Details Regarding Projects Execution and Responsibilities: Digital/ RF Electronics and Embedded systems Engineer Creative problem solver who has consistently completed projects on time and within budget. Technical proficiencies include Digital Signal Processing, Communication systems and extensive knowledge of Mixed Signal Board design. Finely-tuned analytical skills with a dedication to expanding subject knowledge and workplace competencies through continuing research and training; willingly assume extra responsibility to ensure optimal and timely project execution.

The above projects were completed using the following strategy by carefully achieving every objective based on projects timelines.

1) Finalization of User Specifications.

-Resource Required

-Operating frequency.

-Physical dimensions for the finished product.

-Application Information/ environment conditions

-Mechanical enclosure and Operating Temperature Range. 2) Simulation/development.

- The design phase start with free-form schematics simulations, using ADS for filters and VSWR calculations for Analog part of the hardware (IF any). Then based on the scale of the PCB and its components either Altium or ORCADE CIS is used for schematics. Pre- layout simulations are then executed using Hyperlynx. Afterwards Polar Instrument is used for stack-Up design and then finally layout and routing is initiated. Once the layout and routing is done. Post layout simulations are done that includes crosstalk and PDN verification using Hyperlynx BoardSim. 3) Integration and Testing

-After the Successful CAD design the necessary files for manufacturing i.e. Gerbers, NC drill etc. are sent to manufacturer and meanwhile the mechanical cavity/ assembly or enclosure is design using SolidWorks software. And the drawings are sent to machine shop after simulation of heat conduction is done using cadence Celsius. The connectors for best isolation and vibration compatibility are also decided while the mechanical design.

-Once the physical aspects of the hardware are met. The software or firmware part is initiated. Since the most of the PCBs I designed were based on Xilinx FPGA’s so I write the Firmware for testing in VHDL to verify the boards functionality, that includes all the interfaces e.g. ADC, DAC, DDS, UART, SPI, Ethernet, IO modules etc. 4) Qualification Tests

-Thermal qualification of the product from -40C to +85C.

-Vibration cycle of 6G's

-EMC/EMI testing

5) Field Testing

-The Field trials includes the testing and integration of boards with the rest of the system related to Communication and Radars in actual operational environment. The Firmware I write for the boards has API test module which shows the system health i.e. Temperature, Current, Voltage etc. 6) Quality and Configuration management Documentation

-During the whole process, worked in parallel with the Quality department and the CM department to ensure the quality of the final product.

Final Dissertation: RFID based Security System with Video Monitoring Developed a real time embedded system based on radio frequency identification and can be implemented in number of applications. But this project is dedicated for security reasons to allow specific vehicles or people to pass through the entrance without any physical contact with the gate also that place is monitored through an IR camera. System also generates a specific user ID and sends it to the computer which can be used to access and display the data of the person entering the Building, which is already stored in the computer.
