Do IoT Device Programming and Embedded System Design for ESP32 STM32 Arduino MCU
Looking for reliable IoT Device Programming and Embedded Systems Design? I build connected devices that work.
I program and design embedded IoT systems for ESP32, STM32, and Arduino MCUs from hardware level driver code to full wireless cloud connectivity. Designed to perform in the real world.
SERVICES INCLUDED:
- IoT device programming WiFi, BLE, LoRa
- Embedded systems design & architecture
- ESP32, STM32 & Arduino MCU firmware
- I²C, SPI, UART peripheral drivers
- MQTT, HTTP & cloud API integration
- Low power IoT device design
WHAT YOU GET:
- Fully tested, production ready firmware
- 100% source code ownership
- Free revisions until it's perfect
Your IoT device needs programming done right the first time. That's my specialty.

FAQ
What does 'IoT Device Programming' include?
IoT device programming covers everything from MCU-level sensor reading and peripheral control to wireless communication, cloud data publishing, and remote command handling. I program the full device stack so your hardware connects, communicates, and responds reliably.
What wireless protocols can you implement for IoT devices?
I implement WiFi (TCP/IP, HTTP, MQTT, WebSocket), Bluetooth Low Energy (BLE GATT profiles), LoRa/LoRaWAN, Zigbee, ESP-NOW, and cellular IoT (LTE-M/NB-IoT with compatible modules). Tell me your connectivity requirement and I'll confirm scope.
Can you design the embedded architecture for my IoT product?
Yes. I design the embedded system architecture MCU selection rationale, peripheral mapping, communication strategy, memory layout, and power management approach before writing a single line of code. Good architecture prevents expensive rewrites later.
How do you handle low power design for battery IoT devices?
I implement deep sleep, light sleep, and wake on interrupt strategies. I optimize duty cycles, reduce active current draw, and schedule wireless transmissions efficiently. Battery powered IoT devices get firmware tuned for maximum runtime without sacrificing reliability.
Can you connect my IoT device to a mobile app?
Yes. I implement BLE GATT services for direct mobile connectivity and MQTT/HTTP for cloud-based app integration. I provide the BLE service UUIDs or API endpoints your app developer needs to communicate with the device firmware seamlessly.
Do you support multi sensor IoT device programming?
Yes. I integrate multiple sensors in a single firmware build temperature, humidity, accelerometer, GPS, pressure, RFID, ultrasonic, current, and more. Each sensor gets proper driver code over I²C, SPI, UART, or ADC depending on its interface.
What if my IoT device needs to handle firmware updates remotely?
OTA (Over-The-Air) firmware updates are included in Premium and available as add-on for Standard. I implement secure OTA via HTTP or MQTT with update validation, rollback protection, and version checking essential for deployed IoT products.
