Experience

Founder and CEO at Tzofan Cyber Ltd.                                                   July 2016 - Present

      With suite of innovative ciphers and algorithms - Tzofan brings new approach to                 protect wireless data communication within critical infrastructures and mission critical         devices where security can't tolerate any compromise.

      Implementing highest grade security on the most challenging IOT to GW comms with

      efficiency that compensates the limited computation constraints and limited battery           operated power resources.

 

Real time SW Eng. at Afimilk Ltd.                                                       2008 - 2016 (8 years)

      Developed from scratch (including CPU and radio selection) the firmware of wireless           network of battery operated tags that communicate the cow's profile of health, fertility       and eating/drinking habits, operating at extremely low power 5 years on a single 1000         mAmp button cell battery. I designed a proprietary sub-GHz communication protocol         with capability to concatenate lost packets to bridge up to 12 hours no-comms without       loss.

      Developed the firmware of the next generation milk-meter including pulsation control,       automatic removal, accurate milk yield and milk conductivity and temperature.                     Developed the firmware of accurate weight for cows during walking including the               mathematical model and algorithm

      Developed the POC and evaluation platform for sensors in the dairy farm including             MEMS accelerometers, proximity sensors, temperature, pressure, optical reflection             and absorption.

      Developed logger tag that writes to micro-SD card the records from various sensors           providing 3D accelerometer, battery level, and temperature at 50Hz sampling rate for         accurate lameness detection, ear tag and rumination monitoring algorithm                           development.

      Developed Bluetooth wearable sensor to log accurate (0.1 °C ) cows' temperature,             interacting via Android Smartphone application.

 

Embedded Software Engineer                                                          2004 - 2008 (4 years)

      Developed firmware for network of Fire detection sensors to the large industrial scale         (airports, campuses, hospitals). The network includes over 20 types of sensors with               multi-level clusters.

      Developed simulation module to test system load and alarm scenarios. Develop                 supervision modules, indicators and self diagnostics.

      Verified the system approval and compliance with the NZ and AUS fire detection and         alarm in buildings standard.

      Developed boot-loading capability and supervised firmware upgrade in modules                 across the network
