I’m a dedicated PCB layout engineer with 7+ years of hands-on experience turning complex schematics into production-ready boards especially in power-hungry and noise-sensitive applications. High-efficiency SMPS designs (buck/boost converters, GaN/SiC integrations) and mixed analog/digital circuits, like ADC/op-amp interfaces for sensors and IoT prototypes. I’ve routed dozens of boards where EMI control and thermal management aren’t just checkboxes—they’re what keeps your device reliable from prototype to pilot run.

Drawing from a rich background in goldsmithing, I embarked on my journey as an apprentice, mastering the intricacies of craftsmanship from the ground up. It was during this formative period that I first encountered CAD software, specifically Rhino3D, which revolutionized my approach to jewelry design. The transition from traditional techniques to digital platforms opened up a world of possibilities, igniting my passion for 3D modeling. Driven by a relentless curiosity, I delved deeper into the realm of digital design, pursuing additional training in 3D modeling techniques and discovering the transformative power of poly-modeling with 3DS Max and rendering with Vray. This newfound knowledge empowered me to not only design jewelry for 3D printing and casting but also to expand my horizons into product design. With a blend of traditional craftsmanship and cutting-edge technology, I seamlessly integrated CAD into my workflow, leveraging its capabilities to craft intricate designs and generate photorealistic renders. Recognizing the untapped potential of my skills, I transitioned into offering my services as a 3D designer, specializing in designing and rendering jewelry and various products. Today, armed with over 9 years of experience, I continue to channel my passion for design into every project I undertake. I invite you to explore my portfolio, a testament to my journey from apprentice to seasoned 3D artist, and discover the artistry and precision that define my work.
