Let’s bring your idea to life! Just send me a message to get started.

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.

Experienced Embedded Systems & IoT Engineer Hi there! I’m a passionate Embedded Systems and IoT Developer with over 4 years of experience bringing hardware ideas to life. I specialize in building end-to-end solutions using micro controllers like Arduino, ESP32, and ESP8266 and I’m deeply involved in everything from firmware development to custom PCB design. I’ve spent years working with a wide range of technologies to create seamless user experiences: Interfaces & Displays: Designing intuitive controls using OLED, TFT, Nextion, and Matrix displays. Connectivity: Integrating GSM, GPS, Wi-Fi, and Bluetooth for smart, connected devices. Cloud & Backend: Building real-time monitoring systems using Firebase, MQTT, Blynk, and MySQL/PHP. Prototyping: Utilizing Wokwi and Tinkercad to ensure designs are flawless before they hit the bench. What I bring to your project: I don’t just provide code; I deliver a complete, functional package. You’ll receive clean C/C++ or .ino source code, detailed circuit diagrams, and simulation files where applicable. Most importantly, I provide the expert advice needed to ensure your project is reliable and scalable. I’m a firm believer in "measure twice, cut once," so please feel free to contact with me. I’d love to discuss your vision for free and make sure we’re the perfect fit for a successful collaboration! Looking forward to building something amazing with you.

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.

I help startups and companies design reliable embedded hardware—from schematic to PCB to firmware—ready for manufacturing. *STM32 / ESP32 / ESP8266 *2–6 layer PCB | IoT | Power & Mixed-Signal *Hardware + Firmware Integration What I can help you with: • Embedded hardware design (schematic + PCB) • STM32 / ESP32 firmware (SPI, I2C, UART, CAN, Wi-Fi, BLE) • IoT devices, sensor systems, automation boards • DFM / DFT-ready PCB for manufacturing • Debugging & board bring-up Tools: • KiCad, DipTrace, Altium / OrCAD • LTspice, Proteus

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.
