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.

I also work with Keil uVision, Arduino IDE, PlatformIO, and VS Code. IoT Solutions: I design complete IoT hardware solutions, including sensor integration, wireless communication (WiFi, Bluetooth, LoRa), and power management. Prototyping & Testing: I can assemble and test your prototype, providing you with a working proof of concept. I also offer debugging and troubleshooting services. Documentation: I provide comprehensive documentation, including schematics, layout files (Gerber, BOM), firmware source code, and user manuals. My Process My approach is client-centric. I believe in clear communication and transparency throughout the project. Here's how I work: Discovery Phase: I start by understanding your project requirements, goals, and budget. I ask detailed questions to ensure I have a clear picture of what you need. Proposal: I provide you with a detailed proposal including scope, timeline, and cost. Design & Development: I work on the design, keeping you updated with regular progress reports and seeking your feedback at key milestones. Review & Revisions: I deliver the initial design for your review. I offer revisions until you are completely satisfied. Delivery: I deliver all final files in your preferred format. Why Choose Me Quality: I am committed to delivering high-quality, reliable designs. Communication: I speak fluent English and provide regular updates. No communication gaps. Deadlines: I respect your time and deliver on schedule. Value for Money: I offer competitive rates without compromising on quality. Client Satisfaction: Your satisfaction is my top priority. I offer unlimited revisions. Industries I Serve I have worked on projects in various domains, including consumer electronics, medical devices, industrial automation, IoT, automotive, and wearable technology. Let's Work Together I am excited about the opportunity to work on your project. Whether you have a clear vision or need guidance to refine your idea, I am here to help. Let's schedule a call to discuss your project. I look forward to collaborating with you!

I am a Computer Engineering Undergraduate with experience in Autodesk Fusion 360, 3D Printing, Programming in C/C++ for microcontrollers using the Arduino framework, and Python as a general-purpose programming language. I have done several projects where I applied my skills to solve problems and/or design solutions. The project I am most proud of to date is my university project, the design of a mechanical system to automate the performance of a puppet show. This is where I designed, 3D printed, and tested mechanical parts that correlate to the system, these include: The main linkage mechanism to operate the puppet with servomotors, parts to use in conjunction with extruded aluminium assemblies for a belt-driven gantry, and other miscellaneous designs for a speaker casing, motor mounts, idler pulley bearing mount, and parts for a belt tensioner mechanism.
