Hire the Best Embedded Systems Engineers
in Turkey

I’m an Electrical & Electronics Engineer based in Istanbul. I work across industrial automation and product development, so I can help whether you need reliable control logic. PCB for a device, or a technical analysis/report. What I do best (and how I work): - PLC/HMI automation: Ladder logic, interlocks, alarms, timers/counters, start/stop logic, safe reset flows, and clean operator HMI screens. - PCB design (Altium): 2-layer and 4-layer+ boards, schematic design, component selection, layout with real manufacturing constraints, and clear fabrication outputs (Gerbers/BOM). - IoT & prototyping: Turning an idea into a working prototype—sensors + MCU + power + enclosure planning. I also use CAD tools to design enclosures around the PCB when needed. - MATLAB engineering support: circuit analysis, signal processing basics, simulations, and clear technical documentation. !!!! I’m setting a low introductory rate for my first Upwork contracts while I build reviews—my focus is clean documentation, fast communication, and reliable delivery. Help me build reviews please !!! I’m straightforward: I won’t pretend I know something I don’t. If your job needs research or learning, I’ll tell you upfront and give a clear plan. I care a lot about clean documentation, readable designs, and communication, so you can maintain the project after delivery. If you share your requirements (process description / IO list for PLC, or block diagram + constraints for hardware), I’ll respond with a clear plan, timeline, and what I need from you to start.
