I’m a skilled RF and mmWave hardware engineer specializing in antenna and PCB design, with extensive experience in the automotive and wireless industries. My work spans all stages of development - from early concepts and circuit planning to detailed electromagnetic simulation, prototyping, testing, and validation. I use industry standard tools like CST Studio Suite, Ansys HFSS, Altium Designer, KiCad, Altium, SPICE, and FreeCAD for design, simulation, and mechanical integration — making sure each stage of development connects smoothly from concept to realization. In addition, I maintain a small RF lab equipped with a vector network analyzer, spectrum analyzer, oscilloscope, and all other tools needed for soldering and prototyping, allowing me to test and verify designs hands-on. I enjoy tackling projects that combine simulations and practical hardware work. Whether it’s developing antennas, optimizing RF circuits, designing PCBs, or helping with various electronics projects, I aim to create solutions that work reliably in the real world :)

I started my journey in engineering during my university years, where my fascination with RF began. While others were exploring general electronics, I found myself deeply drawn to RF circuits, RF propagation, and RF system behavior. I spent countless hours in labs studying RF fundamentals, experimenting with RF signal generation, RF matching networks, and RF antenna design. My dream was clear early on, to become an expert in RF engineering and build real-world RF systems that solve complex communication challenges. During university, I focused heavily on RF projects, including RF transceivers, RF filters, and RF PCB design. I developed a strong foundation in RF theory, RF simulation tools, and RF measurement techniques using VNAs and spectrum analyzers. My academic projects revolved around RF optimization, RF impedance matching, and RF layout best practices, which shaped my career direction. After graduation, I transitioned into professional RF design, where I have been consistently working on RF systems, RF PCB layouts, and RF product development. My experience includes RF front-end design, RF antenna integration, RF shielding, and RF performance tuning for wireless systems such as WiFi, BLE, LoRa, and cellular IoT. I have hands-on experience in RF debugging, RF compliance considerations, and RF certification readiness (FCC/CE). My approach to RF design is practical and detail-oriented, ensuring RF signal integrity, minimizing RF losses, and optimizing RF performance in real-world environments. I continuously refine my RF skills through simulation, testing, and iteration, always aiming for high-efficiency RF solutions. Today, my goal remains the same as it was in university: to push the boundaries of RF design, create reliable RF systems, and deliver high-performance RF products that meet both technical and commercial requirements.
