    I'm fully trained in current electrical engineering practices. I've been doing electronics work for the last couple of years. I specialize in embedded systems; specifically IoT products. I have taken a product from ideation to production including embedded system design, embedded system programming, 3D enclosure modeling and DFM (design for manufacturing). I have worked with manufacturers to make products more robust, cheaper and faster to produce. I work with a lot of startups so I understand the space; tight budget, fast turn-around times & a lot of uncertainty. I can forecast project requirements, timelines and budgets as I've done in the past. ------------------------------------------------------------------------------------------------------ Electronics Experience: low power battery operated devices, microcontrollers, high power switching controls, analog circuits, wireless/bluetooth design, high power LED, product security (encryption), embedded programming C/C++ and peripheral microchip driver creation. I have a lot of experience with non-OS based and lightweight RTOS firmware. ------------------------------------------------------------------------------------------------------ Industrial Design: 3D modeling of enclosures including snaps & press fits, DFM, subassembly design, wire harnesses, low and high volume manufacturing processes (injection molding, resin casting, etc), material I have knowledge of certifications (FCC, UL, CE). ------------------------------------------------------------------------------------------------------ Medical Device In my previous career I did cancer research for 5 years. I am well versed in biological systems, biological tests, testing equipment and non-patient based equipment. I've published multiple peer reviewed papers in this area.

    I have over 22 years of experience working and consulting for tech companies in Silicon Valley. Every technical challenge that I had overcome assured me that with the right frame of mind, I could accomplish anything. Engineering is also my hobby, and I have been doing it since before high school. I was born with a soldering iron in one hand and writing code with the other. I designed the hardware for over 100 projects, most of them being sold today. Some notable ones are Snapchat Spectacles (designed most of the electronics and PCB layout), Thornwave Labs' Bluetooth DC Power Meter (PowerMon) and all the other projects on the webpage, various RF modules (RN-171, RN4020, RN52), and development boards designed while working at Microchip. I also created production testers, lots of C/C++ programming, and firmware design. What I can do for you? --------------------------- High Level: project management, research. I am very experienced with hardware design and firmware, which allows me to integrate them more efficiently. Hardware: circuit design, component selection, electrical schematic, PCB payout. I am using Altium Designer. I will provide you with everything you need to go to manufacturing: Gerber files, NC drill, pick and place, assembly diagrams, 3D prints, 3D STEP model, and electrical schematics as well as offer support after the project is completed. I have experience with analog and digital design, RF, high-speed design, microcontrollers, highly complex boards, LCDs. I can run Spice simulations as well. I worked with various technologies and protocols: SPI, I2C, UART, USB, CAN, RS-485, Ethernet, Bluetooth, WiFi, and so on. Prototyping: I will manufacture the prototypes at a much lower cost than average. Over the years, I have developed working relationships with manufacturers in China, hence the cost-saving. I also have a lot of equipment: multimeters, oscilloscope, logic analyzer, vector network analyzer, USB protocol analyzer, power supplies, digital electronic load, soldering equipment, computers, and so on... Certifications: I can assist and oversee the certification process for FCC, IC, and others. Firmware development: I have 24+ years of experience coding in C/C++ and 20 years of firmware development. I can architect and develop your firmware from the ground up. I am exceptionally versed in the ARM Cortex line of microcontrollers: STM32 and Nordic. I will provide you with production-quality firmware. I know the ST and the Nordic microcontrollers like the back of my hand. I can get firmware done very quickly and efficiently for these chips. Software development: Basic tools running in Linux/Windows/Mac, basic GUIs. I can develop all the software tools you need for debugging, testing, and manufacturing. Manufacturing: If your project reaches this phase, I can offer contract manufacturing services. I will be delivering your finished product, ready to sell. The rate I displayed is an average number. It can vary up or down based on the complexity of the project. My rate reflects the experience and knowledge I have. I am good at what I do. Also, keep in mind that I will not bill you for hours like lawyers do for the time they spend in the shower thinking about the project. I will bill you only for the hours I spend advancing the project in a meaningful way.

    For the last 20 years, I have designed many electronics projects involving defining requirements, system architecture, part selection, schematic design, PCB layout, and firmware/software programming. Designing electronics and embedded systems can be extremely complicated. Unfortunately, it can be difficult to communicate clearly even about simple topics. One of my greatest emphases is effective and honest communication. This always requires careful listening and sometimes the willingness to say "I don't understand. Will you please explain this to me?" and the honesty to say, when necessary, "I don't know, but let me go figure out the answer." I live to face new challenges, solve new problems, and learn new things. Let me bring my experience and enthusiasm to bear on your project.

    Embedded Hardware Design Engineer with more than 12 years' experience in the field of circuit design and embedded systems. I have been working on Upwork since July 2020 and now a “top-rated” Embedded Developer. Here’s a recent client review: "Zahoor understood my problem easily and did a careful analysis of my firmware - despite it being poorly commented and complex. He really went above and beyond for this contract and I was really impressed with his skills and professionalism. If you are lucky enough to have Zahoor bid on your project, just select him, you will not be disappointed." I want you to know that your success is at the very core of my endeavor. And that you’ll be entrusting your product to a developer who is capable and willing to go the extra mile. More importantly, I’m a developer who stands by his word. I will offer unlimited revisions until you’re absolutely satisfied. You can invite me for a discussion about your product and I’d love to learn more about your product.
