PCB designer with a background in industrial automation and embedded systems. I specialize in turning client requirements into manufacturable hardware efficiently, whether that's a new design from scratch or a fast, precise fix to something already built. I work independently across the full process: scoping the requirement, schematic design, layout, and staying in clear communication with the client throughout. I'd rather ask a clarifying question upfront than guess and have to redo work later. If you need a board designed or an existing one fixed fast, happy to take a look.

Do you need electrical engineering expertise? Hey there! For those of you who do not know me, my name is Nicholas. I am an Electrical Engineering Consultant, and I have something really important that I want to share with you today. For most of you reading this, hiring an electrical engineering freelancer or contractor has been a struggle to say the least. You have likely lost a great deal of money only to receive a sub-marginal product. Constant change orders, redraws, slow work, missed deadlines, failing “cross-functional” teams, no quality assurance, and huge bills are just a few examples. I would imagine that you are feeling very frustrated, confused, and maybe even a little humiliated. Does this sound about right? You are correct to be worried, because many people get screwed over when they hire an engineering contractor. But what if I told you there is one thing, just one thing you could do to flip the script? It is as easy as sending me a message on Cad Crowd. I am an American entrepreneur, electrical engineer, and trusted consultant. I am an accomplished expert with nearly a decade of experience in the electrical engineering industry. As a knowledgeable professional with experience in the nuclear industry, I have had serious involvement with numerous quality-dependent, critical power and control systems. Within five years of graduating from the prestigious Clarkson University with a Bachelor of Science Degree in Electrical Engineering, in addition to minors in both Computer Science and Mathematics, I obtained experience at a multinational technology company and also rapidly became a trusted, lead analytical engineer at Indian Point Energy Center. Today, I help individuals and entrepreneurs maximize their profits by increasing their technical expertise. Once we are both interested in working together on a project, before you even spend a penny, I offer a free, no-obligation video conference kick-off meeting to eliminate any reasonable doubt that we are a perfect match for each other. When working with me, you get to save money on high-quality services. If, like for many cash-constrained businesses, your budget is under scrutiny, you may be forced to rationalize your procurement model. Traditional consulting firms are just not agile enough to adapt. Red tape strangles engineers in many firms. Do not overspend on a wasteful system. Embrace the cost reductions! It is the only way to accelerate your growth and wealth! When working with me, you have access to a quick, easy, and convenient hiring process. In the engineering services sector, most businesses still rely heavily on localized industry experts, consulting firms, and in-house talent. These engineers are often experts, but their geographic proximity to their clients is more often their greatest fortune. The process for procuring my service is extraordinarily quick and simple. I embrace business flexibility. All you need to do is send me a brief message on Cad Crowd! When working with me, you get clarity and security. The payments involved are clearly defined upfront. You do not assume the risk that a firm might claim to be starting a project, take a deposit, and then not deliver. There is no reason not to act now. Your co-workers will rave about your success! When firms change engineers during the project, team turnover can put projects of any size at risk. Throughout the process, one or more team members leaving could result in a project failing if the knowledge and talent walk out the door. When working with me, you know that I am going to be the one working on your project from start to finish with an outcome driven mindset. Visit the link below now to check out my website and see why businesses come to me for solutions. I want to help you, but I am a busy guy and do not have much time to add additional projects to my plate. Do not wait until it is too late. Do not continue to struggle day to day to ensure your market dominance and make a sustainable profit. Everyone knows that we needed our independent expert opinion and design solutions yesterday. Make your life easier. Send me a message on Cad Crowd now to get your project started! I will talk to you soon.

CHILE: I have started my work experience as a Junior level Android Developer in a job that required image editing and interface design for phones. I also worked on low-level programming (C) for microcontrollers. Communication protocols MODBUS, UART, I2C, ISCP, MIDI. When I gained more experience, I decided to specialize in the EgleCAD program for PCB design for industry and IoT. I have used the EagleCAD program for more than 2 years and I have created libraries of devices and chips that were not found in the standard libraries. I also design from the datasheet taking into consideration the different measurements that the manufacturer has. CAM Gerber DXF BOM PLC PnP files are common in PCB design. I can learn to use other software for projection. Then I learned how to use EasyEDA for fast prototyping PCB designs. To test the PCBs I used a digital oscilloscope. I founded a hardware development company (Gea Tecnologia) to be able to work together with universities. The company worked closely with a team of bioengineers from Adolfo Ibañes University and a private company called DigitalHealt. The project is called Grace and currently has a US patent. The company grew and we had requests for very specific things that required little development time. One of them was to create a device that provided a wireless network to provide Internet connection in extreme places in Chile. They had to be energetically autonomous modules and cheap to build. The company (Statknows) was very happy with the result.(LoRa). ITALY: I applied to Embedded Solutions SRL company which is specialized in the production and manufacturing of electronic boards. Located in Misinto. Here I learned many concepts of production and test techniques (collaudo) for pcbs. A very serious company where every aspect of the design is guaranteed 100% even aesthetically.
