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.

Top Rated Plus Embedded Hardware & Firmware Engineer with 8+ years of experience building reliable embedded products, IoT systems, and production-ready electronics. I help startups, product teams, and manufacturers take an idea, prototype, or broken design and turn it into a working embedded product that can be tested, manufactured, and scaled. My work connects hardware, firmware, and real-world product execution. Instead of treating the circuit, code, sensors, connectivity, power system, enclosure, and manufacturing process as separate pieces, I help bring them together into one reliable product. WHAT I BUILD • Custom schematic and PCB design for reliable embedded hardware • Embedded firmware development in C/C++ for real-world products • ESP32, STM32, Nordic, Arduino, Raspberry Pi, and Embedded Linux platforms • BLE, Wi-Fi, LTE, Cat-M1, NB-IoT, LoRa, NFC, GPS/GNSS, and sensor integration • Low-power electronics, battery-powered devices, BMS, and power management • Industrial interfaces including UART, SPI, I2C, RS-485, CAN, Modbus, ADC/DAC, and GPIO • Board bring-up, debugging, firmware validation, and hardware troubleshooting • BOM preparation, Gerber files, assembly files, DFM review, and manufacturing support I have worked across wireless IoT devices, wearable and medical electronics, industrial monitoring systems, automation hardware, smart sensors, connected consumer products, and custom embedded controllers. WHY ONE TECHNICAL OWNER Clients usually come to me when they need more than a schematic or a firmware file. They need someone who can understand the complete system, identify risks early, solve hardware and firmware integration issues, and move the product closer to production. I also lead a full-service engineering team when projects require additional support across mechanical enclosure design, cloud integration, mobile app development, product design, or manufacturing coordination. This gives clients one technical owner while keeping the embedded hardware and firmware work technically grounded.

What I can do for you: • Schematic capture and PCB layout in Altium Designer, KiCad, or EasyEDA, designed for manufacturability from the first revision • Firmware development in C/C++ for STM32, ESP32-S3, and nRF52/53, bare metal or RTOS • Wireless design: LoRaWAN, NB-IoT, BLE, UWB, and sub-GHz RF with custom antenna matching • Battery life optimization for devices that need to run for years, not months • Prototype bring-up, testing, certification support, and transition to volume production If you have a product idea or an existing design that needs to move forward, send me a brief description and I will tell you exactly how I can help.

I design and build connected hardware — schematic, PCB layout, and firmware — with a focus on IoT, GPS tracking, motor control, and wireless products. ━━━━━━━━━━━━━━━━━━━━ RECENT WORK ▸ Wearable GPS rescue tracker — ESP32-S3 + SIM7670G (LTE Cat 1 with integrated GNSS). Full schematic, PCB, BOM, and firmware. Under USPTO provisional patent. ▸ Audio subsystem around SIMCom A7670G for a call-capable device — class-D amplification, MEMS microphone selection, end-to-end schematic and layout. ▸ Custom motor control PCBs — RP2350A + IR2104 + N-MOSFET H-bridge, with PIO-based complementary PWM and current sensing. ▸ ESP32 power-gating circuit with fingerprint-activated load switching. ━━━━━━━━━━━━━━━━━━━━ WHAT I DO WELL ▸Cellular & wireless integration LTE (SIMCom A7670G / SIM7670G), GNSS, BLE 5.0, LoRa, Wi-Fi — including the messy parts: power sequencing, antenna placement, audio paths, and certification considerations. ▸PCB design end to end KiCad, EasyEDA, Altium. Schematic capture through DFM-aware layout, BOM, fabrication files, and rework. Comfortable with multi-layer boards, RF routing, and tight power budgets. ▸Firmware that ships C/C++, Arduino, MicroPython, CircuitPython. I write firmware that's still debuggable six months later — not just the demo that works on my desk. ▸Hardware/software integration The bugs that live between the schematic and the code are usually mine to fix either way, so I'd rather own both sides from the start. ━━━━━━━━━━━━━━━━━━━━ BACKGROUND BSEE from IIUI (Islamabad). Freelancing since 2022 across embedded systems, PCB design, and IoT product development. Flexible on working hours — comfortable with US, EU, and APAC schedules. ━━━━━━━━━━━━━━━━━━━━ If you're building a hardware product and want one person who can take it from a napkin sketch through working prototype — schematic, PCB, firmware — send me the brief.
