• Developed embedded firmware in C for a modular real-time display system on Raspberry Pi 5 running Alpine Linux — integrated Quectel EC200U 4G LTE module, Ethernet TCP/IP stack, and RS485 communication protocol for live traffic management infrastructure.
• Wrote low-level peripheral drivers for RS485 and UART interfaces — configured GPIO, hardware interrupts, and protocol handlers for an 8-channel lamp monitoring input card transmitting real-time fault data across distributed traffic nodes.
• Designed layered firmware architecture separating hardware drivers, protocol handling, and application logic — reduced debugging time and enabled faster feature updates across the deployed system.
• Developed complete firmware pipeline for a P10 LED display system (2×3 matrix) — implemented data parsing, refresh cycle control, and real-time speed visualization for vehicle-actuated traffic displays.
• Debugged hardware and firmware issues on live deployed systems using oscilloscopes and logic analyzers — identified and resolved RS485 signal integrity issues caused by missing termination resistors, restoring reliable data transmission.

Embedded Engineer - Sharang Shakti - Gurugram, India

(2024-06 - 2025-01)

• Developed bare-metal firmware in C++ for a custom drone flight controller — wrote SPI peripheral drivers for BMP390 and BMP585 barometric pressure sensors and Xsens MTi 9-DOF IMU, and UART driver for NEO M9N GPS module; achieved stable real-time multi-sensor fusion under dynamic flight conditions.
• Designed Power Distribution Boards (PDBs) for 12V and 3.3V power rails using LM76005 and TPS564257 synchronous buck regulators — performed component selection, inductor sizing for 30% ripple current, output capacitor ESR analysis, and thermal validation on bench.
• Conducted systematic hardware validation and bench testing — used oscilloscopes to verify SPI/UART waveforms, measured output voltage ripple, and iterated firmware configurations to resolve real-time sensor data errors.
• Produced technical documentation including firmware architecture, driver API specs, component datasheets, and deployment guides for cross-functional hardware and software teams.
