I will develop embedded c firmware for stm32 microcontrollers with freertos

Are you looking for a reliable embedded firmware engineer with real production experience?

My firmware is currently running IN ORBIT on 4 live LEO CubeSat satellites including Drishti, launched on SpaceX Falcon 9 in May 2026. I bring the same mission-critical precision to every client project.

What I deliver:

• STM32 peripheral driver development using HAL and LL libraries (UART, SPI, I2C, CAN, RS-485, Ethernet)
• FreeRTOS-based firmware task design, ISR handling, queues, semaphores, mutex synchronisation
• OTA bootloader implementation with Secure Boot and Active/Backup slot failover
• Device driver development and hardware-software integration
• NVM and EEPROM parameter management
• Firmware debugging using JTAG, GDB, Valgrind, logic analyzer, oscilloscope
• Clean, commented, well-documented source code with README

My background:

• 3.5+ years of production embedded firmware experience
• Satellite COMMS firmware UHF, S-Band, X-Band subsystems
• Safety-critical systems KAVACH Indian Railways (RDSO CNR compliance)
• Built a complete UHF ground station from scratch as sole engineer

I work with:

STM32 F/L/H/WL series, FreeRTOS, Embedded C, UART, SPI, I2C, CAN, RS-485, Ethernet, MQTT, TCP/IP, UDP, Linux
