Yousaf M.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I help companies turn complex electronic product ideas into reliable, manufacturable products. I am an Electrical and Embedded Systems Engineer with 8+ years of hands-on experience in embedded hardware, firmware, PCB design, RF and wireless systems, IoT, power electronics, sensing, low-power design, product validation, and manufacturing support. I also lead an engineering R&D company, where I work with clients from concept through prototype, field testing, troubleshooting, redesign, and production. My experience spans industrial IoT, smart agriculture, environmental monitoring, wireless tracking, gaming hardware, lighting systems, access-control products, consumer electronics, and custom embedded devices for clients across North America, Europe, Australia, and the Middle East. ### Core Expertise • Embedded systems architecture and product development • Schematic design and multilayer PCB layout • Embedded C/C++ firmware development • RF and wireless hardware development • Wi-Fi HaLow / IEEE 802.11ah systems • LoRaWAN and Sub-GHz ISM radios • Wi-Fi, Bluetooth, BLE, RFID, NFC and Z-Wave • LTE / 4G, NB-IoT and cellular connectivity • GNSS / GPS integration • Antenna integration and RF PCB design • RF range optimization and field testing • EMI, grounding and interference troubleshooting • Low-power and battery-operated systems • DC-DC converters and power electronics • Battery charging and power-path management • High-current motor and actuator control • Sensors and mixed-signal electronics • PCB troubleshooting and failure analysis • BOM optimization and component sourcing • Design for Manufacturing and Assembly • Prototype bring-up and production support ### Embedded Hardware & PCB Design I design complete electronic products from system architecture through schematic capture, PCB layout, prototype bring-up and production.
