I am an embedded software developer and hardware designer with 6+ years of professional experience to lead your project to the best level. I provide optimal solutions for both hardware and firmware development, also provide prototypes and the small-scale production of designed hardware. I have expertise in the development of - ► Arduino-based hardware design and firmware development. ► ESP32 and 8266 based hardware & firmware design. ► Esp32 based BLE network, mesh network, ESP NOW mesh development, ► NRF51 based BLE development, ► LORA and LORAWAN based firmware, hardware development and prototype design, ► Chirpstack.TTN server deployment on the local, remote server as well as AWS server. ► AWS +NODE-RED+MQTT+GRAFANA+INFLUX DB-based virtual server deployment and custom UI design. ► The THINGS BOARD deployment on local/remote /AWS server with SSH. ► STM32 - ARM-based firmware development & hardware design and prototype manufacturing. ► Raspberry Pi based custom MQTT web server with custom UI design ► Complete Prototype development with small-scale production capabilities. My hardware design includes a Printed circuit board design with customized requirements. I provide complete PCB layout design, prototype PCB board manufacturing, testing of PCB board with advanced tools, and on-demand I provide small-scale production of the hardware /PCB. Price will be negotiable on hardware design and development. My PCB design features include - ► Multilayer PCB design. ► Both rigid and rigid-flex design. ► Provide BOM with the most available component list. ► Provide Gerber and ECAD files for manufacturing. ► Support prototype and small-scale production (PCB). My last project is " LORAWAN BASED ENERGY METER EXTENSION", where I have to measure the Phase voltage, Line voltage, phase current, Line current, Total energy, power factor and send them to the TTN server using LORAWAN based prototype node device and Dragino gateway. The device was successfully worked and installed in the industry environment. You can see details of its working in my portfolio. My goal is to provide the best quality services at an affordable price within a reasonable timeframe. Please visit my website for more details - www. bit-plexlab.com

I build things that exist in the physical world — embedded systems, robotic mechanisms, IoT devices, and hardware prototypes that go from sketch to functional product. With hands-on experience across ESP32, Raspberry Pi, Arduino, STM32, and RTOS-based systems, I work the full hardware stack: firmware, sensor integration, CAD enclosure design in Fusion 360, FDM 3D printing, and PCB layout. I've shipped across domains — rehabilitation robotics, predictive maintenance, food safety sensing, animatronics, and industrial IoT. Currently a Product R&D Intern at Xibotix (building rehab devices and animatronic systems) and previously at Dotworld Technologies, where I delivered real-time actuator control systems end-to-end — from firmware to deployment. I work best with startups that have an idea but need someone who can build it. I don't just write code — I think about the enclosure, the power architecture, the sensor placement, and what failure looks like at 3 AM. That's the difference between a demo and a product.
