If it blinks, moves, or talks to the cloud I've probably built it. I’m an Embedded Systems Engineer and PCB Design Specialist with hands on experience turning complex ideas into realworld prototypes. Whether it's IoT devices, automation systems, or smart hardware, I design the circuits, write the firmware, and build the boards all under one roof. From the first spark of an idea to a fully functional, connected prototype, I help startups, makers, and engineers bring hardware to life. What I Do Best: PCB Design using EasyEDA Pro, KiCad, and Altium Microcontroller Programming for ESP32, Arduino (Nano, Uno, Mega), and Raspberry Pi 4B / CM4 Hardware Prototyping from schematic to soldered and tested boards IoT Integration using WiFi, BLE, MQTT, HTTP, and sensor data collection Writing clean, efficient code using Arduino IDE and Thonny I Specialize In: Rapid prototyping for smart devices Sensor interfacing and real-time control Low power and compact PCB solutions IoT product development with cloud connectivity Why Clients Hire Me: End to end development (design + code + prototype) Clear communication and milestone tracking Fast turnaround without sacrificing quality I treat every project like my own product Let’s build something smart, fast, and powerful — together.
