I will develop automotive firmware systems for j1939 and obd2 ecus

Looking for an embedded software expert to program your automotive networks? I specialize in developing high-reliability, production-grade firmware for electronic control units (ECUs), vehicle telematics, and diagnostic gateways.

I write clean, efficient C/C++ source code optimized for real-time operations, deterministic network processing, and automotive fail-safe conditions.

My Firmware Expertise Includes:

• CAN Bus communication protocol, CAN FD, and LIN bus systems
• OBD2 parameter identification (PIDs) and mode diagnostics
• J1939 parameter groups (PGNs) and suspect parameter numbers (SPNs)
• Unified Diagnostic Services (UDS ISO 14229) implementation
• Microcontrollers: STM32, ESP32, NXP, Microchip, and Arduino

What You Will Receive:

• Clean, well-commented source code tailored to your target MCU architecture
• Compiled binary/hex files ready to flash directly onto your device hardware
• Comprehensive test validation logs via CAN tools like SavvyCAN or Busmaster
• Complete register documentation and API references for system integration
