Hire the Best Firmware Engineers
in Bangladesh

Firmware is where most IoT projects stall — not at the concept stage, but in the gap between a working prototype and a device that runs reliably in the field for years. That gap is where I work. I build production-grade embedded firmware for consumer IoT and utility management devices. My focus is reliability, low power, and owning the full firmware stack: from peripheral drivers and RTOS architecture through to OTA update pipelines and cloud integration. With 8+ years of experience across the full development cycle, I'm comfortable taking a project from board bring-up to field deployment, or stepping in as a senior contributor on an existing team. CORE SKILLS: Platforms: Nordic nRF52, ESP32, STM32 RTOS: Zephyr, FreeRTOS Wireless: LoRaWAN (AWS, TTN, Senet), LTE-M (Quectel), WiFi, BLE Protocols: MQTT, Modbus, HTTP, mbedTLS, TCP/IP OTA & Bootloader: MCUboot, FOTA Power Profiling: Joulescope, nRF PPK-II Cloud: AWS IoT Core, The Things Network Debugging: Oscilloscope, Logic Analyzer (Saleae), Analog Discovery 3, Spectrum Analyzer Other: LVGL GUI, I2C, SPI, UART, DMA, I2S, ADC/DAC If you're building a device that needs to run reliably in the field for years — let's talk.

Hi, I started my career on Electronics since 2006. Done many successful projects that includes various kinds of Micro Controllers Programming, PCB Design & Product Implementations. From 2014 I am implementing my knowledge in Industrial field. I can implement my experience and knowledge to every kind of electronics available now a days.

To use my skills, experience, and adaptability to obtain a programming position where I am constantly challenged. My greatest strength is my ability to walk into a new environment and be functional immediately. I am quick to learn and adapt to new situations, configurations, and technologies. My greatest strength is my ability to walk into a new environment and be functional immediately. I am quick to learn and adapt to new situations, configurations, and technologies. I am proficient in a couple of programming languages, with C being my backbone and a Python lover. I enjoy solving hardware problems that have performance constraints, limited memory resources, or tight timing. I have Eight years of electronic circuit debugging experience. I use Git as version control for my work and Trello for project management. I am working with embedded systems such as FPGA, microcontroller programming, PCB design, circuit design and Android Programming as well.

I am a hardware and embedded systems engineer specializing in rapid prototyping and custom electronics, transforming ideas into fully functional prototypes. With hands-on experience in firmware development for STM32, ESP32, and Arduino, as well as PCB design, I have successfully delivered solutions in various fields, including IoT, automotive, agriculture, and low-power applications. I offer comprehensive support, from concept and prototyping to production-ready solutions. My focus is on ensuring reliability, clear communication, and fast turnaround at every stage of the process. Let’s bring your idea to life! Just send me a message to get started.

I'm a Computer Science and Engineering student at the Rajshahi University of Engineering & Technology (RUET). Furthermore, I am a competitive programmer and a freelancer. Working with Arduino and embedded systems is something I'm passionate about. A mechanical ventilator project launched my career in this industry. After that, I worked on several Arduino, ESP8266, and ESP32 projects. I've worked with Arduino-based systems for two years. I have completed several mega projects, including an automatic Ambu bag-based medical ventilator, bee-hive monitoring, and controlling system, a CPAP-BiPAP ventilator, an environmental pollution monitoring system, an IoT-based soil moisture monitoring and controlling system, and an IoT-based dog tracking system, to name a few. Apart from that, I can create Android and Web applications. I've previously worked on Android apps like Bluetooth-based ventilator monitoring and control, BLE-based distance measurement systems, WiFi-based home automation apps, and web apps like IoT-based dog tracker projects. I've worked with Android apps using Java and Flutter before. I'm currently working on machine learning with TensorFlow.

My childhood hobby was taking something apart and putting it back together. As I grew older, I became fascinated with electronics and completed BSC on EEE. Over the last 10 years I have developed some consumer and IoT products for RISO, ME-Solshare Ltd, Walton Micro-Tech Corporation, Sinetek Ltd, ERROR Lab and I've acquired some rather unique skills along the way in embedded systems, RF/wireless, and harsh environment systems. In most of my projects I have developed firmware using TTD (Test-driven development), maintained firmware versions properly by git and followed industry best practices.
