - Implemented a concurrent multiprocessing Python architecture (3 parallel processes) handling video encoding, sensor polling, and crash-safe persistence simultaneously — ensuring 100% data integrity during sudden vehicle power-loss events via software watchdog and atomic file-write patterns. - Validated system logic across 2,000+ km of real-world road tests, maintaining 99% uptime for sensor-triggered emergency alerts under diverse driving conditions. - Designed and hardened the firmware lifecycle with CI/CD pipeline integration, TDD practices, and GDB-based debugging — delivering a production-ready system from prototype to field deployment in under 4 months.

IoT Developer at Team Vikrant, Oct 2024 - Mar 2025 · 6 mos, Raigarh, Chhattisgarh, India, - Spearheaded a 6-member cross-functional team to deliver end-to-end IoT architecture for a high-performance Smart E-Bike competing in a national-level engineering challenge. - Architected a centralised Linux-based vehicle gateway (Raspberry Pi 4) integrating biometric/keypad access, real-time GNSS tracking, UART/I2C sensor fusion, and a live HMI dashboard for full bike telemetry. - Engineered a custom IoT protocol stack with geo-fencing, anti-theft immobilizer, and real-time mobile tracking — providing comprehensive remote vehicle management capabilities. - Validated system reliability through 50+ km of live field trials under real-world driving conditions, achieving 99%+ sensor data accuracy and zero critical failures during demonstration.
