I'm a US-based RF design engineer with 17 years of experience delivering high-performance solutions in the aerospace/defense industry. I hold a PhD in Electrical Engineering and specialize in RF system design, PCB layout, antenna design, electromagnetic analysis, and rapid prototyping. Tools I work with include Keysight ADS (primary), KiCad (when preferred), MATLAB, and Python. I follow IPC standards for design/fab to ensure the quality of the end product. My work is ideal for companies looking to outsource complex RF, CAD, or electromagnetic challenges that require deep technical insight and a precision-driven process. I'm available full-time or part-time, can support any US time zone. Let’s talk if you need dependable, senior-level RF expertise without the overhead of full-time staffing.

I design medical-grade PCBs for EEG, biosensor and wearable devices - from blank schematic to a validated, manufacturable board. Most of my work sits where sub-microvolt analog meets high-speed digital. I have shipped 8-channel EEG acquisition hardware built around the TI ADS1299 (electrode front end, RLD/CMRR design, shielding and ground-plane strategy that protects a 1 uV signal), a next-generation health smartwatch (nRF5340, MAX86150 ECG/PPG/SpO2, BQ51003 wireless charging, ADP5360 PMIC), and a 4-layer impedance-controlled carrier board for a handheld dermatology imaging device (NXP i.MX6UL SoM, MIPI CSI/DSI, USB 2.0, LTE/Wi-Fi/GPS). What I do for clients: - Schematic capture and multi-layer PCB layout in Altium Designer and KiCad - Biosignal analog front ends: EEG, ECG, EMG, PPG, SpO2 (ADS1299, ADS1292, MAX86150, AD8232) - High-speed and mixed-signal layout: stack-up design, impedance control, signal and power integrity, EMI/EMC-aware routing - Wearable and battery-powered design: PMIC selection, fuel gauging (MAX17055), microamp sleep budgets, wireless charging - Design for manufacturing: BOM development, component sourcing, fabrication and assembly outputs, DFM review - Firmware bring-up and debug: STM32, nRF52/nRF5340, ESP32, bare-metal C/C++, SPI/I2C/BLE, JTAG and logic analyzer work Background: BS in Electrical Engineering from COMSATS University Islamabad, Altium-certified, and over two years leading PCB and embedded hardware teams at medical device companies, including design and documentation work aimed at FDA and regulatory compliance. I am comfortable owning a board end to end or dropping into an existing design for review, respins and debugging. Clear documentation, revision history and honest timelines come standard.
