Jun 2020 - Present6 yrs 1 mo

Working as an Independent Product Development & PCB Design Engineer, delivering complete electronic product solutions from initial concept through prototyping and manufacturing readiness. My core expertise includes professional multi-layer PCB design, hardware prototyping, functional testing, and preparation of fully documented, production-ready manufacturing files. I design optimized PCB layouts with proper grounding strategies, signal integrity control, power distribution planning, thermal considerations, and EMI-aware routing to ensure long-term reliability and stable performance. I provide complete hardware development services including: • System architecture definition and hardware block diagram creation • Analog and digital circuit design • Schematic capture and component selection based on availability and cost optimization • Multi-layer PCB layout design with DFM and DFA considerations • Power management, battery systems, and protection circuit design • Hardware prototyping, debugging, and validation testing • Embedded firmware development for ESP32, STM32, Raspberry Pi, and other microcontrollers • Integration of communication protocols (UART, I2C, SPI, CAN, RS485, Modbus, MQTT, HTTP, WiFi, BLE) • Sensor, actuator, wireless, and industrial interface integration • Preparation of complete manufacturing documentation (Gerber files, drill files, BOM, pick-and-place files, assembly drawings, fabrication notes) • Product enclosure design support, mechanical integration, and PCB-enclosure alignment for real-world deployment I collaborate directly with startup founders and engineering teams to transform product concepts into reliable, scalable, and manufacturing-ready electronic systems. My focus is delivering technically robust, cost-efficient, and production-optimized hardware solutions ready for commercialization. Delivered multiple functional prototypes and production-ready PCB designs for IoT, automation, and embedded hardware applications.

    I chose Maryam to undertake my project because she struck me as a very capable and talented engineer, and she has proven that is true. My correspondence has not been with Maryam directly, and I understand that culturally a woman can't talk to a man, but having a go between has made "attention to detail"...

    Maryam was great! I needed a PCB for a project and I have 0 experience building small electronics. I gave her a description of what I wanted and was nervous I did not explain well enough due to my little knowledge, but she delivered exactly what I was looking for! She was fast to respond and answered...

    I had a really good experience working with him on my hardware project. I originally came in with just an idea, some rough requirements, and a general concept of what I wanted to build, and he helped turn it into a real working prototype step by step. He handled everything from the schematic design and...
