Manager Hardware 01/2005 - 11/2010
Main Responsibilities:
Manage a team of engineers for project execution.
Interact with clients to understand their specifications and keep them updated on project status.
Prepare project feasibility reports and cost analysis of prototype and series production.
Manage design documentation and technical writing.
Carry out field testing and troubleshooting.
Propose circuit level design to engineers and guide them in design, simulation and implementation.

Main Achievements/Projects:
Successfully completed projects worth 220 million RS in my last 8 months at AKSA.
Designed a 280W Switching Mode Power Supply with 06 outputs. The design included the topology selection, transformer design & construction and feedback control. The power supply had to meet the EMC/EMI and other safety requirements. Forward Converter topology was employed with current mode control.
Designed a MIL-STD 810E compliant, 115VAC 400Hz, 8-output Switching Mode Power supply to be used in HUD (Head Up Display) system of F7P aircraft. This replaced the older linear power supply which was bulky and less efficient.
Re-engineered a highly complex Graphic Controller Card used in RoseI/II Mirage aircraft’s HUD system, originally manufactured by GEC Ferranti. The card was re-designed on an 8 Layer Hybrid PCB (Rogers4003+Fr4 Hi-Tg) over full Military temperature range of -55 C to +125 C and vibration/shock compliant o MIL-STD 810E.
Hardware Design Engineer 05/2002 to 12/2004
Main Responsibilities:
Design the key modules for the Error Correction Engine based on Reed Solomon CODEC and test using MATLAB .m file scripts. Prepare complete Simulation in MATLAB of the final Error Correction Engine.
Design Hardware units for the Implementation of the Error Correction Engine using Verilog HDL. Test the individual units in ModelSim. Tailor the Hardware for maximum efficiency.
Design the Hardware Board for the HDR including the Analog Front end and the High Speed Digital Interface based on Dallas 89C420 Microcontroller.
Main Achievements/Projects:
Implementation of interleaved shortened Reed Solomon Codec RS(255, 239) for use in the High Density Magnetic Card reader.
I was the key member of the team to design the complete Error Correction System to be used in our client’s High Density Card Reader Prototype (ISO-7811-7).
