I develop production-ready embedded systems and desktop tools,from IoT devices to industrial automation. Core capabilities: - Embedded firmware in modern C & C++ (ARM, STM32, RTOS, bootloaders, communication stacks) - PCB design and testing (multi-layer boards) - Qt/C++ cross-platform applications (configuration, monitoring, diagnostics) - Protocol implementation: CAN, Modbus, MQTT, I2C, SPI, TCP/IP - Technical documentation and testing frameworks Deployed: 100+ production devices, industrial systems, distributed platforms. Production-quality work. Clean code, tested designs, complete docs.

I’m an Electrical Engineer specializing in hardware design and embedded systems for real, production-ready products, not academic or hobby boards. I design and review schematics and multi-layer PCBs (up to 6 layers) with strong attention to power integrity, decoupling, grounding, signal routing, and EMI-aware layout. I routinely validate footprints, part mapping, and BOMs, and prepare manufacturer-ready deliverables for services like JLCPCB and PCBWay. Beyond layout, I focus on design robustness: 1. Proper power architecture and protection 2. Test points, jumpers, and labeling for bring-up and debugging 3. Layout improvements for reliability and maintainability 4. Fixing existing designs that fail in real hardware On the embedded side, I deliver robust, bug-free firmware for ESP32 and STM32, tested under real operating conditions, not just ideal lab setups. I build custom, reusable libraries and drivers so the firmware is maintainable, scalable, and reliable over time. If you need a hardware engineer who can review, fix, or redesign your PCB so it works in production, not just “passes DRC,” I’m the right fit.

$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. I enjoyed working with Malik and would gladly work with him again on future projects." (5.0 ⭐) ✅"Great experience working with Malik Maaz. He is really professional and experienced in his field. Would definitely work with him again!" (5.0 ⭐) Building my Upwork presence after 3+ years in corporate embedded systems (Fortune companies under NDA). My goal is simple: I don't just deliver files; I deliver a production-ready product that ensures your hardware performs reliably in the real world. ⚡ What Makes Me Different Integrated Solutions: I deliver hardware and firmware that function as one unit, resulting in 50% fewer prototype iterations and faster market entry. Complete Ownership: You get one engineering partner for the entire stack, eliminating coordination bottlenecks. Production-Ready Quality: Every design undergoes a DFM (Design for Manufacturing) review. I test in my own lab to ensure your hardware is ready to scale before you ever manufacture a single unit. 🔧 What I Build Automotive & OBD-II: Custom OBD-II port PCB designs (e.g., ATSAMC21-based) and advanced steering wheel electronics integration. Industrial & Wired Systems: Custom wired intercoms and communication hardware, including full firmware, enclosure design, and assembly for international deployment. Industrial IoT: Gas safety monitors, agriculture systems, and gateway devices (4G/WiFi/LoRa) designed for long-term stability and field performance.
