Are you looking at Senior Embedded System Engineer? just Me!
I am a senior embedded systems & firmware engineer with deep expertizing MCU, especially ESP32, STM32, Raspberry Pi. Over 10years of experience in embedded fields, I successfully build over 50 product-ready, mass-producing level firmware and embedded real time systems. With this strong background, I can successfully help your jobs in embedded field.
What I Do ESP32 firmware design using ESP-IDF or Arduino framework Implement Wi-Fi (TCP/IP, HTTP, MQTT) and Bluetooth/BLE connectivity Integrate sensors, peripherals, and communication interfaces (SPI, I2C, UART, ADC, PWM, etc.) Develop OTA update systems and secure data encryption (SSL/TLS) Optimize firmware for power efficiency and real-time performance IoT cloud integration (AWS IoT Core, Azure IoT Hub, Google Cloud IoT) Debugging & testing using JTAG, UART logs, and logic analyzers End-to-end IoT solutions — from prototyping to deployment
ESP32 & ESP-IDF Expertise I have extensive hands-on experience with ESP32 and ESP-IDF, developing and maintaining production-grade firmware for IoT and industrial applications. I have successfully: Migrated projects across major ESP-IDF versions (4.x → 5.x), resolving API, driver, and build system changes. Implemented Wi-Fi, BLE, OTA updates, MQTT communication, and optimized FreeRTOS multitasking. Camera Integration and Edge AI/ AIoT firmware Customized drivers and HAL layers for unique sensor/actuator requirements. Applied low-power design techniques and optimized memory, flash, and peripheral usage. Debugged and profiled firmware using PlatformIO, OpenOCD, and ESP-IDF Monitor tools.
Let’s Build Something Smart If you need a firmware engineer who truly understands ESP32, IoT, and embedded systems — let’s connect. I can help bring your smart device or connected product to life.
