Muhammad U.

I am an Electronics Engineer specializing in end-to-end product development from concept to production. With over 4 years+ of experience in PCB design, embedded systems, and IoT solutions, I have delivered reliable, scalable, and manufacturable products using platforms such as STM32, ESP32, nRF, and Raspberry Pi. My work is strongly grounded in Design for Manufacturing (DFM), ensuring a smooth transition from prototype to mass production. I provide complete product development, including fully functional prototypes, assembled hardware, and production-ready physical products delivering solutions that are ready for real-world deployment and manufacturing. **Core Expertise** * Digital & Analog Circuit Design * Embedded Systems & IoT Development (STM32, ESP32, nRF, Raspberry Pi) * Wireless Communication & IoT Protocols * Power Supply & FPGA Design * Multilayer PCB Design (DFM/DFT compliant) * PCBA support, component sourcing & manufacturing files (BOM, Gerber, CPL) **Tools & Technologies** * EDA: Altium Designer, KiCad, EasyEDA, Eagle, MATLAB * CAD: SolidWorks, Fusion 360, AutoCAD, CREO * Simulation: Proteus **Product Design Services** * 3D Design, Rendering & Enclosure Development * Rapid Prototyping (including 3D printing) * Complete hardware + IoT product development from idea to working prototype **What You Get** * Fully tested, production-ready PCB designs * Cost-effective and optimized solutions * Clean, professional documentation for manufacturing * Production ready prototypes and mass production ready products. * Physical assembly products at your door step. **Key Strengths** * Strong experience in integrated **electronics + mechanical + IoT systems** * Custom module development (no reliance on off-the-shelf boards) * Fully equipped hardware lab for prototyping and testing * Experience working with international clients I’m available to support your project at any stage. If you’re looking for a reliable engineering partner to transform your idea into a smart, connected, and production-ready product, I’m ready to deliver. 📺 YouTube: Rajj Engineering 💼 LinkedIn: Muhammad Usman Rajj 🏭Company : ZamZamTronic Let’s build something amazing together.
