Fasih Ullah SaleemRobotics Engineer

Robotics Engineer | Embedded Control | STM32 / ESP32 | Real-Time Systems

I build autonomous and remotely controlled systems on STM32 and ESP32 with real-time firmware, sensor fusion (GPS, IMU), motor and PWM control, feedback control and wireless communication, with full hardware-software integration from custom PCBs and power management to cloud and web monitoring. Electrical Engineering graduate (CGPA 3.79/4.00, PEC registered) comfortable owning robotic systems from concept to deployment.

In the stack

Where a robotics engineer sits in a connected product.

The solid layers are the ones this role owns: hardware & pcb, firmware, network & iot. The faded ones are the rest of the system I also build, so nothing is designed in isolation.

  • Four-wheeled robotics vehicle with stacked microcontroller boards, motor driver and an ultrasonic sensor

    Embedded control

    A robotic vehicle controlled over Wi-Fi, pairing an STM32 for real-time motor and sensor control with an ESP32 handling wireless communication. It supports both a manual remote-drive mode and an autonomous navigation mode, showcasing tight coupling between a wireless link and an embedded control loop.

  • Custom four-layer PCB for the fleet tracker on a cutting mat, with GPS patch antenna, GSM module and screw terminals

    Lead: firmware, PCB and integration

    An end-to-end fleet telematics system built on a custom STM32F427 board. The device reads GPS position and MPU6050 motion data in real time, detects accidents and rollovers, and streams everything over a SIM800L GSM link to a web dashboard. A full power subsystem handles automatic switching between the vehicle battery and an onboard backup, with charging and protection circuitry, so the unit stays online even if main power is cut.

  • Automated bottle filling rig with a stainless nozzle, inline flow sensor, diaphragm pump and keypad control enclosure

    Control systems

    An automated bottle-filling station governed by closed-loop feedback. Flow sensors meter each pour, a keypad and display provide the operator interface, and the control logic drives the pump to hit target volumes reliably: a compact demonstration of industrial process automation.

    Power electronics

    A bidirectional buck/boost converter driven by STM32-generated PWM. I implemented the control firmware, then tested and tuned the converter across operating points, measuring regulation, ripple, and efficiency to validate the design under real load.

Questions

What people ask before hiring a robotics engineer.

What robotic systems have you built?

A Wi-Fi controlled autonomous vehicle pairing an STM32 for real-time motor and sensor control with an ESP32 for the wireless link, with manual and autonomous navigation modes; a fleet tracker fusing GPS and an MPU6050 IMU for accident and rollover detection; and a feedback-controlled industrial filling system.

Do you handle the electronics and power as well as the control firmware?

Yes, custom PCB design, motor driver stages, battery monitoring, automatic main/backup power switching, and a buck/boost converter with STM32-generated PWM control that I designed, tuned and measured on the bench.

Can you build a robot prototype for a hobby project or a research group?

Yes. I take freelance robot builds of any size, from a hobby rover to a research platform, and open to remote and on-site roles worldwide for robotics and embedded-control teams.

How do you approach autonomous navigation on a microcontroller?

Deterministic real-time loops: interrupt-driven sensor reads, a fixed-rate control loop, PWM to the drivers, and the wireless link kept on a separate core or MCU so a dropped packet never stalls the control loop.
