Iran

- Responsible for delivering projects against agreed scope, budget, schedule, and customer expectations - Successfully managed six data acquisition and signal processing/monitoring projects worth up to $5M- Led and motivated a team of 10 engineers responsible for hardware design and implementation, firmware development, high-level software development, system debug, and project documentation- Delivered excellent customer service via overseeing risks, meeting customer needs, and keeping them up to date through regular customer interactions

Iran

- Digital protocol analyzer: Developed data link layer of Frame Relay network and MTP level of Signaling System No.7 (SS7) in a digital protocol analyzer. - Automation systems: Developed network applications for automation of different processes in office environments. The applications included socket programming and database acquiring.

Iran

- Portable medical monitoring system: Designed and developed a data acquisition system that captures several biosignals and displays them in a laptop. The system includes A/D & D/A chips, microcontrollers, DSPs, and CPLDs, and its interface to PC is USB 2.0.- Automatic vehicle location system: Employing MC9S12 microcontroller, GSM module, and GPS module, a device was designed to localize mobile objects. The system’s parameters can be set manually, using a keypad and LCD panel in a car, or programmed remotely from a base station.- Telephone voice ciphering device: Designed and developed a device which is placed between the line and the phone to provide a secured channel for communication in public networks, PSTN. Due to the redundancy imposed by the ciphering algorithms and to conserve the maximum baud rate allowed, a voice coder - MELP 2.4Kbps vocoder - was implemented on TMS320F2810.- PCM-11 multiplexer: Developed a control unit that handled the timing of multiplexing 11 telephone lines, using 68HC12 microcontroller.

Iran

- Conducted research on different methods of feature extracting from vocal signals to improve accuracy of a speech recognition system which is independent of speakers- Implemented a new method of feature extraction which improved the system accuracy by 5%
