Experience

• Biosensor / EEG Hardware Engineer (PCB Design) Niura (Mindtune) · Full-time Mar 2025 – Aug 2026 1 yrs 5 mos Wah Cantt, Pakistan Owned EEG hardware and PCB design for next-generation wearable brain-sensing devices. Designed the EEG signal chain and bioelectrode interface around the TI ADS1299 8-channel analog front end, covering the electrode-to-ADC path, right-leg drive and CMRR optimisation for sub-microvolt scalp signals. Responsible for multi-layer PCB stack-up, partitioning and layout in a compact wearable form factor, including analog/digital isolation, low-noise power distribution, shielding and ground-plane strategy. Selected and characterised high-precision ADCs and supporting components for low-noise, low-power acquisition, validating performance with internal test signals and precision dividers instead of costly simulators. Led prototyping and design iterations against FDA-oriented design controls and documentation, and worked with firmware, software and product teams on end-to-end bring-up, SPI/DRDY timing and field debugging with logic analysers and JTAG.
• Technical Consultant - Hardware & PCB Design Zinovaa · Freelance May 2025 – May 2026 1 yrs Islamabad, Pakistan Remote hardware and firmware consultant to the engineering team. Reviewed schematics, PCB layouts and component selections before release to fabrication, and guided embedded system design and hardware architecture decisions. Advised on IoT, Bluetooth and microcontroller-based products built on ESP32 and STM32, supported firmware development, debugging and optimisation, and ran remote troubleshooting sessions on hardware-software integration issues. Contributed technical documentation and best-practice guidance so the team could ship repeatable, high-quality designs.
• Lead Embedded Hardware Engineer (PCB Team Lead) Revive Medical Technologies Inc. · Full-time Nov 2024 – Mar 2025 4 mos Rawalpindi, Pakistan Led the PCB and embedded hardware team at a medical device manufacturer, owning board design, fabrication, testing and implementation end to end. Managed BOM development and component sourcing, supervised in-house PCB printing and fabrication, and held the team to consistent quality and documentation standards. Delivered multi-layer, impedance-controlled designs with close attention to signal and power integrity, and coordinated with firmware, mechanical and production teams to hit project timelines. Also handled PLC programming and simulation on Siemens S7-300 and S7-1200 in TIA Portal, with Factory I/O simulations for industrial process control.
• Embedded Systems Engineer - PCB Design Revive Medical Technologies Inc. · Full-time Jun 2024 – Nov 2024 5 mos Rawalpindi, Pakistan Owned the PCB domain for medical device programmes: schematic design, multi-layer layout, component placement, fabrication, testing and implementation. Designed the DermScope REVIVE carrier PCB, a 4-layer impedance-controlled 90x62 mm ENIG board for a handheld dermatology imaging device, hosting an NXP i.MX6UL system-on-module with a MIPI CSI 4-lane camera interface, MIPI DSI 4-lane 2K touch display plus HDMI and LVDS outputs, GPIO-driven cross and linear polarisation optics, TP4056 Li-Ion charging with over- and reverse-voltage protection, SD card and 2 GB NAND storage, four USB 2.0 host ports with OTG and TTL debug, Wi-Fi, Bluetooth, 4G LTE NB-IoT and GPS, and an MCP3208 8-channel 12-bit SPI ADC. Also supervised in-house PCB printing and prototype builds.
• Trainee Embedded Engineer - PCB Design Revive Medical Technologies Inc. · Internship Feb 2024 – Jun 2024 4 mos Rawalpindi, Pakistan Joined as an embedded systems intern and moved into a trainee engineer role. Supported development and testing of embedded hardware and firmware, assisted on schematic capture and PCB layout in Altium Designer for STM32-based boards, worked on layout, signal and power integrity tasks alongside senior engineers, debugged hardware and firmware issues, and contributed to design documentation and process improvement.
