I am an experienced Embedded Systems and IoT Developer with a strong background in ELECTRONICS and C++ programming, specializing in end-to-end development of automation and connected device solutions. I have hands-on expertise working with a wide range of microcontrollers and platforms including Arduino, ESP32, Nordic (nRF series), PIC, and Atmel (AVR, SAM).
My skill set spans both hardware and software, allowing me to take projects from concept to prototype and production. This includes schematic design, PCB layout and firmware development, and integration of sensors and communication protocols like BLE, Wi-Fi, LoRa, Zigbee, UART, I2C, and SPI.
I focus on building efficient, low-power, and reliable solutions for home automation, industrial control, wireless communication, and IoT applications. Whether it's developing custom firmware, designing PCBs, or creating scalable IoT systems, I deliver high-quality and well-documented results

PCB Designer and Embedded Hardware Engineer with hands-on experience with STM32, ESP32, SAMD21, and ATMEGA architectures and IoT product development, along with firmware development. I design PCBs in KiCad and Altium with full JLCPCB and PCBway production support.
I will turn your ideas into a real, manufacturable product or a hobbyist project by providing professional-level PCB layouts, schematic designs, BOMs, pick-and-place files, and even enclosure STL or STEP files.
Services I provide:
PCB design for ESP32, STM32, ATMEGA, or any ARM-based architecture system
Schematic design and multilayer PCB layout in Altium and KiCad
IoT hardware design with sensors, power management, and connectivity
Design for manufacturing and JLCPCB- and PCBway-ready Gerbers
Hardware debugging and prototype improvement
PCB review services
Enclosure design in FUSION360
I focus on practical engineering, not just producing design files. My goal is to deliver PCBs that work reliably in real hardware, are easy to manufacture, and are optimized for cost, performance, and long-term reliability. Whether you're building an IoT device, embedded system, or custom electronic product, I can help take your idea from concept to a production-ready prototype efficiently.

I am electronics engineer and have build more than hundred electronics boards, most of which have been commercial products.
I will take you idea and transform it into real world product. All I need is some basic specification and intended application and then I can create a high level design document which will translate into properly annotated schematics and production-ready, cost optimised PCB design.
