Sohaib Q.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 am an enthusiastic, hands-on engineering professional with a proven track record of more than 14+ years in Embedded Systems, Electronics, Power Electronics, and POE-based systems. I have worked on micro-controllers starting from the Atmel 8051 and PIC18, and I have gone through complex systems like PIC32, ARM Cortex-M3, AVR Arduino and STM8 & STM32, etc. I delicately follow the design from concept sketching to bringing up the PCB boards and mechanical enclosures. I enjoy reading about technological developments and adapting to the changes to maintain my skills aligned with industrial standards. 1.
