I’m an electronics and product development engineer specialising in taking hardware ideas from concept through to working prototypes and production-ready designs. My work spans the full product development stack, including schematic capture, PCB layout, embedded firmware, IoT system architecture, and enclosure design (3D CAD and printing). This means clients can work with a single engineer rather than coordinating multiple freelancers, although I have a team of engineers across various disciplines for additional resources if required. Before founding my own consultancy, ZTPrototypes, I worked as an electronics engineer across multiple IoT consultancies, a large product development firm, and a company specialising in environmental sensing devices. Since then, I’ve delivered projects across the industrial, consumer, and IoT sectors, often under tight timelines and evolving requirements. I also design with real-world constraints in mind, such as manufacturability, power consumption, enclosure integration, and regulatory considerations, rather than just getting something to work on the bench. I have experience taking multiple products through compliance tests at accredited test houses to ensure compliance with various global regions, including CE, UKCA and FCC marking. If you’re looking for someone who can move quickly, communicate clearly, and turn an idea into a working, testable product, feel free to get in touch and we can discuss your project. Feel free to have a look at my portfolio below in the meantime.

As an experienced Avionics/Electronics Engineer, I bring a diverse skill set and 4+ years of expertise in electronics and circuit verification, hardware implementation using Verilog, Digital Signal Processing.

I have honed my skills in working with Software Defined Radios and Direct RF generation using Xilinx (RFSOCs, Zynq paired with AD9361) and NI hardware (FlexRIO, CRIO, USRP, myRIO). Over the past three years, I have developed my capabilities as a LabVIEW/MATLAB developer, working with High Speed Data acquisition, and implementing Digital Signal Processing (DSP) chains and algorithms. In addition to my technical skills, I am committed to ensuring timely delivery of projects and maintaining open and clear communication with clients throughout the project tenure. My goal is to provide innovative solutions that meet the needs of my clients and contribute to the advancement of the industry. I am always open to new challenges and learning opportunities.
