I am a highly accomplished engineering professional with 10+ years of experience in PCB design, firmware development, and RF systems engineering.
I have a proven expertise in designing complex multi-layer boards, developing low-level firmware for microcontrollers and FPGAs, and creating RF circuits for wireless communication systems.
I am adept at the full product development lifecycle, from concept to production, with a strong focus on reliability, signal integrity, and regulatory compliance.
? PCB Design & Hardware Development:
? High-speed, multi-layer board design using Altium Designer, KiCad, and Cadence Allegro.
? EMI/EMC compliant layout, impedance matching, signal integrity.
? Power management, analog/digital mixed-signal design, thermal analysis.
? Experience with DDR, USB 3.0, PCIe, HDMI, Ethernet, and RF trace routing.
? Firmware Development:
? C/C++, Assembly for ARM Cortex-M, AVR, STM32, ESP32, and PIC.
? Bare-metal and RTOS (FreeRTOS, Zephyr) development.
? BSP, peripheral drivers (SPI, I2C, UART, ADC, PWM, CAN, USB).
? Bootloaders, OTA firmware update systems, low-power firmware optimization.
? Debugging with JTAG, SWD, Logic Analyzers, and oscilloscopes.
? RF Engineering:
? RF circuit design up to 6 GHz: antennas, matching networks, filters.
? Hands-on with Vector Network Analyzers (VNA), spectrum analyzers.
? Experience with ISM bands, LoRa, BLE, ZigBee, Wi-Fi, Sub-GHz radios (e.g., CC1101, SX127x).
? RF simulation using Keysight ADS, Ansys HFSS, CST Studio.
? Antenna tuning and testing in anechoic chambers.
? Tools & Technologies:
? Hardware: Oscilloscope, VNA, Spectrum Analyzer, Logic Analyzer.
? Software: Git, Jira, Python (for test automation), MATLAB.
? Compliance & Testing: CE, FCC, RoHS, UL testing, EMC/EMI analysis.
