I am an RF and electronics design engineer from Ukraine with strong experience in antenna design, RF PCB layout, and general electronic hardware development. I focus on practical, manufacturable designs with predictable performance. Core expertise: - RF PCB layout (impedance control, grounding, isolation, EMI reduction) - High-speed and mixed-signal PCB design (impedance and length matching) - Schematic & PCB layout and BOM for production-ready hardware - Power supply and filtering design - Antenna design and tuning (GNSS, Wi-Fi, ISM bands...) Typical work: - Wi-Fi, BLE, LoRa, and custom RF hardware - Compact and embedded antennas - Multilayer PCBs optimized for performance and cost - Design review, layout correction, and RF/EMI troubleshooting Tools: - RF design and simulation tools (ADS, CST, and HFSS) - PCB design tools (Altium, KiCAD, OrCAD, PADS, and EasyEDA) - Others (NI Multisim, Proteus, Matlab...) Thanks for visiting my profile.

Custom PCB with Encoder Interface

Excellent response and quality work product. We made a couple of errors on the schematic and Leonid quickly identified and corrected them. We will definitely hire Leonid again.
