• Managed and led an international multi-disciplined teams to develop
applications to demonstrate the capabilities of the OCULI SPU
(Sensor & Processing Unit) a camera chip that reduces data redundancy
ensuring that only pertinent information is transmitted forfurtheranalysis.
• Delivered knowledge transferand training sessions.
• Replaced old obsolete FPGA development board Opal Kelly XEM6310
mounted on the SPU platform with another smaller Chinese one
featuring a Zynq FPGA, cutting the cost by 80%.
• Build a high speed interposer PCB that connects and voltage level shifts
bus to/from FPGA.
• Developed VHDL codes, and built Linux operating system for different
Zynq FPGAs on Xilinx software (vivado, vitis and petalinux).
• Developed people and face detection python applications.
• Handled technical communication with well-known companies, and
tested their advanced MCUs featuring AI engines with the SPU.

• Direct Involvement in Product Development: Actively participated in
the planning and execution of every feature and aspect of the
development process of Roadie an automatic, fast and accurate
standalone guitar tuner utilizing a vibration sensor (instead of a
microphone) for superior performance in noisy environments.
• Technical Leadership: Led a dedicated team in hardware and firmware
development, and implementation of Roadie 2, Roadie 3, Roadie Bass,
and Roadie Coach projects from the ground up.
• Hardware and Firmware Development for Roadie Series:
Spearheaded the development and implementation of the product
database on chip, screen graphics (OLED, TFT), Bluetooth Low Energy
(BLE), Over-The-Air (OTA) firmware updates, Wi-Fi, communication
protocols, real-time clock, motor control, GPIO expander, audio codec
chip, and charging circuit. Additionally, contributed to mechanical design
and PCB layout.

• Developed the SUBTEMP project for SUBWAY a Bluetooth Low
Energy smart contactless thermometer that measures food surface
temperature with an IR sensor and internal temperature using a
pluggable K-type thermocouple probe.
• Developed project circuit, firmware and mechanical design.
• Implemented a second-degree polynomial for error calibration.
• Documented the source code, created both technical and user manuals
and developed a wiki page for the device.
• Worked on Wi-Fi energy metering project utilizing ESP8266 device.
• Developed an internal Wi-Fi controlled switcher system to divert the
company intercom calls from all floors to the secretarys office.

• Worked on multiple customer projects and concepts to design and
develop new applications using Methode Sensor Technology.
• Engaged in cross-functional teamwork within sensors, HMI, and power
electronics groups.
• Implemented concepts, designed schematics and layouts and built user
friendly LabVIEW interfaces.
• Performed circuit, electromagnetic and thermal simulations.
• Researched various power electronics projects, including converters,
inverters, and power supply designs.
