I will design and develop esp32, stm32, and nrf52 firmware for iot

I am a full-stack embedded systems engineer with 5+ years of hands-on ESP32 product development, from prototype to deployed commercial IoT hardware. I build production-grade ESP-IDF firmware that works reliably in the real world, not just on a breadboard. Feel free to check my portfolio for a quick view of my experience and capabilities.

Services include:

• ESP32 firmware development using ESP-IDF
• FreeRTOS-based multitasking applications
• State machine architecture design
• Wi-Fi and BLE applications
• MQTT, HTTPS, HTTP, WebSocket, and REST API integration
• Sensor and peripheral integration (I2C, SPI, UART, RS485, Modbus)
• Device provisioning via GSM, BLE or Wi-Fi
• OTA firmware updates
• ThingsBoard and Datacake IoT integration
• GSM, LTE, and cloud-connected systems
• Firmware debugging and optimization

What you will receive:

• Well-structured and maintainable source code
• Production-ready firmware architecture
• Technical documentation
• Reliable communication throughout the project

Your product deserves more than a proof of concept, let's build it for the real world.
