Product Development & PCB Design Engineer

Confidentials • Selbstständig

Jun 2020 - Present5 yrs 11 mos

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 am writing to highly recommend Maryam for any PCB design and hardware engineering roles. She recently completed a complex PCB project for me, and her technical expertise, attention to detail, and professional workflow exceeded my expectations. The project involved a high-density control board featuring...

    Unfortunately, I cannot recommend this service based on my experience. The delivery was delayed and contained multiple fundamental issues, including missing connections, incorrect use of ESP32 pins (e.g. input-only pins used for outputs), and critical flaws in the power design (such as a regulator that...

    Once the project started, Maryam's communication was poor. She was provided a detailed functional/non-functional document that she said she read and understood but the results of her work proved otherwise. The first deliverable (late) appeared to be cut and pasted from other work. Her second deliverable...

    Absolutely love the work we are doing here! Couldn't be happier with the design, schematics and gerber file so far. There is definitely a deep understanding of the whole scope of the project. I will be a returning customer as much as possible!
