Thank you for taking the time to view my profile!
I am an electrical engineer with experience in PCB hardware design, embedded systems programming, and software application development. I specialize in full-stack electronics design for IoT systems, covering cloud integration, BLE, and RF wireless communication. My background includes digital signal processing (DSP), electromagnetic simulation, and machine learning for data classification, image recognition, and audio processing. I’ve also built strong skills in application development, database integration, and 3D modeling for enclosure design.
I founded Future Technologies Laboratory LLC in 2015 with the goal of providing complete electronics and software engineering solutions. Today, I lead a talented team of engineers to fulfill the requirements of complex projects and ensure they move efficiently from concept to production.

13 years of experience in all aspects of RF design and high-speed PCB development, including antennas, RF front-end circuits, RFID systems, BLE/Wi-Fi/LoRa products, RF components, impedance matching, filters, amplifiers, RF switches, baluns, and antenna tuning. Much of my work has involved RF PCB design, wireless product development, and high-speed digital hardware. This background also extends to RFID readers, transponder-based systems, and FPGA-related hardware projects.
I have strong experience in RF and antenna simulation using tools such as HFSS, CST Studio Suite, and Ansys tools for antenna design, RF matching, radiation pattern analysis, impedance optimization, RF front-end validation, and wireless performance improvement.
I have strong experience in high-speed PCB design, including multilayer board layout, controlled impedance routing, differential pairs, signal integrity, power integrity, EMI/ESD protection, RF grounding, shielding, and manufacturability. I have worked on FPGA-related projects involving Xilinx, Zynq, Artix-7 FPGA platforms, including data acquisition, signal processing, timing-sensitive interfaces, and high-speed digital board design.
My embedded hardware experience includes the setup, integration, and debugging of microcontrollers and embedded platforms such as STM32, ESP32, ESP32-S3, Nordic nRF52832/nRF52840, Raspberry Pi, Arduino, and embedded Linux-based systems.
I am familiar with RF and wireless ICs/modules including Semtech SX12 series LoRa devices, Nordic BLE chips, ESP32 wireless modules, Quectel LTE/GPS modules, u-blox GPS modules, RFID reader modules, RF filters, LNAs, PAs, RF switches, baluns, and matching networks.
For PCB design, I use Altium Designer, KiCad, EasyEDA, Eagle, and OrCAD
I also have experience with enclosure design for RF and embedded products, including plastic and metal enclosures, antenna placement, RF keepout areas, mechanical fit checks, connector positioning, thermal considerations, waterproofing concepts, mounting features, and PCB-to-enclosure integration. I understand that enclosure design can directly affect RF performance, antenna efficiency, heat dissipation, usability, and manufacturability, so I always consider the mechanical structure together with the electronics.
I have worked for years on IoT devices, wireless sensors, RFID products, antenna-integrated PCB designs, FPGA boards, digital electronics, embedded controllers, data acquisition systems, and prototype-to-production hardware. System engineering and integration have been important parts of many of my projects, especially where RF, firmware, FPGA, PCB design, and enclosure design must work together reliably.
My main strength is not only designing a schematic or PCB, but building complete hardware that works reliably in the real world. I always consider RF performance, signal integrity, grounding, shielding, power stability, EMI/ESD protection, enclosure integration, manufacturability, testing, and long-term reliability from the beginning of the design.
