WHAT I DO - PCB design: schematic capture, routing, Gerbers, BOM and manufacturing files - Hardware bring-up, testing and validation: sensors, actuators, firmware, communication links - ESP32 and Arduino firmware in C/C++: sensors, WiFi, Bluetooth, MQTT, TCP - 3D CAD: parts, enclosures and cabinets, delivered as native files, STEP and STL - Control systems: PID and fuzzy logic, with experimental validation - Technical documentation: interconnection diagrams, power budgets, test protocols EXPERIENCE At COTECMAR, a naval science and technology corporation, I spent six months on systems integration. I designed the communication architecture combining RS-422, TCP/IP Ethernet and radio modems; modelled the system cabinet in 3D at 1:1 scale, integrating 8 subsystems and migrating it from rack format to a portable enclosure; produced 6 electrical interconnection diagrams adopted as project reference documentation; and ran the laboratory test protocol validating the communication links. SELECTED WORK - SwarMind (final-year team project, 3 authors): a swarm of 10 autonomous robots. I designed the double-sided octagonal PCB through 4 iterations, integrating the ESP32, 8 perimeter infrared sensors, motor control and battery monitoring, replicated across all 10 units. I also ran the experimental validation: in a 2x2 m arena, 7 of the 10 robots converged on the target zone in about one minute. - MiniSumo competition robot: I designed the PCB and the autonomous and Bluetooth control system, and handled testing and validation of the sensors, actuators and control code. Second place, UTBot Robotic People Fest 2023. - Digital viscometer (team project): I produced the wiring diagram, implemented fuzzy-logic temperature control over Peltier cells via PWM, and redesigned the power stage after two thermal failures, converging on a topology with reversing relays and independent PWM regulation per cell. Validated viscosity curve from 25 to 50 C. HOW I WORK I deliver with technical documentation: power budgets, torque and autonomy calculations, design rationale and manufacturing-ready files. I am explicit about what I did personally and what was team work, and if something is not feasible I say so before we start, not at the end. Native Spanish. Certified C1 English (EF SET).

$50K+ wasted on prototypes that don't work. 6-month delays because hardware and firmware teams can't communicate. Product launches missed because "the engineer said it would work."I eliminate these nightmares by owning both sides: PCB design AND firmware development in one engineer. 🎯 Why Hardware Startups Choose MeMost embedded projects fail at the hardware-software integration stage. Teams work in silos. The PCB designer blames the firmware developer. The firmware developer blames the hardware. Your timeline explodes. I'm accountable for both. When I design your PCB, I'm already writing the firmware in my head. When I write your firmware, I know exactly what the hardware can handle. No finger-pointing. No excuses. Just working products. Recent Client Wins: ✅"Great experience from start to finish. They reviewed two PCBs for me, gave clear and useful feedback, and everything went perfectly. Communication was smooth, the work was thorough, and I’d be happy to work with them again" (5.0 ⭐) ✅ "Malik delivered good work on this embedded systems and video tutorial project and I enjoyed working with him. His communication was excellent, he met all deadlines, and the quality of the deliverables was strong. The project involved embedded development together with the creation of clear and professional tutorial content, similar to the style and quality showcased. He handled both the technical and educational aspects effectively. I appreciated his responsiveness, technical skills, and willingness to collaborate throughout the project.
