Hire the Best ESP32 Freelancers
in Pakistan

Is your ESP32, Arduino, or motor control project stuck, buggy, or still just an idea? I can help you get it built and working. I'm a mechatronics and control engineering student who works across the full stack: firmware, sensors, motor drivers, and the control logic tying it together, not just code in isolation. What I've built: Migrated a legacy Arduino Mega 3D printer to ESP32-S3, added a custom web control interface, and upgraded the motor driver from A4988 to DRV8825 Designed and built a palm-sized quadcopter from scratch, including a custom PCB in EasyEDA Built a GUI-controlled robotic arm with real-time motion control Implemented a PID-controlled closed-loop temperature system Built a sensor-based fault detection system for scaled bridge models Also built: a line-following robot, maze-solver, obstacle-avoidance robot, WiFi-controlled RC car, logic-gate digital clock, and a DC power supply I also ran ROBOQUEST 2.0, a university robotics competition with 300+ participants, so I'm used to firm deadlines and explaining technical work clearly to people who aren't engineers. Tell me what you're building, what's broken, and what the finished system needs to do. I'll give you a straight answer on whether it's a quick fix or a bigger build.

If you're looking for an engineer who can design hardware, develop firmware, integrate AI, and build complete embedded products, I'd be happy to discuss your project and help bring your idea to life.

Embedded systems engineer and hardware designer with 10+ years turning product ideas into manufactured electronics, from schematic and multilayer PCB design in Altium to firmware on STM32, nRF52, ESP32, and FPGA/Zynq platforms. I build wireless and IoT products using BLE, LoRa, and Zigbee, and I've delivered hardware for industrial, automotive, medical, and aviation-grade applications, including ATEX/explosive-zone rated designs. I have taken two of my own product designs from prototype through to full production runs. One scaled to 1,000+ units and another to 100+ units, with me handling everything from board design to manufacturing coordination along the way. 𝗪𝗵𝗮𝘁 𝗜 𝗱𝗲𝗹𝗶𝘃𝗲𝗿 𝗲𝗻𝗱-𝘁𝗼-𝗲𝗻𝗱: System architecture and component selection, schematic and PCB layout/routing (up to 10 layers, mixed-signal and high-speed interfaces), prototyping and validation of boards with hundreds of SMD components, and embedded firmware/driver development in C/C++ and Verilog running on FreeRTOS, Zephyr, and other RTOS. I also support feasibility studies, cost estimation, and turnkey manufacturing coordination with PCB fabs, suppliers, and test labs, plus PCB reverse engineering and reviving obsolete hardware. 𝗠𝗖𝗨/𝗦𝗼𝗖 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲: STM32, Nordic nRF52/nRF9160, TI wireless MCUs, ESP32, Renesas, and Xilinx/Altera FPGA/CPLD/Zynq SoC. If you need a hardware or firmware partner who can take a project from concept through certified, manufacturable product, let's talk about what you're building.

50+ hardware and embedded systems projects delivered, from concept through manufacturing. Full project lifecycle ownership: requirements → schematic → PCB layout → firmware → prototyping → testing → DFM/production handoff. Projects spanning industrial electronics, IoT devices, RF systems, wearables, and battery-powered products. I design and build hardware products that survive real-world contact — not just designs that work in simulation. For 6+ years, I've taken products from a blank schematic to manufactured, field-deployed hardware: industrial electronics, IoT devices, RF systems, and embedded platforms used in real industrial and consumer environments. I work across the full stack — system architecture, PCB layout, firmware, prototyping, and DFM — so you get one engineer who understands how a firmware design decision affects the PCB, and vice versa. If you need someone who can own a hardware product end-to-end, or step into a specific phase (schematic review, firmware bring-up, RF tuning, manufacturing prep), I can help. WHERE I ADD THE MOST VALUE Custom PCB design, 2–12 layers, including high-speed digital and RF layouts EMI/EMC-aware design and Design for Manufacturing (DFM) Embedded firmware in C/C++ for ESP32, STM32, nRF52/nRF53, RP2040, and ARM Cortex-M platforms IoT connectivity: Wi-Fi, BLE, LoRa, GSM/LTE, GPS/GNSS, cloud-connected devices Industrial communication: UART, SPI, I²C, RS485, Modbus, CAN Bus Power electronics: battery management systems (BMS), DC-DC converters, SOC/SOH estimation, industrial power monitoring Prototype-to-production support, including BOM creation and manufacturing handoff RECENT WORK Industrial gas metering system (EVC V5) — redesigned the hardware architecture with RS485, CAN Bus, and Modbus communication, built to meet EMI/ESD protection and hazardous-environment requirements. Ground Penetrating Radar — designed a 100–900 MHz subsurface sensing system built around a high-efficiency Class-E RF power amplifier and custom embedded electronics. EEG smart glasses — developed wearable electronics for brainwave acquisition, signal conditioning, embedded processing, and wireless transmission. Dual-MCU wireless audio platform — low-power architecture combining nRF5340 and ESP32-S3, with BLE, Wi-Fi, secure storage, and advanced power management. Energy monitoring & battery management platform — multi-source monitoring across AC power, solar generation, and battery storage, with SOC/SOH estimation, GSM connectivity, Ethernet, and remote monitoring. High-power RF amplifier — 100 MHz Class-E design delivering up to 1 kW output. Multiple ESP32-based industrial and consumer products — automation, environmental monitoring, sensing, and data acquisition. Aero-Guide robot — autonomous, AI-assisted navigation platform, finalist in a national engineering competition. WHAT YOU GET WORKING WITH ME Clear technical communication from day one — I'll tell you early if something won't scale, won't pass EMC, or won't be manufacturable, rather than letting you find out after fabrication. Deliverables built for handoff: schematics, PCB layouts, Gerbers, BOMs, manufacturing files, firmware, and documentation — organized so another engineer (or your future self) can pick them up. Fast, practical problem-solving when prototypes don't behave as expected. A focus on shipping reliable, buildable hardware — not just a working bench demo. Outside of engineering, I spend time mountain trekking, with expeditions to several major peaks in Pakistan, including base camps of multiple 8,000m mountains. It's where I keep my planning and problem-solving instincts sharp under pressure — skills that translate directly into debugging hardware at 2 am before a deadline. If you have a hardware or firmware challenge — from a rough concept to a stalled prototype that needs fixing — I'd be glad to take a look and tell you honestly what it'll take to get it done right.
