Hire the Best Computer Hardware Designers
in Pakistan

I help startups and founders turn hardware ideas into working prototypes and production-ready products. My work covers embedded systems, PCB design, IoT devices, wearable prototypes, firmware, testing, and manufacturing files. I am a Top Rated Plus Industrial Designer and Electronics Engineer with 7+ years of experience, specialising in end-to-end product development from concept to production. My expertise covers PCB design, embedded systems, IoT development, wearable device development, firmware, enclosure design, prototyping, testing, and manufacturing support. I work with platforms such as STM32, ESP32, nRF, Raspberry Pi, and custom embedded hardware to develop reliable and scalable smart products. What I can help you with: • Schematic design and PCB layout • Embedded firmware development • ESP32, STM32, nRF, Arduino, Raspberry Pi-based systems • IoT devices with BLE, Wi-Fi, GPS, LTE, and sensors • Wearable electronics and compact product prototypes • Battery-powered and low-power hardware design • Prototype testing, debugging, and improvement • Gerber, BOM, CPL, STEP files, and manufacturing support What makes my work different is my complete product development approach. I do not only design a PCB or enclosure separately. I consider electronics, firmware, mechanical fit, compact wearable form factors, component availability, assembly, testing, DFM, and production requirements from the beginning. This helps reduce redesigns, avoid manufacturing issues, and create products that are practical for real-world use and mass production. I have worked with international clients on IoT devices, wearable electronics, health monitoring wearables, industrial systems, sensor-based products, smart consumer devices, medical/health monitoring prototypes, and custom embedded hardware. If you are looking for a reliable engineering partner who can take your idea from concept to working prototype and production-ready product, I can help you build it with a professional, practical, and manufacturing-focused approach.
