***** * Los Angeles Ave., Moorpark CA 93021

Embedded Software Engineer – Contractor through Aerotek

Enhancing Pentair’s Pool and Spa Automation System using QT Creator as the Interactive Development Environment, C++ with QT add-ons for WebSocket communication and QT Meta Language QML for the Touch Panel GUI, D-Bus for Inter-Process Communication (IPC), GIT for source code control and Red Mine for issue resolutions.

Designed, developed and completed the communication between the Control Panels running Real Time Linux on a TI ARM processor and the Web Server to update the Server with the Aquatic System Status such as Temperature, pH, Salinity, Pump and Filter and Water Purity and Chemical Levels.

Designed and developed the end of assembly line quality control verification procedures where devices such as valve actuators, temperature sensors are attached to the control board to verify the states of the devices by monitoring the devices heartbeat messages that also contain various device states. The same process will also be used by the support team to resolve customer’s issues that may arise in the field.

Facilitated wireless communications between control boards by selecting the optimum RF channel. The Received Signal Strength Indicator RSSI and Link Quality Indicator LQI from all the available channels are retrieved and analysed to determine the best channel to use.
